Dr. Castle is a Board Certified Dermatologist with over 22 years of practice experience.  He is a graduate of Wooster College in Wooster, Ohio and The University of Osteopathic Medicine and Health Sciences, Des Moines, Iowa.  He completed his dermatology residency at Fitzsimons Army Medical Center in Aurora, CO where he was Chief Resident.  Dr. Castle completed his fellowship in Mohs Surgery in 1999.  He was also a Major in the US Army Medical Corps on active duty from 1987 to 1996 and US Army Reserves from 1983 – 1987.  In 1992, Dr. Castle was awarded the Meritorious Service Medal.

Dr. Castle is a Fellow of the American Academy of Dermatology and the American Society for Mohs Surgery.  He is also a member of the Associations of Military Dermatologists and Military Osteopathic Physicians and Surgeons. He was recently awarded “Best of Greeley” in November 2016 for his dermatological services.

Dr. Castle treats all general skin problems including acne, eczema, psoriasis, skin and nail problems.  He believes in the “holistic” philosophy in medicine.  He prides himself on spending adequate time with patients to understand the true cause of medical disease and to get to know each patient as a person, and to have them feel at ease.  Medical illness and the patient’s wellness is closely tied, not only to the structural integrity of the muscular-skeletal system, as is part of the Osteopathic Theory, but also to the patient’s emotional state and mental health. Dr. Castle enjoys understanding how medical illness and skin disease is related to stress, nutrition, and an overall feeling of well-being. He believes patients do better and respond to treatment more effectively when they feel confident that their physician sincerely cares.
