How to Schedule an Appointment

All new patients will be required to complete new-patient paperwork, which will be provided by mail or email. We must receive a complete set of medical records at least two weeks before the first scheduled appointment to give the doctor sufficient time to review all medical history. This will help you get the most comprehensive care at your first appointment.

To schedule an appointment, please call 727-767-8181 with a referral from your former provider or current provider who is concerned about mitochondrial disease.
