About Us

Robin Taylor Kirk, LMFT
Executive and Clinical Director

With an integration of complimentary approaches, including Psychodynamic Psychotherapy and Acceptance and Commitment Therapy (ACT), Ms. Kirk tailors treatment to that which is most helpful for each individual.  Insight into the dynamics that originated and continue to maintain problems is very important, but it is often not enough.  Developing the willingness to experience fully a wide range of emotions is one factor that makes change possible and will allow you to feel at ease in your life.

Ms. Kirk has been in the mental health field for over 20 years and specializes in the treatment of Anxiety Disorders (Obsessive-Compulsive Disorder, Phobias, Social Anxiety) and Eating Disorders (Anorexia, Bulimia, Compulsive Eating, Compulsive Exercise).  Her interest in Eating Disorders began when she was the Student Director of the Weight Control Clinic at San Diego State University.   After becoming a Licensed Marriage and Family Therapist, Robin co-owned Summit Eating Disorders Program (now Eating Recovery Center of California) which offered both Intensive Outpatient and Inpatient Programs in Sacramento.  Many of her clients also suffered from an Anxiety Disorder and she became very interested in the treatment of anxiety, including OCD.    As a result of her interest in ACT and her recognition of the limitations of a singular Exposure and Response Prevention (ERP) model of treating OCD, Ms. Kirk developed Sage's Anxiety Treatment Program which includes and combines ERP techniques with ACT core processes with the result that treatment tends to be much more approachable and integrated more easily than with ERP alone.  In 2014, Ms. Kirk founded the Sacramento Affiliate of the Association for Contextual and Behavioral Sciences (the association for ACT).

Robin is a graduate of the International OCD Foundation Behavioral Training Institute, has received in-depth training in Acceptance and Commitment Therapy (ACT) and has participated in a 7-day intensive mindfulness-based stress reduction meditation teacher training program under the direction of Dr. Jon Kabat-Zinn and Dr. Saki Santorelli.

Robin presents on the subjects of the use of Mindfulness in psychotherapy, Obsessive-Compulsive Disorder and ACT.  She is an instructor in the Continuing Education program for JFK University and the Professional Development Program at the Community Institute for Psychotherapy in Marin, California.  She provides supervision for psychotherapy interns and consultation for licensed clinicians. Ms. Kirk has served on the boards of the Sacramento Eating Disorders and Outreach Program, Sacramento OCD Foundation, and the Sacramento Valley Association for Psychoanalytic Psychotherapy.  She is also happy to present to local groups on topics related to anxiety disorders, Mindfulness and ACT.  California License Number:  MFC 37167.
