    I called the number provided, and an AI voice Attendant answered and when I asked to speak to the…read morefront desk, it hung up on me 4 times. The fifth time I called, it connected me to a live person, who was able to give me the email address I asked for. Also, I was informed that Blue Coast Cardiology does not have a website. This is fine. However, it should be shared in a simple statement, on search engine sites like google, Facebook and others, that their information, that they do not have a website, and that they have an automated voice front desk. The automated voice, should give the address, and the option to speak with a live person. Their doctors are very good.

    The office staff was really kind to me. I really appreciated that. The TV in the waiting room was…read moresometimes too loud. They had the nature channel on so sometimes it showed animals attacking each other which was a little unpleasant. The waiting room itself was nice. Dr. Bui was really friendly and kind on the first visit. On the second visit, not so much. She was brutally honest about what she thought about me. On one hand, I could appreciate her honesty, but she was very wrong in her judgment. I had a test done that proved I had a medical problem. She told me that she took back what she said about me. That was really nice of her. On the third and fourth visit, she was better. I don't dislike Dr. Bui as a person, but as a doctor, I think she should have not been so quick to judge. Or at least she could have kept what she thought to herself and let the tests show her what was going on. The second visit was just awkward and felt weird. I would not recommend her to family and friends because I don't think they would like her personality. If she would have said to them what she said to me, they wouldn't have gone back for more testing and treatment. I don't think this doctor is for everyone. You need to be persistent when you know something is wrong despite what the doctor may say.

    This is my first time meeting this doctor. I don't think he was Dr. Chavira. I had been looking…read moreforward to this visit, to help with the edema in my legs. He came in, shook my hand & started talking 100 miles an hour. I understood maybe 1/4 of what he said. The nurse/person on the computer was asking me questions & he was dictating, & she was typing really fast. He was standing the entire visit. She said to him that I was having trouble breathing, he said "the reason she's here is because of the swelling of her ankles". Says he "can already see the problem, she's obese". I told him that my daughter is a doctor & had written notes & a video for him. He said, "I don't need the video, you're here now. I'll just look at your ankles". I played it for him anyway. He kept rattling off words to his nurse, "there's nothing wrong with you, but I just want to order some tests." He continued listing tests. "How tall are you?" "5'5" I think". "You're fat. You're just too fat. You just need to lose weight. Why don't you lose weight." I try to speak - "I've tried. Since lithium & levothyroxine I've gained about 30 pounds". "Haha! That's nonsense. Thyroid medication for *hyper*thyroidism - you lose weight, not gain. (I'm *hypo*thyroid)You are LAZY!!! (Doing everything I could not to cry, I said, "I'm not lazy"). "And you are probably drinking too much soda." (Points to my water bottle) And, I know they say 8-10 glasses of water - but that's nonsense! You're drinking too much, which is why your ankles are swollen. (I don't drink soda. Only water, + two coffee, two tea daily). "I'm going to order some tests & bloodwork. They will do them now & then I'll wash my hands & come back". Then he runs down the list of tests. "Treadmill?" I say. "Yes, is there a problem?" I told him "the past few times", he finished my sentence, "you take that pill?" "Yes"- I said. "No! Can't you walk for 30 minutes? See, you're lazy! You're obese because you eat too much & don't exercise enough. It's not complicated. Why don't you lose weight? Another option is gastric bypass." The nurse/person told me to wait out in the waiting room & they will call me, when they're ready for me to take the tests. I said "ThankYou" & I just kept walking to the elevator & to my car. I sat in my car & cancelled my appointments for the rest of the day. Every single one of the nurses was "obese". Doesn't make sense. He's supposed to be a specialist in edema? Hard part is, I can't shake off feeling like dog poop. That will be with me for awhile.And, I really am concerned about my legs. But, I'm not going back there. Every doctor says something different : Dr. Marfori - "Would you rather be thin & unhappy"? (Side effects of Lithium & Zoloft). Nutritionist : "6 small meals a day to prevent low blood sugar". Gonzales : Didn't say. Dr. Shad : Didn't say. Allergist : Lose 20lbs.

    I went to North Coast Cardiology for routine surgical clearance and had a very poor experience…read more During the visit, I felt repeatedly pressured to undergo additional testing. For the first test, I was told, "Your insurance will pay for it, so you might as well do it." I agreed based on that representation. A second, much more expensive test was presented in a way that relied heavily on fear and uncertainty. After asking the doctor several times whether it was truly necessary, and finally asking whether he would personally spend $1,000 on it under the same circumstances, he said no, so I declined. Despite that, the office later scheduled me for the test I had declined. Worse, the first test was submitted to insurance in a way that resulted in a denial, and I was billed for the full amount. I have called and emailed Emma in billing multiple times to discuss the charge, but no one has responded. Between the pressure to purchase additional testing, the incorrect scheduling, the unexpected bill, and the complete lack of follow-up, this was an extremely disappointing customer experience. There are many cardiology practices to choose from, so I am sharing my experience to help others make an informed decision.

They even took my mom's blood pressure manually without being asked, knowing the automatic cuff can be uncomfortable. They tracked down all her records and took a real interest in her as a person, as well the specific nuances of her as a patient. We feel so fortunate to have found her. Highly recommended!
