A friend recommended I contact Dr. Julia Greenspan to rule out Lyme Disease and it was the best decision I could have made. As it turned out, my tick bite from July was responsible for a cascade of neuromuscular events that began in September and nearly had me in surgery by December. Dr Greenspan listened to my story, ordered lab work to confirm her diagnosis and immediately started antibiotics with herbal supplements to support her treatment protocol. It’s February and the residual effects of my Lyme Disease, like fatigue, headaches and brain fog, have completely lifted. I am forever grateful to Dr Greenspan for her medical expertise, skilled care and gentle support. This, from a 74 year young former critical care nurse who was able to maneuver through allopathic medicine to find complete healing from a naturopathic doctor.

I was sort of misunderstood by my primary care provider for over a year… I started seeing Dr. Greenspan last August and 4 months later I feel great for the first time in over 2 years… she listened to my plight , asked great questions about my symptoms, and provided me with medications that apparently are working great. I couldn’t be more impressed with her and her staff.

Greenhouse Naturopathic Medicine is a place to go when nobody else will help you. Dr Julia Greenspan is well versed in treating any illness including all tick borne diseases. It’s such comfort to have a doctor who really cares and who will never gaslight you or make you feel like you are crazy. I always feel heard here.
