“Tim was so helpful. He understood what I was trying to do with my dissertation research analysis and took the time to explain everything to me in a way I could easily follow. He helped me out of a real mess – and on a short deadline. He saved my doctoral program. I was about to give up! I highly recommend him.” – J. Gonzalez, doctoral candidate, Texas Tech University
“Tim is a wonderful statistics tutor. He explained concepts and SPSS to me in a way I could understand. Tim is skilled, smart and patient!” – Michelle
“Tim is an absolutely fantastic statistician and tutor! He worked with me one-on-one for several months, going through every statistical measurement & analysis method (using SPSS v.24) that was needed, explaining everything in a way that I could easily understand, & even helping me with the wording of the results. He was patient & kind, which really helped as I was under a lot of pressure at the time. I must give him a lot of credit for helping me obtain my PhD. I can’t say strongly enough what a positive experience it was! 😊” – Kathleen

“Statistics was a difficult course for me. I struggled the entire semester. I never missed a day of class, but I just couldn’t grasp the concepts. I did online tutoring with Tim a few days before my final exam. I received my progress report the day of my final exam, I had 67 points “D”. The final exam was worth 20 points, I passed the class with “B”! Thanks a million Tim!!! I couldn’t have done it without you!!!” – Keela
“I cannot express how wonderful and appreciative i am with the tutoring that i received from Tim. I had the pleasure of having him as my professor and as my dissertation reader.

You will not be disappointed! :)” – Raquel

“I would like to give an outstanding review of Tim’s ability to assist with statistics. I have a PhD in psychology and decent stats training, but needed Tim to assist me with some more complicated questions regarding a few papers I am working on. In this capacity, Tim was extremely helpful, and his extensive knowledge about different types of statistical models (both in terms of research design, and interpreting SPSS output) was quite evident. I have worked with Tim now on numerous projects, and he has been very helpful each time we work together. I would highly recommend him to undergraduate or graduate students needing help with their research, or more senior investigators needing a statistical consultant. Thanks Tim!” – Brandon
“Tim is everything you could ask for in a tutor. Very knowledgable, supportive and easy to work with. I highly recommend him!!” – Holly
