In it for the money, not helpful at all. Arrogant and did not treat the condition I saw him for. Left the office in tears, minus $385. Refusal to turn over medical records, had to start over with a different doctor.

I was referred over to Dr. Keller for TMJ popping, clicking and severe pain. I had no idea what to expect or if I was seeing the correct person. Dr. Keller was AMAZING! He was able to get my jaw pain under control and down with a manageable level by the time I left. I had almost 90% improvement that continued over the next 24 hours. I have the deepest respect for Dr. Keller and his phenomenal staff. This has been a hard road from jaw pain to eventual surgery. His staff fought to find me a cheaper location to have my MRI, they connected me a reputable and fantastic surgeon and continued to fight for me the whole way. They continued medical therapy to ensure I was comfortable and custom fit an orthotic to minimize further damage due to stress grinding and clinching. Dr. Keller met with me (free of charge) to go over the MRI and advise me on what he thought I should do. He helped explain my option and what each entailed. Did I mention he did all of this at the end of his busy work day after he should have left! I cannot impress upon anyone how fantastic this group is. I felt like the whole world revolved around helping me get better and out of pain, from meeting with me on days off…to staying late. I have never met a more caring group with genuine concern for me…not my money…me! I would recommend Dr. Keller to anyone with TMJ issues (I understand his office does more than just TMJ). I would have met with him years ago had I known what I know now. Ten thousand stars to a compassionate group of people who truly want to help you…from the front desk staff all the way up to Dr. Keller himself. I have never been in better hands and will continue to travel here when I move away, just to continue to have amazing care.

I saw Dr. Keller for TMJ. Not only is he the ONLY in-network doctor for Appliance Therapy in Northern Colorado for my insurance, he is the only DDS medically credentialed by the insurance to perform these services. When I called other offices, I would have had to pay THOUSANDS for the months of treatment. With Dr. Keller, I only had about $500 out of pocket costs. BIG DIFFERENCE! I had no intention of posting a review, but I read some of these negative comments, and I wonder, what office did you go into? The staff was amazing. From the moment I called to the end of treatment, I knew what my costs were, how the insurance would play out, and before starting any treatment, the assistants and doctor walked me through the treatment plan and why. I dont have doctors who spend an hour plus with me one on one like this guy does. If you want a doc who will truly spend the time to get you well and can take your medical insurance, this is the guy.

Dr Keller's office did the best they could with my insurance ----Winhealth---out of Wyoming. Dr Keller is one of only a few doctors in the area who treat TMJ, sleep apnea, migraines. Unfortunatley my mouth did not react well the techniques that Doctor Keller tried. Doctor Keller tried more techniques at no extra charge to me. If I would have had a better insurance company instead of Winhealth my treatment may have been better. Doctor Keller and his staff tried the best they could for what thay had to work with. I would use Doctor Keller's ofdfice again if I needed to be treated again.

The staff was informative and worked hard to get my insurance to pay for my TMJ. I only had to pay my deductible and co-pay. It was great having my medical insurance pay for these services.

He is really expensive and arrogant. Starting using crystals like a witchdoctor and told me that I had heart problems (had just been cleared by a top cardiologist) - out for big bucks, likes to use scare tactics - should not be allowed to be a licensed dentist - watch out for this one.....

This dentist has to be the worst dentist in South Florida. Not only are his prices outrageous but he has an arrogance about him which is sickening. My husband and I were appalled at this guys demeanor. When asking him a question, he rudely dismisses the patient as if he could care less about any of your concerns. He is a sadist as well. His procedures are very painful and he seems to derive pleasure from inflicting pain. His staff is rude as well and very incompetent. His prices are obscene.
