"Professor! I just wanted to let you know that I got accepted into some amazing programs for grad school! Particularly Georgetown's school of foreign service, which is among the top schools in the world for that area of study. I just wanted to say thank you and that you really are amazing!"

"Hiring Dr. Donnelly was the best decision I had made. I hired him for GRE prep when I was living in NYC. I had been out of college for 10 years and was going back. The field I was going into was very very competitive so a good score on the GRE was very important. I took the GRE after several sessions with Dr. Donnelly and received a great score and was accepted into the graduate program I had applied to. Without his help I would not have done as well as I did and more than likely would not have been accepted into the grad program. He is very patient and explains things in a manner that make sense and is very knowledgeable in this arena. I highly recommend him!"

"My son benefited tremendously from his tutorial sessions with Dr. Donnelly. Not only did he grow in confidence, but he was given the tools to expertly tackle his high school entrance exams. Dr. Donnelly is patient, consistent and totally committed to the welfare of his students and as a result of his thorough and knowledgeable sessions my son was accepted to all of the schools to which he applied. We are enormously grateful and cannot recommend Dr. Donnelly enough!"

"My daughter has worked with Dr Donnelly for the last three months and it has been wonderful. Dr. Donnelly has been able to focus on her weaknesses and provide enormous insight. In addition, his advice with regards to strategy for the test has been invaluable. He is able to engage students and provide support well beyond other tutoring services. He is sincerely committed to student success and offers a personalized service with sound methodology. Within 3 months her scores improved significantly. In addition to all his talents ... he is just one of those really smart people that can teach."

"Dr. Donnelly is a wonderful teacher. He is quick to pinpoint weaknesses and, in many cases, turn them into strengths. He always has a structured lesson plan and pertinent homework assignments and puts aside time in the lesson to go over "trouble problems" from the previous lesson. I highly recommend taking a prep course with him. His patience, humor, and kindheartedness makes an otherwise uncomfortable standardized test almost enjoyable."

"Dr. Donnelly is patient and supportive and is clear when explaining questions that were challenging to me. He also urged me to work out questions on my own, which was extremely helpful. He created an atmosphere in which I looked forward to the challenge of each section on the practice tests, and I definitely felt more confident taking the test. If I need to prepare for another standardized test, I will definitely contact Dr. Donnelly."

"The fundamentals I learned from Dr. Donnelly were very helpful. I received the one-on-one attention that I did not receive in the Kaplan prep test. I did not feel embarrassed to ask basic questions. Dr. Donnelly was very patient with explaining concepts in detail until I understood. Additionally, he was always available via email or phone."
