He loves his patience and he is humble and besides a great doctor a good man.

This doctor may be great, I couldn't tell you. In an attempt to avoid leaving the area for…read morecosmetic dermatology services, I called today to ask about the cosmetic services offered (as noted on their website) and the very rude and incredibly short receptionist said, "yeah he does cancer stuff so he can do that too." What kind of answer is that? Why would you have a person answering the phone who does not know which services are offered? Pathetic. I asked for someone else who might be able to answer my specific question and was met with the same dismissive response. If I can't even get a simple yes or no answer regarding whether or not this doctor performs a procedure that I intend to make an appointment to receive, then why would I make an appointment? The receptionist sets the tone for the level of professionalism of an office and this person is deeply lacking the skills necessary to represent a professional office. After reading the other reviews about the customer service, one dating back to 2012, I can only infer that the entire business is equally as unprofessional. Immediately after this ridiculous exchange, I called another local dermatologist's office; my question was immediately answered in detail, and I am scheduled for an appointment in a few days. Take note.

We love Dr. K! He literally saved my life. I was in his office while he was removing a melanoma…read more(the deadly kind of skin cancer) from my husband. I was wearing a skirt and he noticed a mole on my leg, told me to come back for an exam. It was positive for melanoma, and a bit more serious than my husband's. Had he not noticed it and removed it, I'd be dead. Really. We both still see dr k at least a couple of times per year - he's a good guy! I looked at some of the other reviews and am wondering why you go to the dermatologist, to chat with the office staff or to receive medical attention? I see him to deal with a life threatening cancer. He answers every question I ask, tells me what all of the medical terminology means, and always spends a lot of time with me, reviewing every mole. I've been on the end of his scalpel many times, and I trust him absolutely. Oh, I've been in the office probably at least a dozen times, I've never met a male PA, so I'm wondering if that review is even for this office (our billing is fine, they send a bill, I pay it). After all of these times, I don't know the office staff's names (shame on me, I guess), but I find it surprising that people are mentioning a receptionist of a doctor they saw once...? So - pros: caring, intelligent, good listener, solo practitioner, you go there, you see Dr Kamath. He calls me when test results come in, and explains everything really well and has been known to nag me when I get behind on my regular visits. Cons, the robo dialer that confirms your appointment mangles his name, I hate the paper gowns, has been known to nag me when I get behind on my regular visits. (Ok, the nagging is a pro, but it cab be a pain when busy - oh wait, it's a melanoma check, guess I need to stay on that) Unfortunately, during the time I've been treated for melanoma, I have lost three people I knew to this horrible cancer. Please stay out of the sun and wear a hat!

In the first 2 Visits through his knowledge and expertise, he was able to identify the issue right away! It was actually pretty amazing to see how fast he found it.

I'm so grateful of his help because it has changed daily life for the better for me, and this is just one of the things he has helped me with among many other things. His staff is a very friendly and professional group of gals and help in any way they can to make you feel comfortable and overall is just a pleasure to be around and a great team!

A Life-Changing Experience with Dr. O'Connor…read more I have been a patient of Dr. O'Connor for many years, but I recently experienced firsthand why his specialization in back pain is so legendary. After a simple move--picking up a pair of pants--my back went out completely. I was in excruciating, incapacitating pain. While sitting offered some relief, the transition to standing was unbearable; it felt like my whole back was lighting up. I reached out to Dr. O'Connor, and he got me in quickly. Using his years of experience and specialized tools, he worked on my back--bending, twisting, and carefully adjusting my spine. After about an hour of his targeted treatment, the pain was simply gone. It was absolutely amazing. This isn't the first time he's saved me, but this lower back incident was the most severe. If you are suffering, you don't need to rely on painkillers or live in misery. Dr. O'Connor has a plan for relief. He is a true blessing, and I cannot recommend him highly enough!
