Warren David Johnston

This doctor does not care about elderly patients. My Dad was a patient for 20 years. He had a reaction to the vaccine and died of heart failure. Before getting the vaccine he called Dr. Johnston multiple times because he was having an AFIB episode and wanted to make sure it was ok for him to still go ahead. Johnston couldn't even be bothered to call him back. The vaccine elevated his heart rate for 3 days. By the third day, he called Dr. Johnston because he believed he was having a reaction, and again, Johnston NEVER CALLED HIM BACK. Our father DIED the next day. Why Johnston didn't have an awareness and a caution when recommending the vaccine to an elderly patient with a heart condition is truly unconscionable. When he was notified of my father's death, he didn't even have the decency to reach out and offer condolences to our family. A patient for 20 years! That says everything about his character. This dr. needs to RETIRE. His ego and greed is costing lives. Protect your loved ones.

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!!

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.

Dr JOHNSTON is professional, listens to questions & concerns, answers so I can understand. Polite, never rushes me, makes sure all reasons for my visit are met. Staff follow up is excellent. Thank you Dr JOHNSTON!

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.

Excellent service from Dr. Johnston and his entire staff. Fastest response time to queries of any practice I have ever dealt with. Lab results and comments back usually in one day, Makes time to discuss all details and reasons for visit Full write up on appointment finished and available before leaving office. Has my full trust and confidence.

He always spent more than ample time answering all of my questions and concerns and is up-to-date on all of the current research studies and procedures, where other doctors are not. He errs on the side of caution in ordering diagnostic tests to provide himself with more than ample information to diagnose and treat his patients and has a rare combination of both impeccable knowledge in his practice area, and an honest and humble bed-side manner in his treatment strategy.

This office is horrible! If you want a Dr who will take the time to listen to your concerns, so that they know exactly what to test and look for then do not come to Dr. Warren Johnston, as it seems he has a protocol of 2 min with each patient, and will give everyone a stress echo and hear monitor regardless of their symptoms. I had to schedule a follow up visit, 2 months in advance, and go figure, I was running 5 min late, so I had my husband call the office while I was driving. My husband mind

I had to schedule a follow up visit, 2 months in advance, and go figure, I was running 5 min late, so I had my husband call the office while I was driving. My husband mind you was at work, but stayed on the phone for over 30 min and finally, someone answered. He let them know that I thought I was running late but turned out that I was in the building 5 min late. The girl at the desk told my husband, that dr Johnston has over 1000 patients a day to see to and being 5 min late I’d have to schedule for another time to come in and see the doctor. I couldn’t believe the response my husband gave me and if the doctors office would do their job and pick up the phone, then I wouldn’t have waisted an hour driving all the way here to be 5 min late. I spoke to the head manager and they said that the doctor directly refused to see me because of the 5 minute delay. To me this is not ok. Especially, when the doctor gave me a ekg, and stress echo and I received the results, and I have regurgitation in 3 valves and it states that I have an enlarged heart. He even put 2 new diagnosis’s on my chart, one being mitral valve prolapse, and seriously, he couldn’t give me another appointment with 2 min of his time to clarify what was going on with my heart? After arguing with the front desk for about 20 mins, they let me see his medical assistant, who stated everything on the test is normal, even though it states regurgitation and enlarged heart, she said that an exg is not reliable and don’t worry about the diagnosis’s that the doctor gave me as she took them off my medical record. So, would you feel comfortable going to this doctor if that happened to you? Honestly I have had bad luck with every st Joseph dr I have seen and this just tops it off. Make the extra drive to either hoag, uci as it’s not worth going to a doctor and have them treat you this way, when all you want is help. These doctors just care about getting paid, and now, because of him, I need to make an appointment with a brand new heart doctor to re-evaluate what he didn’t do, and really see if I do infact have an enlargement of the heart, as I don’t understand how a twst can come back saying something is wrong, and then the dr places a new diagnosis on my record, and then his medical assistant states that the test was wrong and it’s never right, and they don’t even want to investigate. So, I will soon see who is right here, the doctor, or the test, as I was in a coma 2 years back and that’s why I initially went to see him in the first place due to a enlarged heart, so if it’s been enlarged this entire time in fact, and the doctor has don’t nothing to treat it or prevent it from coming back, then their will be some serious issues here that will later need to be addressed. Seriously, take it from me, get a doctor who actually cares about his patients, or at least acts like he cares and give you the time of day to express what symptoms you are having. Also ensure that the front office is present to deal with, as from what I have learned, is that a front office behavior, is a good indicator of how the doctor was will be l, and waiting for 30 min when they prob have over 30 people working in the office is just a waste of my time and clearly shows, they don’t give a crap about their patients time, or health.

Iris in front is rude and not professional. Especially for a cardiologists office.
