Ronald P. Karlsberg, MD

Dr Karlsberg.... Absolutely the best Dr I have on my team. Post 3cbg, 2 endardirectomies renal failure.... He's kept me alive and well for 9 years now. Brilliant.. compassionate.. aggressive treater. I can't thank him enough.

Dr Karlsberg is truly one of a kind! He's an expert committed to life saving research while also a generous hearted with a professional warmth rarely found. We are so blessed to have found him!

I have been to Dr Karlsberg now five times over the past 15 months. He is intelligent and is an expert in the field of cardiology. There is no one else i would trust to give me advise on my heart. Karlsberg is through ,hard working, and very responsible. He returns his messages timely which i greatly appreciate and I have never waited for more than 10-15 minutes before being seen. He is demanding of his nurses & staff and demands a lot of his patients which in my professional opinion is a good thing. I have to say he genuinely cares about his patients. I have decided to become a patient for general doctor services because they take care of their patients so well. My general physician just retired so i feel that i will have excellent patient care with him. Dr Karlsberg is also not overpriced and treats his patients fairly as far as money is concerned. He is the man if you want a physician who knows about the heart. Highly recommend him!! The only negative is that he can be abrupt at times with his patients. I am a retired dentist who also performed anesthesia services for dentists so i know doctors. Dr Robert Nolan West Los Angeles

I cannot stress how much I like and admire Dr Ronald Karlsberg. I was confronting a potentially serious issue which I needed checked out immediately and after a call from my primary physician, Dr Karlsberg saw me as a new patient with zero notice. He conducted two days of testing to make sure he had a complete understanding of what was going on with me. He was kind and understanding and clearly extremely knowledgeable and passionate about cardiology and treating patients. He spent a great deal of time with me and and wife, explaining the test results and reassuring us that we were safe and everything would be fine. He outlined our course moving forward and we left his office with knowledge and confidence. What a godsend. Rather than undergoing invasive, possibly unnecessary procedures had I gone to the ER, he performed exhaustive, non-surgical high-tech scans and tests at the facilities in his medical offices to get detailed diagnostics that those more invasive procedures could not have provided. I highly (and I mean HIGHLY) recommend this cardiologist - not only Dr Karlsberg - but also his excellent assistants, nurses, technicians and support staff. They are gracious, calming, helpful and extremely efficient. Thank you, thank you, thank you.

The most thorough exams & determination of treatment options of any cardiologist I have ever been treated by. Dr Karlsberg is one of a kind, who cares very deeply about his patients. He is by far the leading guru in the treatment CAD.
