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.

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.

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!

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.

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!

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!

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.

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!

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!

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!

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.

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!

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!

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!

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.

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.

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.

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.

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.
