He was willing to make adjustments to my care that could improve my overall health. Even though this was our first meeting, he spent no time getting to know me and seemed in a rush because he was running behind schedule.

Consulting and Related Relationships

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.

As of 12/20/2018, Dr. Kleman has reported no relationships with companies or entities.
