Dr. Guan is the absolute best. I can’t say enough about how caring and thorough he is. These days it is so difficult to ever get a hold of your doctors, and yet he is always responsive and supportive. He also has a wealth of knowledge, experience and passion. He truly listens and always strives to find the most effective and innovative solutions. I have so much respect and appreciation for him, and I am a difficult patient with some serious issues. I have never had a GI doctor who I have felt has given me better care. I recommend him most highly, and I have referred my family members, who now are patients of his as well. That is my highest compliment because I trust him with not only my care, but the care of my loved ones!
Very timely and personable. Easy to understand and talk to and he listens very well.
