Mark Yarosz, MS, PT

Site Director
Mark Yarosz, MS, PT graduated from the University of Indianapolis in 1999 with a master’s degree in physical therapy. He worked as a physical therapist and rehabilitation team leader for five years until he was approached by Dr. Buynak and asked if he would be interested working in clinical research. Mark found his passion and has been working in clinical research ever since. He worked for 15 years as Site Director of Northwest Indiana Center for Clinical Research/Buynak Clinical Research which became part of Velocity Clinical Research in early 2020. Mark started working in clinical research because it was an exciting new challenge in a field where he could continue making a difference in the lives of patients. During the past 15 years he has been fortunate to be a small part of many clinical trials that later went on to improve the lives of thousands of people. As part of Velocity, he looks forward to growing his site to expand clinical trials access for the residents of Northwest Indiana and surrounding communities. Mark is originally from Pennsylvania and is an avid fan of the Pittsburgh Steelers. He has been married to his wife Jill for 13 years and they have four children and a very loud hound dog. Mark dreamed of becoming a Paleontologist when he was young and now loves fishing, gardening, hiking at the Indiana Dunes lakeshore, rock collecting, and metal detecting. He also enjoys vacationing in Maine, Door County, WI or at the Outer Banks of North Carolina.
