Leadership

Robert J. Trenschel, D.O., MPH
President and CEO
President & Chief Executive Officer, Dr. Robert “Bob” Trenschel brings nearly 20 years of healthcare and medical management experience to Onvida Health. His strong focus on population health emphasizes the hospital’s responsibility to utilize its resources in a way that benefits the overall health and well-being of the community and region.
Creating a system that promotes the practice of caregiving with ease, supports and rewards staff and ultimately provides the best patient experience is a triad of success that Dr. Trenschel believes is the core of the leadership team’s daily work.
