"Excellent tutoring skills and quick to follow-up"
- Emily, Minneapolis, MN on 10/23/13
David was very helpful and personable. I needed some help using SPSS to analyze the data collected for my dissertation. He contacted me almost immediately after I requested his help, and was able to set up a study session either that day or the next. He arrived promptly, and was extremely fair in his pricing and the amount of time it might take to accomplish my goal. David explained things patiently, was an excellent listener, and made an obvious effort to use examples that related to my experience. I would definitely recommend his services.
"Excellent Statistics Tutor for Any Educational Level"
- Sue, Cheswick, PA on 12/21/14
David started tutoring me in statistics as I began the data analysis stage for my doctoral dissertation and he continued working with me through my dissertation defense. He was very knowledgeable and upbeat throughout all of my sessions with him. I asked a whole lot of questions about what I was needing to do, and I appreciated that he explained the statistics to me very clearly and patiently. I wish I had known about him while I was actually taking the statistics classes during my doctoral coursework.
I defended my dissertation a week ago. Before my defense, David coached me on what to expect. He went through my PowerPoint presentation with me slide by slide and made concrete suggestions for changes in some of my slides. He also made sure I understood the data analysis thoroughly, so I could answer any questions about it that might come my way during the actual defense. I was well-prepared, and my dissertation defense was successful. By the way, I couldn't find a tutor in my local area who had the expertise to tutor me, so I invested in joinme.com and David taught me from three states away. Even from that distance, he was able to convey to me what I needed to understand to succeed in what I was doing. I would highly recommend him for anyone who is struggling with statistics at any educational level.

David is a very good tutor for quantitative subjects. Very intelligent and able to communicate concepts well. He helped me study for the quant section of the GMAT. He helped me understand the underlying concepts tested and then helped me build upon those concepts as our lessons progressed. Would definitely recommend.
"Really really smart!"
- Laura, Evanston, IL on 5/8/13
Great tutor. Explains and asks the student to explain. You hear things like, "what is the next step" and "when in doubt, go for the quadratic equation." After about 2 sessions, they really started to click and they are making great progress.
Seeing incredible progress! After a few weeks, the kid got his first A on a unit test of the year!!
**updated 5/8/2013** -- My kid came out of the tutoring session talking to me about practical ways of using statistics and probabilistic reasoning. David is AMAZING!

David assisted me with the Illinois state Test of Academy Proficiency. It is a basic test that covers basic math, reading and writing skills. I have always struggled with math, and thought I was doomed after I failed the TAP exam a second time, with minimal improvement. I hired David because of his strong mathematical background, and it turned out to be a fine investment. David helped me improve my test score by over 30 points. David is an excellent teacher. He is very patient and communicates very well when providing instruction. Overall, if you're looking for an excellent tutor, who will provide results, hire David.
- Ardak, Chicago, IL on 1/17/13
David is one of the best teachers I've ever had. The results speak for themselves. My initial GMAT score was 610. After studying with David I scored 50 points higher. Then I took two more lessons, and improved my score by another 30 points! He is Math genius! His knowledge in Math is so profound, that he can explain any math problem from various perspectives. He is also an incredibly nice person, who always gives more than is expected. Thanks to David I really improved my score.

"Gave confidence in confidence intervals"
- Stephani, Chicago, IL on 9/15/12
David went over all the questions I had selected to review for my up coming test. He was patient with me and made me understand concepts I thought I knew but was a little off on. I would recommend him to any student needing help with statistics.
- Ester, Chicago, IL on 4/26/12
I had the opportunity to work with David regarding decision making under uncertainty that looked at expected profits and the variance in the profits. This tutorial session was excellent. Not only was David punctual for our meeting time he was patient and explained each step thoroughly. I am a person who values my time and David exemplifies a person who applies quality to his tutorial services. I would definitely recommend him for future tutorial services.

"Great tutor, very patient and understanding."
- Jamie, Minneapolis, MN on 1/19/12
David was a great tutor. He was very patient and was willing to wait while I worked through problems. Reviewed my answers, explained where I went wrong, and helped me to relate my coursework to real world scenarios.
- Paul & Valerie, Minneapolis, MN on 3/6/11
After one session with David my son went from a very poor grade on his AP stats test the week before meeting with David, to a 95% on his AP test 2 days after meeting with David. These are great results!
"Very knowledgeable about stats!"
- Lueveria, Burnsville, MN on 7/5/10
David is truly knowledgeable about all manner of math subjects. He is able to give examples and help apply the information to your pace and level. Very pleasant to work with. I was extremely fortunate to find him. His assistance was a big help. Thank you!
- Staci, Minnetonka, MN on 4/12/10
David has a lot of knowledge about high level math! It's wonderful. And, he's got a gift - by listening to me he's able to determine where the "kink" is in my reasoning so that he can help me see the math problem from and different view and then understand!
I was a little nervous because I need help making the bridge between high level math and the engineering in which it's used, and knowing that David was not an engineer made me a little apprehensive. However, I have found that he is very attentive to my questions and, although he might not be familiar with the engineering concepts, he is able to apply his mathematical skill to my specific engineering situations and help me understand. IT'S WONDERFUL!
I picked the right tutor. David is very proactive also and even went as far as to buy a book that relates high level math to engineering in order to better prepare himself and me.
