As an aspiring college volleyball player, I need my shoulder and lower back to be pain free. Whenever, I come back from a weekend tournament, I am hurting. After seeing Dr. Zeff, I am as good as new. I don’t know how she does it.”
– Courtney K., 16 yrs old. Boulder, Co.


At the age of 51, after having run more than 75,000 miles in my lifetime, both as a collegiate and post-collegiate runner, my body tends to break down after a few weeks of running. Since seeing Dr. Zeff, I feel great. After seeing her for 30 minutes, it feels like she has turned back the clock on my legs about 20 years. I have seen many Doctors, looking for the answer. Jan is the answer. We call her Miracle Jan” – Marty
