Our Referral Philosophy
Patients Who Ask for Cornerstone by Name
An increasingly common scenario: a patient you’re referring for oral surgery asks to be sent to a specific provider. At Cornerstone, we believe the best marketing is a patient who has heard from someone they trust that their experience here was different — calmer, more attentive, less rushed. We encourage dental practices to let their patients know that Cornerstone is an option when a referral is needed.
