Emergency Medical Services

Mike Oaster 

EMS Full-Time Faculty 

I graduated with an M.B.A. in Health Care Management from Indiana Wesleyan University and a B.S. in Elementary Education from West Chester University. I also earned my paramedic credentials from St. Joseph Hospital Paramedic Institute in Lancaster, PA. Over the years, I have cultivated an esteemed career, predominantly focused on medical education and management. Starting as the Program Director at the Albert Einstein Medical Center in Philadelphia, I took on pivotal roles in paramedic and EMT courses. I then served at Harrisburg Area Community College in Lancaster, PA, as an EMS Instructor. My dedication to education continued at Sinclair Community College in Dayton, OH, where I am currently a Professor of EMS. My contributions here, from developing curricula to mentoring new faculty, have been recognized through multiple accolades, including the Meritorious Teaching Award received consecutively from 2005 to 2023.

However, my expertise isn't limited to the classroom. My managerial acumen shines through in my roles at various emergency medical service organizations. Serving as the Director of Operations at White Rose Ambulance, I oversaw a bustling operation handling over 25,000 calls per year. My responsibilities spanned from the day-to-day management to employee performance development and public relations. Similar impactful roles were played at the Lancaster EMS Association, serving as Administrative Supervisor after starting there as a Paramedic.

Beyond my full-time positions, I am actively affiliated with the Sinclair Community College EMS Department's and Fairmont High School's Fire Science Advisory Boards. Internationally, I left my mark at the Narenthorn Center in Thailand, dedicating three summers to impart EMS and Instructor courses across the nation. I also contributed as a textbook reviewer for the National Association of EMS Educator’s Foundation of Education. All these experiences have honed my ability to foster a diverse, equitable, and inclusive learning environment, cementing my reputation as an influential figure in EMS education and management.
