Book a therapist or psychiatrist in Temecula, CA covered by Cigna

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 am a licensed clinical psychologist with more than 35 years of experience working with adults and adolescents. I use trauma-informed approaches to help clients heal from trauma, improve performance, and expand health and creativity.

I specialize in working with personal growth and development; grief and loss; trauma and childhood family dysfunction; dissociative phenomena and parts; death and dying; self-criticism and negative core self-beliefs; depression and anxiety; identity and meaning.

When a teen is struggling, the whole family can feel it. I work with teens and parents facing emotional overwhelm, behavior challenges, family conflict, and stress. Therapy with me is supportive, engaging, and focused on practical tools you can use in daily life. My goal is to help families feel more connected, understood, and hopeful.

My goal is to create a space where you feel genuinely heard, understood, and supported. I believe healing begins through connection, and I strive to build a therapeutic relationship that helps you better understand yourself, navigate life's challenges, and create lasting change.

My experience spans crisis intervention, individual counseling, and a variety of therapeutic settings, giving me a broad foundation to draw from. Rather than taking a one-size-fits-all approach, I meet each client where they are and tailor therapy to their unique needs, goals, and strengths.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) dedicated to providing compassionate, patient-centered mental health care to individuals across California. With a background in both nursing and psychiatry, I specialize in diagnosing, treating, and supporting patients with a wide range of mental health conditions, including anxiety, depression, ADHD, bipolar disorder, and more.

Are you or your child struggling with anxiety, depression, trauma, or a life change and wishing to feel heard? I support children, adolescents, adults, and families, with a focus on anxiety, depression, trauma, life transitions, and relationship challenges. In English and Spanish, I help clients work through emotional overwhelm, family stress, ADHD, addiction, anger, and difficult experiences.

Whether you are seeking support for yourself, your child, or your family, I will listen without judgment and work alongside you. Together, we can understand what feels difficult, build on your strengths, and move toward meaningful change.

I provide compassionate, evidence-based mental health care in a safe, judgment-free space.

I specialized in working with preteen, teens, young adults and adult individuals. My purpose is to provide an empathic, supportive space in which you can speak freely about your experiences, consider issues of identity, and explore relational possibilities. I understand that family dynamics can be complex and challenging. Through therapy one can uncover the past and find a deeper connection on how thoughts impact the behavior in the present.

I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) dedicated to providing compassionate, evidence-based mental health care in a supportive and judgment-free environment. I work with adolescents and adults experiencing a variety of concerns, including anxiety, depression, trauma, mood disorders, ADHD, OCD, and other psychiatric conditions.

I believe that every individual deserves to feel heard, respected, and understood. My goal is to partner with each client to develop a personalized treatment plan that aligns with their unique needs, values, and goals. Whether you’re seeking medication management, diagnostic clarification, or support through a difficult season of life, I strive to provide care that is collaborative, thoughtful, and centered around your overall well-being.

I recognize that reaching out for mental health support can be difficult, and I consider it a privilege to walk alongside my clients in their journey toward healing, resilience, and lasting wellness.
