I am a clinical psychologist licensed in California and Illinois, and can see clients from both states. I have worked with clients in the areas of depression, anxiety, relationships issues, addictions, stress management, sport and performance, bipolar disorder, and binge eating disorder. My therapy style is personable, connected, focused, and attuned.
I believe that the client, not the therapist, is the expert in their own life. My goal is to support and guide my clients see their strengths, increase self-awareness, and develop new skills to help them live a more satisfying life and build healthier relationships.
I have a Ph.D. in Clinical Psychology with over 20 years of experience in the mental health field working with youth and adults in clinical, research, and forensic settings. I have experience in treating a wide range of mental health problems and severity. I specialize in working with depression, anxiety, trauma, anger, relationship problems, and family conflict.
I have extensive experience in working with individuals new to therapy and who belong to cultures that tend to stigmatize mental health treatment.
I am a highly skilled therapist with a strong focus on trauma therapy, substance abuse, and mental health. I hold dual licensure as a Licensed Marriage and Family Therapist, and as an Associate Clinical Counselor. My educational background includes a Master of Arts in Counseling Psychology from William Jessup University and a Bachelor's degree in Psychology with a minor in Child Development from California State University, Chico.
Welcome! I am Dr. Lyssabeth Mattoon, PhD, a clinical psychologist and trauma specialist, skilled at providing individual and family therapy for adolescents, children and adults. My calling in life is to support and empower trauma survivors to harness their inner strength as part of the healing process.
