Meet the Team!

Walk with a Doc is made up of healthcare professionals and walk warriors around the globe who are driven by an earnest belief that walking is the miracle drug destined to change the world. At the headquarters in Columbus, OH you’ll find a small but mighty team of folks who are lucky to be inspired by Walk with a Doc’s network of walking fanatics and healthcare heroes every day. Head to the “Our Docs” page to meet our healthcare providers, the “Our Walkers” page to hang out with our walkers, or learn more about our headquarters team below.

Dr. David Sabgir

Founding CEO; Board President; Cardiologist

David went to Miami of Ohio for undergrad; Medical College of Ohio for Medical School; and served his internship, residency, and fellowship at The Ohio State University Medical Center. He practices cardiology full-time for the Mount Carmel Health System and serves as their Medical Director for Cardiac Rehabilitation. He lives in Columbus, Ohio with his wife Kristin and two children, Ally and Charlie.

Rachael Habash

Chief Operating Officer

Rachael graduated from the University of Michigan (Go Blue) with a B.A. in Psychology. She then served in the United States Army as a Medical Service Officer prior to earning her M.A. in Counselor Education at OSU. The prospect of utilizing her professional experience as a leader, resource manager and program innovator while encouraging healthy physical activity, is what initially attracted her to WWAD. Now that she better understands the impact of the miracle drug (walking) and vast number of people served by WWAD, she’s hooked! It’s almost as addicting as her girls’ (Grace and Nora) smiles…

Jessica Agricola

Walk Program Manager

Jessica graduated from The Ohio State University with a B.A. in English in 2015. During college she worked as an outdoor educator, constantly exploiting her position to spread the health. When she realized she could do that without wearing the same outfit in the woods for two weeks, she found Walk with a Doc. She now gets to wear clean clothes most days.

Bryan Romey

Walk Program Coordinator

Bryan was lucky enough to get paired with Walk with a Doc for a class project during his final semester at The Ohio State University in 2017. He graduated with a B.S. in Health Sciences and was thrilled to find out that an intern position had opened up at WWAD. After 8 awesome months as an intern, he joined the Walk as a Program Coordinator. When his wife Shannon asks what he did at work that day, his answer is always the same: “I helped change the world!” Outside the office, his favorite activities are basketball, golf, tennis, snow/water skiing, running (and walking), and even corn-hole (2014 OSU intramural champion right here – Go Bucks!)
