Biographical

I am an Ohio native, being raised in the small farming town of Forest, Ohio. It is with great pride that nearly my entire training was in Ohio, and I have dedicated my career to caring for those who call Ohio home. Thus, I have committed my career to maintaining the highest level of care for my patients and committing myself to the service of The Ohio State University Wexner Medical Center, so it can achieve the level of sustained greatness that I know it is capabable of.

Since I joined the OSU faculty in July, 2008, my goal has been to achieve success in the three pillars of academic medicine, teaching, research, and clinical practice. However, the one area of focus of my 9 year career as an assistant professor, has been to attain the highest level of clinical excellence. I have sought this through maintaining 90% clinic effort. This has been primarily through direct patient care, but also through a vast array supporting the mission of the division, department, medical center, and the State of Ohio.

On a personal standpoint, I consistently attain patient satisfaction scores greater than 99% and my demand for new patient appointments, results in a wait list of over 6 months. While this is the most satisfying success any physician possess, there is a special satisfaction in the vast success I have achieved in my clinical service to the division, department, and medical center. I successfully started the Endoscopic Ultrasound program at OSUWMC in 2008 which is now performing over 1500 EUS procedures annually, bringing notoriety and referrals to the medical center.

In 2013, I was appointed medical director at Stoneridge Endoscopy Center, during a period when volume was so low, serious consideration was given to closing the facility. I worked aggressively to resurrect the volume and maintain a high level of safety, and in 2015, we successfully achieved a volume equal to past peaks, with continued high safety and high patient satisfaction scores.

In 2014, based on these successes, trust was placed in me to be appointed the director for outreach for the division. In this role, I have led the effort increase referrals through a balance of meet-and-greet sessions, lectures at regional health facilities, and an annual division led conference on high value care for the PCP.

In the last two years, my successes in the division and my successes with collaboration throughout the medical center, led to my successful election as Chief-of-Staff for University Hospital, as well as recognition with Faculty Achievement Award and the Exceptional Physician Peer Award in 2015.

In summary, as the following Dossier will attest, I have attained great successes in the realms of research and education, but the basis for my identity and success at OSU has been in with a focus on clinical excellence.
