Kristan H. from Grove City, OH Jonathan has been a bigger help than I had originally imagined. My grade has steadily stayed at or near the "A" mark, and without him I would have definitely received a "C". I really appreciate that Jonathan is on-time and frequently early. He immediately is prepared for my questions and is able to provide me with the proper steps to obtain the solution quickly and with no hesitation. I am taking Technical Mathematics, and Jonathan has no problems guiding me through the difficult problems. I am truly grateful I have Jonathan as a tutor and I look forward to having him assist me with other difficult classes I may need help with. Jonathan will always be the tutor I refer to others in need.

Karen C. from Dublin, OH I can't say enough positive things about Jonathan. He is a great tutor/teacher. He has been tutoring my daughter in Algebra 2 and also Chemistry. She has really thrived under his guidance. He has great patience and put her at ease immediately. Her grades have improved but also importantly, she is understanding the concepts because of his kind and gentle teaching method. Jonathan is always prompt and makes it a point to communicate with us about her progress. He has been most honest and straightforward and we quickly came to trust him and his impressions of our daughter's strengths, as well as weaknesses. I absolutely recommend Jonathan to anyone who is considering a tutor. His teaching style is unsurpassed!

Wendy B. from Dublin, OH Jonathan is an excellent tutor. My son is very comfortable with him. Jonathan adapts his teaching style to fit my son's learning style. Jonathan always arrives on time, he is willing to take a few minutes at the end of the lesson to talk to me about the progress they are making. Jonathan has been very willing to work my son into his schedule for extra sessions as needed.

Gail D. from Galloway, OH We have been very pleased with the tutoring services provided by Jonathan and highly recommend him. Our son had fallen behind in Geometry and, almost immediately, Jonathan was able to help our son get his feet back underneath him in this challenging subject. Not only does Jonathan explain the concepts, but he reinforces the thinking skills and processes that allow our son to successfully apply those concepts later when he is at school or working on his homework. Jonathan is professional, punctual, and very good at what he does. We would highly recommend him to anyone needing an effective tutor who can start making a difference from day one.

Shelley B. from Dublin, OH Mr. D. is a thoughtful, patient and reliable tutor. He adapts so the student receives the specific support needed and can flex between subjects as well. And he has always been easy to reach and responsive when scheduled sessions had to be adjusted. Very much appreciated for busy students and parents.

Sarah B. from Columbus, OH Thank you Jonathan for an excellent tutoring session. Jonathan is super knowledgeable, helpful, and kind. I would recommend him to anyone for all their tutoring needs!!!

Tammy H. from Columbus, OH Thanks to Mr. D, I was able to not only pass my Labor Economics course but gain a better understanding of the concepts and theories behind Labor Economics. Mr. D is very professional, and very knowledgeable of the principles and explained them using examples that made sense and helped tremendously in making it all come together. I highly recommend Mr. D for tutoring and without his assistance I know I would not have made it through the semester.

Samer C. from Columbus, OH I've had a wonderful experience with Jonathan. I'm a construction management major and he has helped me through several classes. Jonathan has a very good understanding about science math and the construction industry. He's always ready to help you out and better make you understand the material so that you can succeed in whatever classes or degree you are pursuing. I thoroughly recommend Jonathan to anyone going into sciences and math of some sort. I'm sure you will have a pleasant experience just like I have had.

Marietta K. from Columbus, OH My daughter is a sophomore in college, and she was having a challenging time in Chemistry. We contacted Jonathan, and he began helping. He was very flexible with scheduling sessions for tutoring. He helped her work through her confusion on the subject, and he restored her confidence in herself on the subject matter. My daughter's final grade was an A in her chemistry class. I give Jonathan the highest praise for a job well done, and I would highly recommend him to anyone seeking his tutoring expertise.

Duru E. from Columbus, OH Great tutor! It was very easy to set the sessions. After each session, the tutor has always provided information on the materials covered during that session. My daughter's grades have significantly improved since she started to study with Jonathan.

Rick S. from Columbus, OH I took the micro-econonics course for Buisness majors at Ohio State. Before working with Jonathan I did not understand what was going on in the course. My teacher did not provide any notes, practice problems or examples. I received a 68 on my first midterm. After that I sought out help and found Jonathan on this site. My understanding for the subject improved drastically after working with him. He provided clear explanations and examples for each of the topics covered. Before I had tried to memorize all of the equations and vocab words, after Jonathan's help there was no need to memorize anything because I actually understood the rationale behind each topic. The following midterm I received a 96. With his help I was able to work my final grade up to a B+. I would highly recommend him. He was able to instantly transform my thinking and save my grade.

Kathleen B. from Dublin, OH Jonathan is a very good tutor. He works WITH our son on the things he needs help on, rather than just talking at him. The other night, our son said, "Wow, I was totally lost in Chemistry and [after my session with Jonathan] I really understand it now!" I thought that was the best endorsement. Jonathan's manner is very kind, professional, and patient. He also really knows Chemistry. He is punctual and trustworthy. I would highly recommend his services!

Shelley W. from Columbus, OH My son had four tutoring session with Jonathan for ACT Math. Those four sessions (and work at home studying what he learned) helped raise my son's ACT math score by 4 points!! Jonathan is very patient. He has an ACT Math book that he teaches from and continues to work with my son until he understands each concept. He also shows him different approaches and logic to solve certain problems. He gave him tips for taking the test as well. He is very prompt at responding to e-mails and is easy to schedule sessions with. He is a great guy that my son enjoys working with and we are thrilled with the results!

Tracy M. from Hilliard, OH My daughter has always struggled with math. However, with Jonathan's tutoring, she has raised her math grade by a full letter. Jonathan has explained Algebra 2 in a way that she can comprehend. He is very knowledgeable and quite capable of explaining complex algebraic concepts in understandable terms. I would highly recommend Jonathan to anyone needing an Algebra 2 tutor.

Bruce B. from Columbus, OH My expertise with Microsoft Excel is very basic. Jonathan was very professional, knowledgeable. He briefly studied my spreadsheet to see where the problems were and then included me in correcting the problems. After Jonathan made a few corrections and presented better options as I observed. We both proceeded to make all corrections and dress up the spreadsheet. He made sure I was able to do the corrections by myself with him observing. The many shortcuts were most helpful. I now have my accounts in a very nice visual and printable spreadsheet. I will not hesitate to call on Jonathan and WyzAnt should I need further help.

Michelles S. from Lancaster, OH Jonathan seems to have a deep understanding about all things chemistry. He is very patient and is able to relate the material on several levels so you can gain an understanding of the concepts. I have no complaints.

Julie C. from Westerville, OH Jonathan is prompt and gets right to work. My son wants to be prepared and Jonathan works well with him. I think an engineering background is very useful since it takes allows my son to see the practical applications of what he is learning. I pay attention to most of the lessons and am impressed that Jonathan will allow my son to approach a problem his way and only correct him if needed. My son now knows that there is usually more than one way to set up a problem.

Lisa K. from Columbus, OH Jonathan is an extremely bright and knowledgeable individual. My son had been struggling in an upper-level college Economics class. Jonathan agreed to work with him, and not only helped him improve, but really to exceed in the class. Jonathan is very responsive and flexible in scheduling. He truly seems to care about helping students succeed. I was not sure, at first, whether Jonathan would be a good match for Economics given his Engineering degree and background. But he not only understood the material, but has a talent for explaining the material in a clear and concise manner. I would highly recommend Jonathan to anyone looking for tutor in any subject matter.

Patti R. from Columbus, OH Jonathan was tutoring our son to take his ASVAB test. He was able to help improve the score by 17 points! Patient and thorough.

Darlene H. from Springfield, OH Jonathan has honestly amazed me with how efficient/proficient he is with regards to teaching. My daughter excels in language arts and the like, but math and science have always been an uphill battle for her. Jonathan has a very soft-spoken, yet authoritative presence about him which made my daughter immediately feel at ease with him. And due to his approachable nature, she felt comfortable admitting when something he said did not "click" with her, until I finally began hearing the sounds coming from the next room that's simply music to any parent's ears whose child is struggling with something: "OH, OK! Now I get it!" I would recommend Jonathan to anybody who needs assistance with ANY of the subjects in which he specializes, because he is not only knowledgeable beyond belief, but is equally likeable and approachable.

Gabe T. from Reynoldsburg, OH I'm currently using Jonathan to help me study towards my master and I can't tell you how lucky I am to have found him. Jonathan is a great teacher and is worth every penny.
