I con­sid­er it an hon­or to be a trust­ed health­care provider, per­son­al­ly I see it as a priv­i­lege to care for the patients in our com­mu­ni­ties. I strive to ensure every patient receives the same qual­i­ty of care which I have come to expect for my own family.

"Dr. Van Osdol was fantastic. I feel that he looked over my records before my visit, he looked deeper during my visit based on our conversation. He made a true effort to help me find some answers and determine what is happening following the Moderna booster. I absolutely respect a doctor who has an attitude that while we may not currently have answers, we will strive to find some. Very knowledgeable and included me in the decision making process, asking if I felt comfortable with the plan of attack. I value a doctor who treats you as a person and values my input."
