Shawn V Giammattei, PhDShawn V Giammattei, PhD

I am a Clinical Psychologist specializing in individual, couples and family therapy. I maintain a private practice in both San Francisco, CA and Santa Rosa, CA. As a narratively informed,  culturally sensitive, psychologist, I work  collaboratively with clients to find solutions to the problems that are negatively impacting their lives and relationships. My approach to therapy is interactive and solution-focused. I integrate complementary methodologies and techniques to offer a highly personalized experience that is tailored to each client or family's needs. 

With compassion and understanding, I work with individuals, couples, and families to help them  build on their strengths and attain the personal growth and interpersonal relationships they are committed to achieving.

I primarily work with couples and families dealing with a wide range of problems including family conflict, parenting, couple relationship issues, sexual and gender identity issues, anxiety, trauma, eating disorders, addictions,  obsessive-compulsive disorder, and child/adolescent behavioral problems.

I am an active member of the World Professional Association for Transgender Health and specialize in the treatment of gender identity issues in children, adolescents and adults, as well as  lesbian, gay, bisexual and transgender couple and family issues.



Dr Lisa Richards

Dr. Lisa Richards

Dr. Lisa Richards received her doctorate in clinical psychology, forensic track, from California School of Professional Psychology at Alliant International University. Richards is a member of the LGBTQ+ community and is also a certified LGBT-informed therapist by The Rockway Clinic in San Francisco. 

She completed a predoctoral internship at Mississippi State Hospital where she provided individual, group, and crisis interventions to individuals with varying degrees of mental illness and chemical dependency. There she utilized a LGBTQ+ affirming approach and created a group for LGBTQ+ clients in the chemical dependency program. 

Richards’ postdoctoral fellowship was completed at Mule Creek State Prison which is a transgender hub within CDCR, meaning that many transgender individuals reside at that institution and the appropriate services are available for them. While at Mule Creek, she provided gender health evaluations for individuals requesting gender affirming surgery as well as individual and group therapy. 

She has since transferred to California Department of Corrections - Sacramento which is also a transgender hub. Dr. Richards’ therapeutic approach is trauma-informed and integrative, including evidence-based practices (CBT, DBT, ACT). She is motivated to engage with clients in a non-judgmental manner and to create a sense of value. 

“My aim is to assist clients in exploring and aligning with their authentic self. I look forward to hearing from you and joining you on this journey into self-exploration.”
