Hi, I'm Tandrea Thysell, a California-based Marriage & Family Therapist. I've been providing therapy for most of my life (I think I was born to do this!), but professionally for more than 10 years.
As a Licensed Clinical Social Worker, I believe healing happens through connection, compassion, and understanding. I partner with clients to explore patterns, build coping skills, and develop greater self-awareness in a supportive and nonjudgmental environment. My goal is to help clients feel more grounded, confident, and aligned with their values.
I am a Licensed Clinical Social Worker (LCSW) with over 25 years of experience providing compassionate, trauma-informed care across diverse clinical settings. Licensed in both California and Oregon, my career has been dedicated to supporting individuals and families navigating complex life challenges, including trauma, anxiety, depression, and substance use. I am also Native American and can often relate to clients coming from that community.
My background is uniquely broad, ranging from medical social work and home health to forensic mental health within state hospitals and correctional facilities. I have extensive experience working with Tribal communities in rural Alaska, California, and Oregon, providing culturally sensitive psychotherapy and advocacy. Prior to 2000, my foundational work spanned forensic inpatient care, day treatment, and residential programs.
In my practice, I utilize a collaborative, biopsychosocial approach to help clients adapt to changing health statuses and life transitions. My goal is to provide a safe, supportive environment where patients feel empowered to access resources and achieve meaningful change. I am committed to delivering evidence-based interventions that honor each individual's unique history and readiness for growth.
I am strongly committed to supporting my clients on their journey toward healing and personal growth. My therapeutic approach is rooted in empathy, compassion, and a deep respect for each person's individual process.
I’m Kali, and I have been licensed as a Marriage and Family Therapist in California since 2007. I want to help you have the relationships you want with yourself and with others. I have an MA in Applied Behavioral Science, with a concentration in Systems Counseling. What this means for you, practically speaking, is that as I work with you, I am also thinking about all of the other people, family and friends, co-workers and acquaintances, who are a part of and influential in your life, and you in theirs. I’m also thinking about the relationship you have with yourself, and how all of the parts of you, past, present and future interplay with each other and the world around you. Which is a long-winded way of saying I want to help you have the relationship you want with yourself and with others. I want you to find happiness, joy and health. I'd like to help you identify and meet your goals, and I am a warm, supportive presence whether or not you have any idea as to what your goals might be.
I have been practicing for 40 + years, in the Southbay, Torrance area. I am a psychologist with a Ph.D. I specialize with young children, adolescence. I also work with couples, families and am practized in depression, anxiety, psychosis, and divorce. I utalize cognitive/behavioral and psychdynamic therapies. I match my approach to the personality and needs of thebpatient.
