Our Staff

Our physicians are board certified. A referral from your primary care provider is required to schedule consultation appointment.

Office Telephones

Because of call volume, at times it may be necessary to place your call on hold. Please indicate when asked if you are unable to hold.

We are happy to take your calls during the day. The staff will review your request and will usually return your call by the day end. If you are expecting a call back directly from your provider, please ask staff when you can expect a return call as providers may not be available at the time of your call.

Prescription Renewals

Please do not let your medications run out. We require 48-72 hours advance notice for all prescriptions refills.  Please have prescription name, strength, and dosing information available when you call. You can also request a prescription renewal online.

Providers may require the prescription to be picked up at the office or mailed. We cannot call in any devices with needles/sharps.

Missed Appointments

Your appointment is important. If you can't keep your scheduled appointment, please call our office within 48 hours to reschedule so the appointment time can be offered to another patient. Consistent missed or cancelled appointments will result in our office deferring care to your primary care provider.
