    When you enter the Riordan Clinic campus from Hillside Street you will wind up a long driveway. At the end of the driveway you'll see a set of white Domes.

There is a sign on Dome 1 that says “Enter Here.” The staff at the front desk will check you in and advise you where to go or will call another staff over to escort you to your appointment or service. Dome 1 is also where you will find our Nutrient Store which is open to the public during clinic hours.
