in Lancaster, CA |
I have been privileged to have Dr Yadegar as my physician for more than ten years. Having had very negative experiences with surgeons in the past, I was thrilled to finally have someone in my life with so much compassion, consistency and integrity. Several years after my gastric bypass, I petitioned my medical provider to allow Dr Yadegar to perform another, unrelated surgery. I didn't trust anyone else. I am grateful that he and his staff continue to provide me guidance and support at anytime.

Dr Yadegar is the best Bariatric Surgeon. He has a great knowledge of his specialty and explains it to his patients in easy to understand terms. Dr Yadegar is a very caring doctor that makes himself available to his patients. He's available to patients to help them to meet their weightloss and health goals. He doesn't stop that caring once you've reached your goals but he's also available if you get off track and need further help to get back on track! He's AWESOME!!!

Dr. Yadegar is the very best doctor I have ever dealt with. He's tough, but loving because he actually cares about your well being and knows you by name. He hires staff members that are in line with his goals. He is incredibly skilled. The only downside is that you often have to wait well past your appointment time to see him - but have no fear, it's because he's spending quality time with patients and will do the same for you. He's worth the wait!!!!

I love Dr Yadegar! He was amazing! No question was too big or small for him to go over with me. He spent so much time with me during each of my appointments. I never felt rushed out.
