I went to Dr. Doyle with serious fatigue, stamina, and energy problems that were influencing my work as a university professor. I have improved so radically that friends and colleagues frequently point out my new sense of well being. Living in another area of the country, I make phone appointments as well as travel a great distance since I find his work invaluable. Dr. Doyle not only knows how to target specifically the necessary blood-work but takes the time to truly listen which is unfortunately rare among doctors. In a quiet and respectful manner, he has inspired confidence in me that together we can solve any problem that might come up.
