David Glass, DO ’22, RES ’25, started at Philadelphia College of Osteopathic Medicine in 2017. Eight years later, he is preparing to graduate from PCOM’s Graduate Medical Education program.

Quality and compassion have guided his journey from Biomedical Sciences student, to the Doctor of Osteopathic Medicine program, to residency in Internal Medicine. From the start, he was determined to make a difference. As class chair during medical school, he became a crucial link between students and faculty, ensuring academic success and voicing student concerns.

He worked with faculty to create interactive and mental wellness events, study sessions, and other opportunities for classmates to connect and grow. His knack for problem solving extended to working with PCOM technology specialists to resolve tech issues during and after classes to help ensure a seamless learning experience.

Leadership became a hallmark of his residency as well. He served as intern GME representative and later as a chief resident, roles in which he scheduled academic sessions, advocated for residents’ well-being, and facilitated vital communication between administration and residents to improve academic and clinical skills.

“I helped also with establishing a Quality Improvement project, expanding research opportunities, and helping faculty integrate Internal Medicine residents at the Cambria clinic site. I promoted the health and wellness of the internal medicine residents,” Glass said. “Overall, the leadership positions I have held have been very meaningful because I know I made an impact on my fellow medical students, residents, and faculty, which will help promote and continue to improve the future for them at PCOM.”

Next month, Glass takes the next step in his career, beginning a fellowship in Obesity Medicine at Northwell Health in New York. He plans to specialize in Gastroenterology in the future. Outside the hospital, he finds renewal in travel and adventure, such as trips to Switzerland, where he has hiked the Alps.

Daniel Parenti, DO ’87, chair of Internal Medicine and program director of PCOM’s Internal Medicine residency, has witnessed Glass’ growth firsthand.

“I first met him when he was in charge of the lecture hall audiovisual equipment during my pulmonary course,” Parenti said. “He has been an outstanding resident, clinician, teacher and leader.”

To those following in his footsteps, Glass offers this advice: Always be honest and respectful of others.

“Always be diligent and conscientious with your work, as it not only reflects on your quality as a physician, but it can impact patient care. Lastly, have fun,” he said. “Residency can be grueling, but if you set yourself up for success in the beginning, you can overcome anything.”
