Meet Our Team

Our team was assembled by Harvard trained TMS Specialist Dr.Claudia Eppele, MD. Supported through an affiliation of like-minded professionals, TMS Health and Wellness has rapidly grown to become a premier center for TMS Therapy in Southern California. With a success rate of over 90% in terms of reduction of symptoms, we offer the highest quality of service for the treatment of Major Depressive Disorder at our Costa Mesa location.

Here at TMS Health and Wellness we treat the “whole person” recognizing that we are more than just the condition that ails us. Our unique approach to wellness enhances standard care by augmenting TMS therapy with various inner resource tools and natural remedies, such as meditation, mindful self-compassion, homeopathy and aromatherapy. This supports our treatment goal of offering non-drug alternative treatments that actually work.

From the moment you are greeted by our team of professionals, and all throughout treatment , you will feel that your health is central to our mission. We invite you, your family members or those who care for you to be a part of the entire experience.
