Alexis

Richard T. from Herndon, VA

Alexis has been a gift to our son's mathematical education, and has reignited his love of math. Alexis enthusiastically provides in-depth instruction, chooses appropriate lessons on his own, and goes above the call of duty. Alexis is a treasure and a true find for our family.

Maryellen L. from Wethersfield, CT

Alexis is an excellent teacher. I was lucky to find him. He's patient, knowledgeable and understanding. He responds promptly to emails and makes an effort to work around your schedule as best as possible.

Wamiq H. from Ashburn, VA

My son is getting 10th grade Math (hon) tuition from Alexis and it has really been very helpful. Alexis knows his subject very well and teaches it in a very friendly manner. My son has increased his grades in Math after he started tutoring with Alexis. I would highly recommend him for Math tutoring.

Kimberly M. from Germantown, MD

Alexis has provided me with the necessary background knowledge that is needed to pass the Praxis 2 mathematical content exam. He is truly knowledgeable, patient, and easy to work with.

Chun C. from Chantilly, VA

We are glad to find Alexis as my son's tutor for C++ programming. Alexis is intelligent and well informed. The online lessons have turned out very well over Skype.

Kathy Z. from Sterling, VA

Alexis has been tutoring my daughter for more than two years in subjects ranging from Algebra, AMC 10, 12, AP Calculus AB, and now to AP Calculus BC whenever she has problems. He is very talented, has deep knowledge in all areas of math, and all the lessons with Alexis were very productive. My daughter has been in a magnet program since high school, so all her math assignments were extremely challenging. Alexis has been the only one who can answer and explain all her questions clearly and proficiently. Alexis is always punctual, patient, responsible, and has a very friendly personality. We are so lucky to find him.

Harry E. from Bethesda, MD

Alexis' tutoring of one of my boys on advanced subjects such as Logic and Advanced Calculus has been so helpful that I have asked him to help my youngest son in first year calculus!

Anna H. from Annandale, VA

Mr. H is a phenomenal tutor. He is very reliable and very responsive, and I'm so happy we found him to be my son's AP CS tutor. My son was really struggling with his JAVA labs in AP Computer Science in the beginning of the school year when I reached out to Mr. H. Mr. H understands his school's curriculum very well. He always spends time understanding my son's labs and gets well prepared before each lesson. He takes his time to guide my son through the labs and help him understand the content thoroughly. My son really enjoys taking lesson from Mr. H and now he is much more confident with his AP CS after two months working with Mr. H. Mr. H is very caring and responsible. He often extends the lesson without charging extra cost. He is also very flexible with the lesson schedule. As a parent, I can totally trust him and rely on him because I know he is a very reasonable and reliable tutor. I'm extremely pleased to have him as my son's tutor. I would highly recommend Mr. H to anyone who needs help in computer science.

Hardik P. from Ashburn, VA

Alexis is a great tutor and extremely easy to work with. He understands the subject thoroughly and explains in easy to understand manner. I have taken multiple lessons from him for differential equations, poisson solvers and other very difficult problems which he walked me through successfully.

Anju W. from Ashburn, VA

Mr. Alexis is a great tutor. At the end of last year, he not only helped me understand the Foundations of Computer Science material, but also taught me new concepts and techniques to keep me ahead. He is also very easy to contact and is very flexible with times, which helps out a lot. I would definitely recommend him to other students.

Latha S. from Herndon, VA

My son has had four tutoring lessons with Alexis via Skype. Alexis has been an excellent tutor for my son in Precalculus. He has a wonderful way of explaining the material. He has gone above and beyond to work with my son's schedule to help him prepare for the Precalculus test. I would highly recommend Alexis as a Math tutor and would not hesitate to use his services again.

Lopa P. from Ashburn, VA

Alexis had been extremely valuable to my daughter by helping her out with Foundations of Computer Science, as well as Algebra with Trig. Comp sci was a challenge and Alexis not only helped in turning her grades significantly, his passion, knowledge and patience also helped my daughter to develop passion for a subject she was uncomfortable with. An invaluable tutor for computer science as well as math.

Aaron P. from Elon, NC

This man is a genius! He understood everything and was patient enough to explain it all to me until I understood. Never going back to my old tutor, Alexis was extremely helpful!

Christina G. from Dekalb, IL

I hired Alexis to help with my Java class. I've learned a lot from every session, and Alexis has been able to answer all my questions quickly and thoroughly. He is also very quick to respond to e-mails and requests for additional tutoring sessions. Because I live in a different state than Alexis, we have had all sessions over Skype. Before my first session I was a bit concerned that having tutoring lessons over Skype rather than in person might be difficult, but this has not been a problem at all. In fact, tutoring over Skype is great because I can share my screen with Alexis and we can talk through topics while looking at the same code. I'm very happy I've found Alexis and I would recommend him to anyone needing help with Java.

Allison B. from Great Falls, VA

Alexis has knowledge beyond the curriculum, which he uses to make things more understandable. He is very thorough and teaches math in a step-like procedure, emphasizing the importance of knowing each step before proceeding to the next. He is patient and easy to work with. My son truly enjoys working with him!

Yvette G. from Reston, VA

There isn't a question he can't help with, and this is such high level math! His lesson time flexibility is also deeply appreciated!

David G. from Sterling, VA

I am in Algebra 2, and after just two lessons with him, my grade began to increase. He is very easy to talk to, and will answer questions that you may have without hesitation. He is knowledgeable in every area of Algebra 2, and he really helped me improve. He is also very flexible and has stayed longer than we planned more than once, free of charge. Thanks Alexis!

Michael K. from Joppa, MD

Awesome tutor. Will definitely be using again! Very patient took his time with. Was able to meet online and worked very well. Thanks Again!

Jorge L. from Chantilly, VA

Alexis knows what he is doing. He teaches and corrects as you go. I recommend him for any programming subjects.

Sheryl C. from Great Falls, VA

One Friday night last summer my son expressed interest in a tutor for his college JAVA class. That night I looked on Wyzant, and Alexis responded to my inquiry within minutes. At our request, he was at our front door on Saturday morning -- how fortunate for us. Alexis is an outstanding tutor, supporting my son with understandable, practical explanations and the tools necessary to do well in class. His passion and enthusiasm for what he does is infectious, and our son is so excited to start working in the computer world upon graduation. I am a Ph.D. in engineering, and I can fully say that Alexis does a terrific job. My son is now away at college and continues to have regular sessions with Alexis via SKYPE. It is an integral part of my son's success in his programming classes, even going beyond what is being taught in the classroom to expand his knowledge and prepare him for the workplace. Alexis also does calculus tutoring and my son will be using Alexis for those classes as well. Alexis does math, algebra, calculus and computer tutoring for high school students, and I highly recommend him.

Xander H. from Clifton, VA

Alexis has been a brilliant addition to our homeschooling. My child loves the challenges that he brings. Alexis has a genuine passion for math and computer programming, and will be a great benefit to anyone needing help or even looking for that extra challenge. He is also very knowledgeable and full of ideas on ensuring that you understand the material. He is very prompt and fantastically and wonderfully quick to respond to any questions that you may have concerning math and the material that you are covering. You can tell that he genuinely wants you to succeed and will do his best to help you. He's also really nice. It would be hard to imagine a better tutor!

Susan D. from Gainesville, VA

Alexis is an awesome tutor! He is patient and makes even the most complex topics easy to understand. He is very flexible with his hours and is available on Skype which is a huge plus. It is very hard to find tutors who understand advanced math, so having access to Alexis has been a God-send!

Renee D. from Sterling, VA

We are very impressed by Alexis. He works full time and tutors a lot of people yet, you would never know it by his energy level. He really knows his materials.

Karen E. from Vienna, VA

Alexis is an excellent math tutor with an outstanding ability to explain concepts in clear language. My child was struggling in AP Calculus in the first semester but with Alexis' help, earned an A- in the next academic quarter. I would recommend Alexis very highly!

Sharon C. from Great Falls, VA

My daughter has been taking lessons with Alexis for three times. Her grade has already jumped to a high A-. That is how excellent this teacher is. Thank you, Alexis!

JR V. from Herndon, VA

Alexis has been tutoring our son since late Fall 2012 and his grade in AP Calculus has gone up two letter grades. Alexis always provides a great tutoring lesson in AP Calculus - very patient and knowledgeable, and he is always on time and prepared to teach. I wish we would have contacted him earlier; I would highly recommend him as a math tutor.

Matt K. from Great Falls, VA

Alexis has been helping our student with Algebra II. In addition to covering all the standard curriculum very well, he often goes the extra mile by going over advanced problems (i.e. 'AMC'/'AMEE' questions) to help him prepare for toughed test problems. Our student and we are very pleased. Thanks Alexis!

James F. from Newark, DE

Alexis is great at providing additional insight to further your understanding. Reading the text is great and working real examples produces better results. Alexis distills this information into understandable and bite size chunks to better consume and grasp. He does a great job!

Scott P. from Sterling, VA

Our experience with Alexis was absolutely outstanding. My son was struggling with a higher-end math course in college, necessary for his curriculum, and laboring with a less-than-ideal professor. My son began sessions a few weeks into the semester, and they prevented what would otherwise have been a disaster. Alexis is a truly gifted individual, with an uncanny natural mathematical ability combined with the rare talent of being able to convey complex ideas in a manner that makes them accessible and understandable by the student. Additionally, Alexis is personable, punctual, meticulous in responding to contacts, and very easy to talk to. Should my son encounter difficulties in future courses, I know where we will turn. I would heartily recommend him as a Class-A, top-of-the-line tutor.

Sharyl A. from Leesburg, VA

It's HARD to find a knowledgeable calculus tutor. After failing to find help through the school's county list, I was desperate and googled online. Alexis is not only knowledgeable-- but when we explained we were in an emergency situation with material due the next day that nobody had been able to help with, he came to our house late at night and got the job done cheerfully. My high school senior daughter thoroughly enjoyed the session and understood his explanations. And instead of acting tired late at night, Alexis said he was "energized" by doing the math. You won't be disappointed with Alexis! Thank you thank you!

Michael B. from Herndon, VA

My son really enjoyed his first tutoring session with Alexis H! He cleared up the things he was confused about. He is now convinced he can succeed in this AP Calculus AB class. Thank you for sending such a passionate tutor! He made learning fun for my son. Thank you, grateful mom.

Sylvie T. from Leesburg, VA

Alex was fabulous. After completing my MBA 15 years ago, I decided to pursue a PhD in Business Management. I needed to rewrite the GMAT (17 years since I last wrote it!). I had forgotten far more than I remembered. After a couple of frustrating months of trying to teach myself, I started working with Alex. He was so much help. I wrote the GMAT and got a GREAT score! Thank you Alex.

Sandy M. from Sterling, VA

Alexis responded quickly to my emails. He was prompt and likeable. He provided good explanations and made my son feel comfortable with the tutoring session.

Jyothi R. from Mc Lean, VA

Could not have asked for a better instructor. He has patiently worked with my daughter focusing on ensuring that she understood the content and never looked at the watch. Very happy to recommend to my friends and family!

Ryan R. from Fairfax, VA

Alexis helped me with learning about constructors, initializer lists, and scope resoluters when dealing with vectors and functions dealing them as well as using "this" and left side of member functions.

Tim B. from Arlington, VA

Got through a large amount of material in a short amount of time. He was very helpful and friendly, easy to ask questions and get them answered.

Katharine H. from Lisle, IL

He is very patient, he worked with me until we were able to solve a problem I was having with my program. I would highly recommend Alexis as a tutor!

Angelina Y. from Bolton Landing, NY

Alexis is very responsive and accommodating. When we contacted Alexis on a Thursday to set up emergency tutoring sessions for our son in C programming language on Friday, Saturday, and Sunday to prepare for an online course final exam on Monday, Alexis replied right away and was able to accommodate our son on very short notice. Our son thinks Alexis "radiates intelligence", possesses a thorough understanding of C programming language, and is skilled at presenting the material. Our son was really struggling with various sections of the course material, and he was losing confidence in his ability to learn the material. After the first session with Alexis, our son was already feeling better, and by the end of the third session, our son was smiling again, his confidence restored. Our son is looking forward to continuing working with Alexis as he deepens his knowledge of C and learns new programming languages.

Patrick B. from Ashburn, VA

I have been working with Alexis since last school year when I took BC Calculus. Alexis is one of the smartest tutors I know. He is not only able to solve problems you are having trouble with, but is able to fully explain how to get the step-by-step answer in a way that is always crystal clear. I'm pretty sure he is advertised as a BC Calculus teacher, but he is so knowledgeable that he offered to also tutor me in multi-variable calculus. Definitely knows his stuff and without a doubt is the best source of help you can get in calculus-based math.

Andrew W. from Durham, NC

Alexis modified his schedule to work with me at the last minute. We completed an assignment that I had been struggling with, and I learned more while completing it under his guidance than I did in a week of class.

Jingyu H. from San Francisco, CA

Literally, tutoring with Alexis is as efficient as 5 times in classroom. He not only teaches tricks but most importantly teaches you the industry standard on doing the CS projects, which is very useful, the benefit may not be very obvious right now, but it will give us greater good in the future.

Jane S. from Harrisonburg, VA

Alexis is a patient, dependable and very knowledgeable college level math tutor. He has tutored my son through calculus III and now linear algebra. He is a true gem. Thanks Alexis.

Tarek K. from Mc Lean, VA

I have been working with Alexis mostly on computer programming. Although he is not proficient in the computer language we were doing (gfortran), he easily picked it up and was able to teach it to me as well as help me solve many of the problems. I never did tutoring sessions over Skype, however it went very smoothly and saved me a lot of time and money. I highly recommend Alexis to anyone inquiring his help in the subjects he offers!

Muhammad A. from Montgomry Village, MD

I am absolutely horrible at java, in an hour and a half I learned more about code than I have the entire semester. I plan to use him in the future

Amit S. from Ashburn, VA

He tought my son some concepts in integration so he can stay ahead in class. My son found him easy to understand and is looking forward to getting additional lessons from him.

Maggie N. from Atlanta, GA

He really helped me clarify some concepts that I had been struggling with and complete my assignment in a timely manner!

Jesse K. from Fargo, ND

Alexis knows when to speed up in areas where you are already well versed, and slow down and explain trickier subjects. He held back enough to make me think while he helped me, but stepped in to help me when I needed it. Great tutor in java.

Phil M. from Ashburn, VA

Alexis, is very knowledgeable in the area of C and Java. He took his time and showed me all aspect of the project and different ways in which to look at the code as well. I would recommend Alexis for any project in dealing with programming and software development. 5 stars

Sunitha V. from Ashburn, VA

We got referred to Alexis by one of our family friends last year and are very grateful that they referred him . He helped my son with Precalc last year and this tremendously helped him improve his grade and regain in confidence and when ever my son needs help in math we know whom to reach he is back with him for AB Calculus and I know hez in right guidance .

Mohammad A. from Westport, NY

Mr. Alexis was kind and patient with me. He is very knowledgeable. I had difficulties with understanding and answering discrete math problems, but he explained them in a very simple way. I would definitely contact him if I have any other problems.

Kshitij A. from Chantilly, VA

He did a great job helping me out regardless what I asked him. At the moment, he was unable to answer one of my questions, however he did continue to look for answers after our section and give them to me as he found it. He goes into as much detail as you need and makes sure that you understand all the material.

Nishanth A. from Herndon, VA

I was having trouble with vectors, and Alexis' class was very helpful! He answered my questions patiently and explained the material very thoroughly. I will definitely go back to Alexis if I am ever having trouble with math again!

Tenisha W. from Gainesville, VA

Java was an extremely hard class for me. Thanks to Alexis I will not be repeating the course. He gave me the confidence I needed to succeed. He is very patient and knowledgeable. You can not go wrong with choosing Alexis.

Justine H. from Washington, DC

But Alexis was patient and hung in there. He was very thorough and his pacing helped me grasp.the concept and not just do the actions required to my goal

Otis H. from Tyler, TX

Alex was very knowledgeable about the subject that I consulted him about. I highly recommend him. He is patient and a very good with explanation.

Nawaf A. from Fairfax, VA

Alexis helped in my stat class. He is very clear in explaining the answers. Very helpful tutor, I encourage you to work with the gentleman.

Kurt D. from Chagrin Falls, OH

Alexis has helped me a couple of times with MIPS assembly language assignments (using MARS IDE). Not only did he help me complete the assignments, but he helped me understand the material and was able to answer any question I threw at him. Great tutor if you need help with some of the tougher aspects pertaining to computer science field.
