UH HOSPITALS AND CLINICS

Dr. Deacon has been a pivotal influence for my overall care. He has been incredibly supportive and genuinely has done all he can to problem solve as issues come up. Having a complex condition that is so rare the research is happening currently which limits the ability of all my providers to come up with a treatment plan that works for a good amount of time. Each provider has done their best including Dr. Deacon. Infact he has been at the forefront of this along with another provider from the hematology clinic. His willingness to collaborate for my best interest is part of what helps me feel confident in his care. He isn't afraid to say I don't know, while still reassuring me that he is making recommendations based off insight and understanding of the overall complexity. I know he has my best interest at heart which makes me feel more open to trying new interventions he offers.

HUNTSMAN CANCER CENTER

I am an MD. Dr Deacon is one of the best physicians I have encountered. He is an excellent listener and he asked good questions to clarify about things I had not considered. He did a thorough exam (something many physicians these days have forgotten how to do). He explained his thought process in detail in a way I could understand and he was patient with my questions. And most impressively he 1. checked my insurance formulary to guide his prescription choice (first physician I have seen do that) and recommended good rx for meds he could not find an equivalent on the formulary and 2. he closely tracked my prior use of biologic medications for psoriatic arthritis that had not been effective to recommend a possible more effective treatment plan and reached out to my rheumatologist to coordinate care plans for the future. Amazingly comprehensive all on my first visit. 10++++
