Trauma and PTSD therapists & psychiatrists in Orange, CA

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.

I entered into this field to help individuals to learn, grow and heal at their own pace. I fundamentally believe that we are the experts of ourselves and our experiences. My role through my education, learning and experience is to support clients’ in unlocking their awareness of patterns to increase the clients’ ability to access the tools within them to facilitate their learning, growth and healing through a collaborative process.

As a Black/African American woman, I am passionate about working with people of color (especially people of color who identify as LGBTIA+) in destigmatizing mental health in our communities and identifying how systemic racism/systemic oppression affect our mental health.

My strengths as a therapist are rooted in fifteen years of experience working in the field as a mental health clinician in a variety of settings. I have supported individual’s ability to access their inherent tools to overcome struggles connected to trauma, grief & loss, depression and general anxiety. Over the course of my experience I have developed skills in providing therapy to underrepresented, underserviced families, children, individuals, and couples. I also have a wealth of experience supporting youth involved in the juvenile justice system, oppositional teens, and members of the LGBTQIA+ community.

If you’re struggling with your relationship with food, your body, or feeling stuck in cycles of restriction, bingeing, or guilt, you are not alone—and you don’t have to face it by yourself. In my private practice, I specialize in working with individuals navigating eating disorders and disordered eating.

I provide compassionate, individualized therapy for adolescents and adults experiencing anorexia, bulimia, binge eating disorder, chronic dieting, and body image concerns. In addition to eating disorder treatment, I work with children, teens, and adults facing anxiety, depression, trauma, personality disorders, substance use, and challenges related to identity and the LGBTQIA+ community. I am committed to creating an affirming, inclusive space where clients of all backgrounds feel seen, respected, & supported.

My passion is helping individuals find healing, balance, and inner strength. With compassion and care, I support clients as they navigate life’s challenges, building resilience, self-awareness, and emotional well-being along the way.‍I provide evidence-based treatment tailored to each person’s needs, drawing on mindfulness, trauma-informed approaches, and personalized care plans. My goal is to create a safe and supportive space where clients can reconnect with themselves and develop the tools for lasting wellness.

I’m a Licensed Marriage and Family Therapist with over nine years of clinical experience helping adults navigate anxiety, trauma, relationship challenges, life transitions, stress, self-esteem, and patterns that can leave them feeling stuck, overwhelmed, or disconnected from themselves and others.

I have practiced therapy in several levels of care; outpatient, intensive outpatient, and partial hospitalization programs. I have been practicing as a therapist since 2017, working with a diverse range of clinical presentations.

Robert Troy Vander Zwart obtained his Master's Degree at Gordon Conwell Theological Seminary and has over 25 years of experience. Prior to beginning in his private practice Troy worked in a variety of clinical settings. Troy's specialty is counseling individuals with symptoms of depression and anxiety and who have experienced trauma. He also has a passion for couples counseling, marriage and pre-marriage counseling, and family therapy.

I am a Licensed Marriage & Family Therapist and I currently work remotely in California. I have a Master's degree in Clinical Psychology from Pepperdine University, and I have been licensed in Marriage & Family Therapy since 2008. I spent the first half of my career in public service, specifically working in the nonprofit sector and on the county level in Los Angeles, Orange and Monterey Counties. I started my private practice in 2012, and since that time I've worked primarily with individual adults experiencing trauma-related symptoms, mood dysregulation (anxiety, depression), and relational challenges (codependence, narcissism, attachment issues, fractured family of origin).
