Our Patients Say It Best
“Dr. Kim handled my very complicated situation with excellent decisions, excellent surgical skills, and excellent communication. He worked very hard and responded promptly to our questions, which saved us a lot of worries.. If you want the best possible outcome from a surgeon who treats you with respect and sensitivity, he’s the best.”
“I have had nothing but great experiences with Dr. Kim. A little over a year ago I was diagnosed with anal cancer and Dr. Kim performed the surgery to remove the mass. He also installed and removed my “port” in my shoulder for the chemo and also recently did a colonoscopy on me. So I have had four (outpatient) minor “surgeries” or “procedures” with him in the last year. So far I am still cancer free. I have found him to be skillful and compassionate. He has become one of my favorite Doctors.”
“I met Dr. Kim at John Muir Hospital after being diagnosed with Diverticulitis and the recommendation of surgery by another surgeon. On my second visit I was introduced to Dr. Kim and both my wife and I felt very comfortable with his knowledge, diagnosis and bedside manner. He has been on call to answer my questions and has seen me on 2 extra occasions. I am comfortable with surgery in his hands and expect a complete normal recovery.”
“Thank you for your kindliness and professionalism. you did put me at ease, I didn’t know what exactly I was facing. for a busy person like you two phone calls in one day. I’ll give you from 1 to 10… 100/10! Thank you, you’re in the right profession. Also, having your nurse, who is just as kind and gentle as you, I’ll never be in better human hands. Thanks.”
“I would like to extend my sincere thanks to you and your staff for your advice and care you have shown to me. I was so touched by your kindness and concern for my well being. You and your office staff have been so understanding. In my mind, you are not only an excellent physician, but a kind person who sincerely cares about his patients. you are greatly appreciated.”
“Dr. Kim not only is an excellent surgeon who quickly scheduled an urgent surgery for me, he also put my mind at ease about the upcoming operation.”
“Amazing surgeon, hands of an angel. Very supportive. Explained procedure. Gave me options whenever he could. Great surgeon!”
