    Great surgeon! He did my gastric bypass in may 2014 and I've lost over 130 pounds in just 9 months. My overall health has improved.

    I asked doctors who know and they said he was the best in town. I have to agree.

    Doctor Kovacs is that unique blend of a remarkably astute listener, a person of warmth yet…read moreintelligent intent, and clearly a passionate and gifted clinician. I am an "old guy" and been through a few hoops. I have worked in a fair number of hospitals and know the medical field rather well over a 50 year period. Kovac's has what so many have lost: he is curious and willing to connect the dots between seemingly quite separate phenomenon and he will share his views and consider options with you. He is also highly skilled. His was the third colonoscopy I have had and he did it so quickly and effectively I really have no memory of that. Here's the scoop: visit him and judge for yourself.

    Doctors like this is why I am disabled. He seems to have worked for most people. Probably because…read morethose patients where easy for his outdated knowledge. His bloated and fetid ego could handle the easy stuff, kids gloves for the little man. He sat there, almost didn't say anything, gaslit me and straight up lied (head so far up where the sun don't shine his little overly paid world probably couldn't comprehend). He didn't even say goodbye at the end of the appointment, just scurried out the door leaving some flakes of his chitinous hide sullying his floor. Guess his issue is I have more than one rare disease and I was looking to get checked out for a third. He acted like a rare disease specialist, talked over me like I didn't know what I was talking about. I listened to him respectfully, as you know doctors "do no harm" and the such. When I got into the car I immediately looked up the research papers I have saved on my disease and yes, sure enough, he was wrong and spewing outdated data and ignorant "facts". Technically one of my diseases was "cured" in 1940's and very little research went into it. He was thinking of the papers that came out in the 80's. Wild. Couldn't maybe pull something up more recent in your mind before punching down? I went without a diagnosis for 17 years, hence why I am disabled. If doctors like you didn't exist I would be living a much different life. There are more recent papers, much more recent. There is a more research now on how if your have one of the diseases I have, you have a much higher chance of getting another one that I've also been diagnosed with. Maybe you need to go back to school doc, you don't seem too well. My poor niece is in the same boat. Early 20's and has a full time care taker. Has a couple of the same rare diseases I have. But maybe in little Brent's mind that's not possible. I went to a gastro that took out a polyp, It is a sign of one of the diseases I have but they missed it. They didn't care about providing any information or answering any questions. Just in and out, charge my insurance. A mill. I said to Kovacs "Well they missed that". Poor little Kovacs got offended that I guess I didn't talk about his "college" in the highest regard when they can't do there job. When they're busy filling their pockets full of cash harvested from the sick and ailing. The California way. I'm once again glad you seemed to have showed some humanity to most of your patients. But Brent, I've seen so many doctors I lost track. I will say it's got to be 80-90% of you failed me. Gaslit me. Called me a liar. Made up some fantastical ideas of why I was experiencing my symptoms. I would believe you all. Why shouldn't I? Then say I would start puking blood and there must be something wrong. Rinse and repeat. I had to dog walk doctors to each one of my diagnosis'. Instead of blaming the patient Brent for shining a light on a dark spot of your knowledge maybe theirs something wrong with the system. You think Brent? Or is science by its fundamental nature set in stone, never to be questioned or changed. At least since when you went to school so you don't have to worry about updating your knowledge right? If you take all the rare diseases combined and lump them all together, they're not so rare anymore. There are forums and forums filled with people like me who doctors wouldn't listed, cast aside to die in the gutters. Being chased away and to try dangerous and untested medicine and treatments. I had a life to live and you took that away. You and the system. There is something wrong with the system and your too ego driven to see past your own fecal encrusted nose. I also have medical cPTSD, so thanks for bringing that up as well. Guess what Brent? Ive been tested 4 times for one of my rare diseases you wanted me to have tested again, all positive. I've been tested three times for another and the disease I was coming to you for a possible diagnosis? I have that as well. I went to a real doctor though in LA who you know, maybe kept up with the literature before stating some ignorant bile.
