Very thorough, taking time to explain everything in a way I could understand. Never rushed me and was very considerate of my feelings and concerns.
He is a good, thorough doctor that seems to care about me and probably his other patients very much. I'm glad I was sent to him with a referral.
Listened carefully to me and gave me choices in my own treatment.
I believe Dr. Yap will take care of my problem, he seems very positive understand my situation. Hope everything goes well.
Great Doctor
He's really caring and understanding a very great doctor. He also lets you choose a lot of your own goals
Dr Yap is awesome!!! He is caring, listens well, and always makes recommendations based on my individuals needs. When he doesnt know something, he tells you, but also refers you to information or other doctors that can help. He is a great doctor
He is both knowledgeable and exceptionally thoughtful.
He's very friendly great bed side manners and cares about his patients I left my appointment feeling heard
Dr. Yap is incredibly thorough, thoughtful, and caring. He prioritizes listening and including patient's in their care while providing evidence based care. He was clear with education regarding options for management and shared decision making.
Dr Yap is exceptional.
You must ask to see him. He is a people person who took his time listening to me and explained my treatment in full detail. I have already recommended him to my friends and family. He is an asset to the U of U Health.
Very caring and knowledgeable in area of expertise. Felt I was in excellent hands for my health care needs.
Dr. Yap spent time sharing the likely procedures that I will need to go through in videos. It is very helpful.
Dr. Yap really cares about his job and his patients. The visit with him was great and I felt heard and understood. I am excited to work with him to find a solution. The location I went to unfortunately, was very disappointing. Very unprofessional staff. Dr. Yap went above and beyond in understanding our disappointments in areas. None of this disappointment reflects on Dr. Yap. I look forward to working with him.
