Residency Program at Saguaro Dermatology

Saguaro Dermatology is proud to support our community through our partnership with other healthcare institutions including HonorHealth’s Dermatology Residency Program. Starting July 2022 Saguaro Dermatology’s Dathan Hamann, MD and Carsten R. Hamann, MD, PhD joined the HonorHealth Dermatology Residency core faculty. Additionally, Dathan Hamann, MD now serves as Associate Program Director and Carsten R. Hamann, MD, PhD serves as Director of Research. Saguaro Dermatology has always prided itself on its commitment to education and to training future board-certified dermatologists. This endeavor has primarily taken place through our partner clinic, Contact Dermatitis Institute, but we are proud to extend this educational commitment to Saguaro Dermatology itself.

What does this mean for my clinic visit?

Our dermatology residents are full physicians who have completed medical school and at least one year of training in internal medicine. They are capable, intelligent, excellent physicians, in training to become full board-certified dermatologists. If you are scheduled with a resident physician they will be your primary physician but with close supervision from Dathan Hamann, MD or Carsten R. Hamann, MD, PhD.
