Practitioners

The referral world has gotten quite complicated. The health care providers that we encourage patients to work with all have different availabilities. Some do only office work, some telemedicine and office work and some just telemedicine. We encourage prospective patients to check with each provider separately as to their availability and style of practice. We cannot recommend any specific practitioner because each patient needs to get a sense from the practitioner if this is the right fit.
