Learn about the different approaches, education and specialties of each of our team members.



Phil Boissiere, MFT is a couples and adult ADHD specialist based in San Francisco & the Silicon Valley. He brings his zest for life, professionalism, and humor to all aspects of his work. He dedicates himself to helping people overcome life’s hurdles with purpose and passion. He believes that when motivated people are given the tools to succeed they will reach their goals and live a life that is rich with meaning.

However, when those same people find themselves bogged down in a directionless therapeutic process, they can become “lost in therapy” and actually suffer because of it. His goal-focused approach and use of evidence based practices, such as Cognitive Behavioral Therapy (CBT), skills training, and Attachment Focused Therapy form an empowering therapeutic process. He also brings education and understanding neurology and it’s role in mental health and happiness to his clients. He believes that having an in depth understanding of both our inner thought processes as well as our internal physical make up, is important to long lasting psychological and social change.

Phil is also married to Erika Boissiere, the founder of The Relationship Institute of San Francisco. Should you ever feel that you were referred to Phil and it is not the appropriate therapeutic fit, he welcomes the opportunity, as do all the clinicians associated with TRISF,  to give you additional referrals to other therapists.
