Dr Goldstein at Canna-Centers is dedicated to providing you with high quality professional care. As a cannabis medicine specialist, she is able to help you decide if medical cannabis is a treatment option for your chronic condition. As a licensed M.D. for 22 years with a clean Medical Board record, she specializes in helping those who have little to no experience with this medicine and will spend the extra time to explain the different methods of use, the different strains and what you can expect. She is considered to be one of the most knowledgeable specialists in the medical cannabis field. Learn more about medical cannabis and the science of the endocannabinoid system at our web site: www.Canna-Centers.com Please beware of other clinics claiming to be legitimate - many doctors with Medical Board problems cannot practice regular medicine anymore so they open a medical marijuana clinic just to make money - this is NOT who you want backing up your recommendation! BEFORE you see a doctor for your letter, get the name of the doctor who is going to see you and then go to http://www.mbc.ca.gov/lookup.html and check the doctor's past history. This is a free service from the Medical Board of California. Also make sure that the clinic is owned by a physician with a clean record and also that they have a fictitious name permit with the medical board- if not, the office is considered to be illegal. It is terribly unfortunate that doctors with terrible judgment, and who have been in trouble in the past, think that it is okay to issue a medical cannabis letter when they could NEVER defend you in court. Canna-Centers guarantees a professional experience. We have been in practice since 2008 because we do it right!
