Clinic Hours
Hours are generally 8:00 am to 5:00 pm and we are closed for lunch from 12:00 pm to 1:00 pm daily. Each clinic has varying days of operation and allergy shot hours, so please speak to the specific clinic staff for exact hours at that location.
In the event of inclement weather, please check our blog for clinic closures and updates.
