I've been with Green Medical for 3 years and saw Dr Karen for all my visits. She is great and knowledgeable. Dr Karen take time to listen and address all my area of concerns unrelated to medical marijuana as well. Don't expect this to be a short visit (I.e. No in and out in like 5-10 minutes like some authorization mill). Medical record need to be make available with qualify condition or you will be denied with absolutely no exception. Due to her solo practice in a small examination room, Dr Karen will only see you by appointment. She won't allow anyone waiting in her room due to patient privacy. I saw her turn away patients that knock on her door without an appointment. Dr Karen also do primary care which I love as well. She is now my go to doctor for all my medical need.
