Attempted to set up an appointment with this office today. Was told that even with insurance and upfront payment of co-pays I would be required to pay a 150.00 deposit prior to scheduling my appointment - monies that would be refunded 4-6 weeks after my initial appointment. When I stated that this seems to completely contradict the purpose of insurance - I was told "Well you don't have to come to our office" completely unprofessional.

Dr Guillory is a fantastic doctor! I tried many others for my stomach problems and chronic hives before finding him. It was such a relief to find someone that understood what I was going through and had answers for why it was happening and solutions to get better. I feel better now than I have in years!
Thank you Heather! So glad we were able to help you!

Hands down the best doctor I have ever had the pleasure of seeing. This guy gets it. He listens and truly cares about you. I have suffered with health problems for most of my life and in one appointment he was able to figure out what was going on and get a plan to get me on the right path. He has changed my life. No one understands thyroid and IBS issues like this doctor. Also, the staff is amazing and the office is inviting.
Thanks Katherine!

I have been going to this office for over two years and I am not at all better off from it. He ignored my concerns and wouldn't even give me the courtesy of running a single test. Come to find out (through a specialist not affiliated with Guillory), I had hyperparathyroidism. I had a parathyroid tumor making 100 times too much hormone, and my body was getting worse by the day. Guillory did nothing to help me, regardless of my literal cries for help. I do NOT recommend him to ANYONE.

Dr. Guillory is extremely passionate about the health and well-being of his patients. He is very knowledgeable and explains everything in detail. The staff at The Care Group is also outstanding. I highly recommend this office, especially for an alternative approach to medicine.
