Great doctor

I’ve had been a patient of Dr Mark’s for about 3 years and he is absolutely the best doctor around. He has a wonderful line of pharmaceutical grade supplements and my health has improved so much since I’ve started seeing him. He’s clearly very dedicated and a very compassionate doctor. Highly recommend him.

Excellent physician

If you are looking for a thorough and knowledgeable doctor, look no further. Not only is he training in conventional medicine, he is also trained in functional medicine, which means he offers you options to stay on drugs forever, or help you find a more natural solution, such as natural supplements. I have been in very poor health for many years, and taking his line of supplements which are pharmaceutical grade, have really helped to heal my gut and overall health. I'm so glad his wife helps develop his line of functional supplements since she is a PharmD and specialized in both the use of drugs and supplements.

Money Driven Office

He is a competent doctor but my concern is he is more into it at this point for the money. Billing is a bit of a mystery to me and charges for something like a 30 minute visit might be close to $200 with insurance deductions if you have a high deductable plan. The costs of this doctor are unreasonably high for a quick check up and you'll likely find yourself owning thousands. Ask about charges up front.

Horrible office

Adriana is the worst person in the office. Just ahead of the doctor, who only wants to sell you his own probiotics. (Which is not covered by insurance) do not go to this office.
