Tutoring in SPSS, Modeler, data mining, & stat. analysis/modeling

I am currently an educational/statistical consultant for SPSS, an IBM Co. I am an IBM Certified trainer in SPSS and Modeler and teach SPSS and Modeler classes part-time for IBM. I retired from IRS in Dec. 2007, after 32 years with the U.S. Federal Government.

Donald was attentive, patient, and thorough with his explanations. He came very well prepared and even sent me some helpful information following the session. Highly recommended!


Jeffrey D. from Atlanta, GA

Donald was an awesome tutor. He helped me with completing my statistical analysis, as well as the write up of results and conclusions for my dissertation. I highly recommend him!


Anthony A. from Peachtree City, GA

Donald's profile was very attractive to me when looking for a tutor so I selected him to help me with understanding SPSS. Donald was on time, patient, very respectful and at the end of the lesson I felt I had achieved a lot of knowledge that would certainly help me along the way in my doctorate program. I highly recommend him and thank him immensely for sacrificing his time to help people like myself even though he is retired.


Laurette V. from Suwanee, GA

Don was instrumental in helping me take the SPSS modeler text analysis output to the next level of finding deeper insights. I was only familiar with these options in the old text program, but he brought them to light in the latest modeler version. On our next session, we'll go one step further by using the actual modeler nodes to see if we can model any of the text output categories to other dependent variables in the full dataset. Thank You Don!


Dana W. from Snellville, GA

Donald was not only extremely knowledgeable in helping me with my Ph.D. level statistics research practicum, but also down to earth. He was extremely timely in returning correspondence. He was easy to talk to and I felt comfortable asking him any questions I had. He found a way to make things easier to understand because he meets you at the level you are. I would definitely recommend him and plan to utilize his services if I need any assistance with my dissertation research design!
