Hello, my name is Kateri Ross, and I am a Licensed Marriage and Family Therapist. I earned my Bachelor of Arts in Psychology from the University of California, Davis, and my Master of Arts in Counseling Psychology with an emphasis in Health Psychology from Santa Clara University.
My clinical background includes work in both community mental health and private practice settings, where I have helped individuals manage acute challenges as well as long-standing emotional and behavioral patterns that impact daily functioning and overall well-being.
I specialize in working with adults ages 18 and older experiencing anxiety, depression, OCD, trauma, postpartum depression and anxiety, binge eating, perfectionism, procrastination, stress management, and life transitions. I also support individuals who struggle with self-critical thinking, guilt, shame, emotional overwhelm, managing stress or difficulty maintaining balance during demanding phases of life.
