Dr. Brian Leish, MD

Dr. Leish has been my primary care for at least 20 years. He's an outstanding, knowledgeable, and caring physician. I've referred several friends to him over the years. His long time assistant, Elsa, is also excellent and very helpful. They're both very responsive if you leave a message for them. His staff values his working patient's time with efficient appointment booking. They don't overbook and keep you waiting forever for your appointment like some other doctors do.

Visit went as expected. Short, sweet, and concise. It was nice to joke a little bit too with Dr. Leish.

Because of the need to find a new doctor I was very pleased to have found Dr. Leish. Our meeting was informational and I left feeling positive my health care was in good hands.

Dr. Leish is thoughtful, knowledgeable, skilled, courteous...everything I look for in a healthcare provider. Time and again he has put me on the path to wellness.

Dr Leish is my PCP . I have always been able to book an appointment with him when needed in a timely manner. He is a kind and caring physician who listens to his patients and treats them with utmost respect. His assistant Elsa is outstanding. I highly recommend Dr Leish as a primary care physician .

Dr. Leish has been my doctor for 20+ years. I always go back to him whenever I can.

Experienced, knowledgeable, easy to get an appointment, short waiting time, takes time with patients, keeps good records, followup after tests, good diagnosis.

My wife and I live in NV and have experienced challenges finding “good” healthcare providers; in particular, an endocrinologist. Neighbors and others have mentioned the same dilemma. So, we decided to try CA doctors. After some research my wife scheduled appts. with a highly-rated specialist and GP, Dr. Leish, affiliated with the same Med Group. We are extremely happy with the decision. Dr. Leish was very thorough in performing comprehensive exams for us. The lab is located right in his office and he provided blood test results the same day as the test (that’s never happened before). He personally called my wife prescribing another test to address a potential issue. This new test can also be performed at Dr. Leish’s location (very convenient). Dr. Leish is succinct and thorough, as I mentioned, sprinkling in some subtle humor. The office staff are all very friendly and helpful, too. We feel very fortunate to have found Dr. Leish and highly recommend him.

Dr. Leish is very thorough and professional when he performs his medical services. I feel very fortunate that I have benefited from his services for the last 30 years.

I was able to get an appointment quickly. My regular doc was out that day. Need a preop check and he was very patient and thorough. I appreciated him being there despite the fact it was a holiday. Thank you

Highly recommend Dr. Leish. He is exceptionally caring and competent doctor. I have been communicating my symptoms via patient portal and he responds on the same day. His diagnosis have been accurate and treatments have been very effective.

Extremely happy with Dr. Leish. Very knowledgeable on many facets of the body. Been seeing him for about 15 years now. At the time wasn't seeing doctors but a back injury snowballed into other complications. Went through about 5 doctors prior to him and am currently seeing him.

My recent visit to Dr. Leish was a follow-up to a hospital ER A couple of days prior. What was significant to me at the time was that he was willing to wait for me when my transportation was delayed. While we did not have the time to cover many areas, he most graciously followed up on the hospital visit and took steps to make my arm feel more comfortable. He is perceptive and kind as is his staff. They are a bright spot in the medical community of Southern Orange County.

What a great manner Dr Leish has! So pleasant and really listened to me. I felt so glad to see him, I really felt reassured I was in the right hands. I found my primary care physician for sure!!

Thanks so much Dr. Leish for everything. God bless..:-)

He is a great doctor and very kind.

No Bedside Manor. Very pushy in his beliefs and came across as cold. Will not be returning to him

I have complete trust in Dr Leish.

I have been a patient of Dr. Leish for a few years. I appreciate his knowledge and understanding of my personal health. I would highly recommend him to anyone who needs that special touch of a good doctor.

Dr. Leish is the best doctor I have worked with. He knows his stuff. I trust his decades of experience practicing medicine. I sleep comfortably at night not having to second guess his diagnosis and counsel he provides.
