Addiction therapists & psychiatrists in Upland, 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 bring 14 + years of experience providing thrrapy in both private and clinical settings. My work is grounded in a client centered strengths-based approach, rooted in unconditional, positive regard and a commitment to providing a safe, non-judgmental space where client can openly share their stories.

I identify as neurodivergent and have personally and professionally navigated ADHD. This experience allows me to bring both clinical knowledge lived understanding to my work, helping clients recognize their strengths, develop effective strategies, and move toward meaningful growth and stability.

My goal is to create a space where you feel seen, understood, and supported. I believe mental wellness is an essential part of overall health, and that healing begins by moving from survival to thriving through nervous system regulation, processing past experiences, and strengthening the mind-body connection. Meaningful change and healing happens within a strong therapeutic relationship built on trust, authenticity, and collaboration. Whether you're navigating anxiety, depression, trauma, relationship challenges, addiction, performance anxiety, work-related stress... or simply feeling overwhelmed by life's demands, we'll work together to build insight, process difficult experiences when appropriate, develop practical coping skills, and create meaningful, lasting change.

Hi,

I’m Megan , an LMFT , licensed in California. I am an easy going , kind and compassionate psychotherapist who provides a safe and non-judgmental space for clients to process life’s challenges and grow in self awareness . I empower clients to find their peace and restore balance.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.

I am dedicated to helping teens struggling with trauma and self-harm behavior. My experience working with Orange Unified School District, running groups from grade 6-12 for students struggling with emotional and behavioral problems has given me unique insight into not only helping teens, but also working with the families, schools, and community to provide more effective treatment. I have partnered with Western Youth Services in helping at risk teens and low income families in helping adolescents to overcome academic barriers and families cope with serious defiance and drug use.

Welcome and thank you for taking the time to learn more about me. As a licensed therapist practicing in both California and New York, I believe deeply in the inherent resilience and transformative potential within every individual. I earned my Master’s Degree in Mental Health Counseling from Teachers College, Columbia University. Throughout my clinical practice, I have supported clients across all life stages in navigating complex emotional challenges, including trauma, anxiety, and depression, while empowering them to cultivate healthy, fulfilling interpersonal relationships.

You have probably been carrying something for a while without saying it out loud: anxiety that will not switch off, grief that still ambushes you, drinking that stopped feeling like a choice, or trauma your body has not put down. Helping people find their way through that feels like my sacred calling. Ever since I was young, I've been the person who deeply listens, and I've always sensed the healing that happens when we finally have a trusted, compassionate witness to our story. The story you carry about your past can be the source of your suffering or the key to your freedom, and together we can gently begin to shift it. Whatever pain you're holding, you don't have to hold it alone. I work with individuals, and with couples and families who want to find their way back to each other.
