Make an Appointment

Call 727-767-7438 to schedule an appointment. 

However, if you or your primary doctor feels that your child needs to see a rheumatologist before the next available appointment, your doctor will need to discuss this with the pediatric rheumatologist.

Records from your primary or referring doctor must be sent in advance in order to schedule an appointment. This includes: demographic and insurance information, office notes, lab results, radiology reports, and a referral. It is very important that the specialists have all the information they need so your child receives the best care possible. Once this information is received, the scheduler will call you to make the appointment. Our fax number is 727-767-8270.
