Warren D. Johnston, MD

I am so grateful to Dr. Johnston for listening to my health issues and leaving no stone unturned when investigating my complaints. His care and testing led to a diagnosis of an illness(which was actually in my lungs not heart) that I had had for 2+ years which had been growing and worsening with time. I had seen 2 other doctors multiple times over those 2+ years who were dismissive in my opinion. I am so thankful for his initial dx and referral to a pulmonologist who quickly tested me, gave me a definitive dx and aggressively tx my illness.

Dr. Warren Johnston deserves 5 stars he has always been able to give straight forward answers for every question I've ask or got it for me. This service is the best I failed a stress test in his office he shot me straight in hospital I got 4 STENTS walked 3 days later. I truly believe he saved my LIFE 2 weeks later he said I was strong enough to get to Northern California for my sister's. His staff is awesome too!!

If I could give ZERO stars I would. Doctor Johnston has the worst bed side manners as a doctor and his office is completely unprofessional. I called on a Tuesday regarding heart issues in anticipation of getting in to see him and after 3 calls I got no response so I went to the ER. The next morning, almost 24 hours later, Dr. Johnston's office called me and said Dr. Johnston advised me to go to the ER. Excuse me but if I would have waited for Dr. Johnston's "advise" I would have been dead. They were able to get me in the next day, Thursday only for me to be 8 minutes late after having to wait for the Valet, wait for the elevator, and then wait for other patients to be checked in (which was why I didn't check in until 8 minutes pass my time) for the office to tell me that Dr. Johnston couldn't see me. I AM NEVER GOING BACK TO THIS OFFICE AGAIN THE STAFF ARE AWFUL and so is DR. Johnston! Apparently all Dr. Johnston cares about is a paycheck from my insurance and not about the health of his clients.

Great Doctor with the ability to cut to the chase and give you advise and options. Always feel he has your best interest in mind. The office staff is always very helpful.

I'm very impressed with his performance, it's no complaints about it. I'm flowing up every year with him. The staffs is fine, thumbs up from me!
