I miss Duncan. He was always supportive of me, even though I could be a nuisance at times. He was a good person.

Very sad to lose a great friend. Duncan was a very interesting person. He accepted diversity, and through his medical knowledge and charismatic personality, he understood the importance and value of many people . We were honored to have him in our community and our lives.

Dear Margo, Katie, and Jonathan
I have wonderful memories of working with Duncan at Franklin Regional Hospital over many years. He was always a help when we had some very sick patients.

My sincere sympathy to all of you

When I left I remember how relaxed he made me feel, not your typical doctor's office visit. I am sorry for your loss and the loss to the medical...
