Physician Assistant, Dan Cadwallader, PA-C
Member: American Academy of Physician Assistants, AAPA Member, Society of Physician Assistants in Pediatrics

While spending the summer volunteering at a missionary hospital in Limbé, Haiti 25 years ago, Dan had the unique opportunity of experiencing firsthand the enormous impact a group of dedicated people could make in the lives of others, as well as their own. After that summer in Haiti, he devoted himself to becoming a Physician Assistant and soon found himself at one of the country’s premier PA programs.

Just prior to completing the program, he returned to that same hospital in Haiti. This was during the late 1980’s and the AIDS epidemic had exploded, as did Haiti’s tumultuous political situation, heaping more suffering on this desperately impoverished nation. “In spite of these hardships, I found that the hospital staff and its international volunteers of doctors and nurses remained steadfast in their resolve to improve an impossible situation. This dedication left an indelible mark on my heart and shaped my understanding of stewardship. Now, twenty years later, I feel I am part of another tremendous organization at Children’s Medical Center of Tucson. Here again are a diverse group of individuals working as a team to serve our community’s children.” Dan feels that being given charge of that which is most precious to someone – their child – “is the highest honor and a monumental responsibility.”

Dan enjoys spending time with his wife and son. “The three of us love to play, read and ride bikes.” He also enjoys writing and hopes to one day publish several of the children’s books he has written.
