Peterson Pierre, Chair

Peterson joined the board in 2019 as a Registered Nurse with over 30 years in the acute care setting. He is currently reading for a Doctor of Nursing Practice Degree at Pennsylvania State University. Peterson also holds a Master of Science in Nursing from Sonoma State University.  He also practices as an emergency nurse at a local hospital in Sonoma County.  He noticed mental health patients are not treated with the same urgency as medical patients during his career, and transfer to inpatient behavioral facilities is much delayed. He is hoping to see improvement in that area. Peterson is a part-time clinical faculty at UCSF School of Nursing.

Gregory Fearon

Gregory joined the Board after years of service in developing and operating homeless facility and service agencies.  Experiencing inadequate collaboration and partnerships between community agencies he led and County mental health and recovery services, he decided to pursue appointment to the Mental Health Board.  Observing inconsistent and  under-developed support for public engagement with all of the boards and commissions, he is looking forward to strengthening the abilities of all involved.  

He also has a long history of nonprofit board membership in support of the California coast, and of our redwood forests and parks.  Growing up surfing in Southern California, and learning to love our earliest civilizations, his travels have taken him to the world’s most exciting ruins and surf spots.
