The Session was a Great Success

Ari effectively balances the level of his explanations with the knowledge of his clients, be they beginners or professionals alike. More importantly he really understands his client's problems and supports others to achieve successful outcomes through a variety of channels. I did his online courses as well as a one to one session online. He organized and explained everything in advance to ensure that the session can start on time, and the live online session was a great success. His professionalism, work ethics and enthusiasm are exemplary, his knowledge is extensive, and above all his personable and kind manner set him entirely apart. I would be more than happy to work with Ari again.

Allan Miller, Ph.D. R Trainer and Consultant

Knowledgeable, well-organized, patient, and clear!

Ari recently conducted his workshop Mapping Open Data in R for the Berkeley R Meetup at U.C. Berkeley. The workshop was a tremendous success.

Ari is a highly skilled and effective presenter. He is knowledgeable, well-organized, patient, and clear! His workshop examples and supporting materials are excellent. Participants came away from the workshop with the basic skills necessary to start working on mapping projects on their own. The response to his workshop by participants was universally positive, several have requested a follow-up session.

If you have a mapping project and need training or technical assistance, I highly recommend Ari's workshop and services for your organization.
