This dental office really let me down in that they tried to push a medical intervention without my…read moreINFORMED CONSENT. They were also brazen and disrespectful in doing this! Dr. Calvin raised his voice at me for not agreeing to his intervention! Such an action reveals their complete and utter lack of compassion and respect for their patients and violates the fundamental tenets of medical ethics. In addition, Dr. Calvin is not a licensed physician, and the intervention he demanded was a medical intervention! He did not discuss ANY of the possible negative side effects, did not inform me about ANY implications of pushing this on me against my will! INFORMED CONSENT IS FUNDAMENTAL TO PROTECT YOU FROM MEDICAL VIOLENCE AT THE HANDS OF THESE EDUCATED AND SKILLED PEOPLE WHO HAVE THE TRAINING AND THE KNOWLEDGE TO CAUSE IMMENSE HARM AND PAIN TO YOU IF THEY WANT. In addition the three fillings in my molars they put in JUST three years ago HAVE ALL failed and there is now substantial decay behind these! I came in for my 6-monthly cleaning and examination on schedule just two months earlier, and they mentioned NOTHING about all three fillings failing and there being decay behind them! And yet, now, just two months after my last check up with Dr. Calvin, I am looking at needing TWO ROOT CANALS DONE! HOW did the decay progress so far if I was just seen two months ago at Calvin Dental? Something is telling me, also, that fillings SHOULD last longer than 3 years... AND NOT A PEEP from them at my last check up! Yikes! I am moving to a different practice! Looking for a dentist who will respect my choices, and avoid battering me with unwanted interventions AT THE LEAST!

Starts out as a very nice office seems super Nice and accommodating. However, once we get to…read morebilling things, take a completely different turn. Every single visit I paid hundreds of dollars upfront no problem because it is an estimate of what the patient responsibility is. As soon as I started getting in the EOB's from my insurance company, I could see that I was overpaying by a lot at every visit. Once this was brought up to them they told me that they had a contract dispute with CIGNA.. I tried to have several conversations with them, letting them know that their contract dispute with CIGNA should not be passed along to their patients, and I was thrown out of the office, literally in the middle of my pediatric son having treatment. I have spoken to CIGNA about this supposed disputed contract and CIGNA tells me that they are paying exactly the rates they are required to. So be very careful when you're paying upfront hundreds of dollars and make sure to check with your insurance company and make sure you're closely monitoring those EOB's when they come in. Super nice dentist turned into a complete jerk when she threw me out of the office and my pediatric son. Again, keep in mind that I have no problem paying for my fair share and every time I went into the office I paid the hundreds of dollars upfront with absolutely no questions asked! As she was berating me in the office she also stated that we were customers so that tells you everything you need to know customers equal $$ patients are only patients when they agree to blindly pay whatever they say you should. Balance billing for a dispute you have with your contacted insurance is not a patient problem.

Zero empathy, just focused on making money. And yet they call themselves a "holistic" business. That doesn't sound in alignment. Cold and uncaring. By the way- discrimination against Epilepsy is still Illegal in this country!!!

More money than average, but latest equipment. They are pretty pushy when it comes to looking for money. I actually had to hold back laughing at this particular dentist (gold miner), it was so obvious. Pros: Office is very clean. Staff is very friendly & helpful, hygienists are very good, but the Dentists... VERY pushy. If you bear that in mind (and don't take their pushy methods too seriously), they're okay. I'm considering switching to another dentist because of their constant hunger for $$$.

They drilled a chip in his front tooth and tried filling it. That came out within a week. They did it again and the same issue. I was told not to worry about it, it's fine. His tooth is now breaking down and causing a ton of pain and they refused to help. They even canceled my children's future cleanings. Awful to work with and care solely on the bill they can send you.
