For clients with insurance other than BCBS: Our services may still be covered in full or in part by your health insurance or employee-benefit plan. Most PPO and POS plans have "out-of-network" benefits that will cover some percentage of the cost. If you have an HMO from a company other than BCBS, most likely your insurance will not cover our services and you would need to pay directly. Read about the benefits of seeing an out-of-network provider here.

Message to clients

"I provide a warm, attentive, and interactive psychotherapy relationship that aims to help people deepen their self-understanding, break out of hurtful patterns, and develop new modes of thinking, feeling, and relating to others that will reduce depression and anxiety. I am particularly interested in trying to help clients feel freer, more real, more connected, and more like the authors of their own lives, so that they can achieve what they hope for in work and relationships."
