The review is only for the doctor, everybody else is great, the doctor comes in when he wants or when he feels like it when you're trying to do something he leaves early he don't stay there very long he's not on a set schedule so when you're trying to dose down or you're trying to dose up you're lucky when you catch him or you got to sit there and wait for him to get settled, I've been trying to catch him for a week and finally when I do I'm told to sit and wait because he's not settled in yet he was actually on the toilet, I'm tired of chasing I'm about ready to stop dosing start taking my Lyrica at this point of titrating and not go back!

If they took my insurance which covers everything, it would def be a better experience. However the choice between using and taking my medicine is clear to me and worth the money in the end. However it is a program that you have to work for yourself. No one can do it for you.

Let me just say I was a patient at Medmark for years and above everything no matter what because they open at 4:45 AM says it all. They generally want to meet everyday people’s needs to live a normal life.In and out the door before 5am to do what you need to do w your life. Try and find another clinic that does that for you. You won’t. Working men and women this your clinic. Just no weed. Sorry.
Before you go: availability, cost, and accepted insurance change often. Call the facility to confirm. If something on this page is wrong, tell us and we will correct it.
