What else would you like to say about your experience?
Dr Yagan is probably the most personable and caring doctors that I have ever had the privilege of seeing! I have numerous health issues and was given a limited amount of time to survive but Dr Yagan said we were not going to allow that. He consistently sets new goals for me to achieve in life and is always involved with me and things that I want to be here to see in my future! He is always optimistic and supportive of what is going on with all of my medical needs and progress! He has been the greatest support a lot of times when it seemed like every other doctor was almost ready to have me just give up and except my illnesses! With him as my doctor, I have always felt like I have a reason to keep fighting no matter what! I have only ever had one doctor other than him that made me feel like a friend that they were going to always fight to keep alive and not just a patient! I feel like I owe him the last 6 years of my life!

Dr Yagan is the best medical doctor a patient can ask for. He probes with questions to set the correct timeline of health events to understand all that has occurred and how to go forward. He listens to all questions & comments, and willing converses to fully understand ones health experiences. Then uses all of that to set a path forward with his outstanding medical care. He is compassionate, professional, personable. A true blessing to have Dr Yagan leading my health care.

A great experience. My wife and I admire the way he practices medicine. He asks appropriate questions and responds with one or more actions o support his recommendations. He doesn’t miss a beat, quickly tells you if he doesn’t approve of a particular suggestion you make. He is the best I have at the moment.
