A mental health clinic rooted in compassion and purpose.

OUR JOURNEY

Acacia Clinics opened its doors in 2018 after founding members Dr. David Carreon and Dr. Nathan Meng, both Stanford Medicine alumni, were disheartened by the mental health care’s stagnant nature. Even while training at one of the top psychiatry programs in the world, there was a general resignation that some patients may never get better.

Dr. Carreon and Dr. Meng shared a vision that there was a better way to approach mental health care. A way that honored patients as unique individuals, not a collection of chemicals. Together, they founded Acacia Clinics, which integrated research, patient-focused care, and cutting-edge therapies to provide the best experience and results.

Today, the clinic is the leading provider of the latest mental health treatments with the aim of helping patients not merely exist but flourish.

OUR SYMBOL

Acacia trees are strong and resilient. They can survive the harshest conditions — even drought and fire. From its roots, the tree will regrow. And with proper care, its branches will bloom and flourish.

The human experience has great range, much like an acacia’s journey. Life can shift from content to debilitating or challenging to triumphant in moments.

Acacia is a place where people who have suffered from mental illness for years, decades, and even most of their lives, find hope. When treatment has ended, the goal is to do more than survive but flourish — evidenced by a life decorated with plentiful vibrant blooms.
