I can honestly say Dr. Park is the best doctor specializing in cannabis here in NY. He makes sure to answer all the... questions you may have and prepares you for going into a dispensary (most doctors don't). I had all my paperwork ready for my first visit and the staff knew Dr. Park was my doctor because of it!read more

I got really lucky to end up with Dr Oliver Park! Not only is the price more affordable then other places; one cannot... put a price on my experience with Dr Park. So kind, patient, knowledgeable and thorough, SUCH A DELITE. Love the atmosphere, attention to detail; Dr. Park answered all my questions and from beginning to end was flawless, easy and fast. I did not feel rushed, in fact the opposite. Knowing I could call him with any question or concern, is priceless! I would not go anywhere else! Thank you Dr. Park for being so AMAZING!read more

I highly recommend Dr. Park as a medical marijuana doctor. He is easy to talk to, knowledgeable about the different... options, and made good recommendations regarding the various dispensaries. He is thorough and stresses throughout the visit that he is available at any time after the visit should any questions or concerns arise. I had some difficulty finding my temporary card on the NYS website, called him, and he returned my call within a minute and showed me exactly where to find it. I chose him even though he was more expensive than some of the other options as I preferred the personal approach rather than going through consolidators. He was able to certify me that same day, after answering my questions, in advance regarding my eligibility (most of the others would not and a couple were actually incorrect in their understanding of what conditions are eligible). I did all of this yesterday and this morning, I have an appointment at a dispensary. Thanks, Dr. Park!read more
