I am multiply disabled and have a truly complex medical history.To find any doctor willing to read my medical history has been difficult since I was a child. Dr. Altvater is an outstandingly patient doctor who took the time to get to know me and discus my medical history. I strongly believe my non-cannabis doctors could learn a lot from Dr.Altvater. My visit was quick,easy and actually fun something most of my more traditional doctor's visits are not.He was also willing to wait for records from multiple doctors offices for my visit. In closing, I would highly recommend him.
