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 WWAD World Headquarters in Columbus, Ohio you’ll find a small but mighty team of folks who are lucky to be inspired by a network of walking fanatics and healthcare heroes every day.

Dr. David Sabgir, MD, FACC

Founder, 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, MA

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…

Bryan Romey

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 eight months as an intern, he joined the Walk full-time 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 – Go Bucks!)

Gina DeNucci RN, BSN, CHWC

Walk Advocate

Gina graduated from West Chester University with a B.S. in Corporate Fitness and served an internship at the Pritikin Longevity Center. Her passion for learning how to integrate medicine and physical activity led to a B. S. in Nursing from the University of San Francisco and is a Certified Health and Wellness Coach. She became a Walk with a Doc Coordinator for her local hospital in Boulder, Colorado and quickly realized that her life long dream of helping people improve their lives and well being through movement in a community setting came true. Gina is committed to an active healthy lifestyle and enjoys running, cross-country skiing, hiking, and yoga.

Jessica Agricola

Social Media Coordinator

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.
