Our medical evaluation is a two step process. 1 On the first visit, we will draw your blood, conduct a medical history intake and answer any general questions you may have about us and our treatments. 2 On the second visit, we will go over your labs and discuss your personalized treatment plan. You may have your encounter with our medical provider on the 1st or 2nd visit.

To receive the 99.00 promo price for your initial evaluation, prepayment prior to your appointment is required. Upon receiving your appointment request, we will call you to help you securely pay over the phone - or give us a call at 5106793300.
