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'm an open minded individual and welcome any topics in treatment
Hi, and welcome! I am Joy Nnebe, a Psychiatric Mental Health Nurse Practitioner. I am thrilled you’re considering working with me.
I have 8 years of experience in psychiatric/mental health nursing, and I specialize in treating anxiety, depression, bipolar disorder, ADHD, trauma, and more, using approaches like CBT therapy and trauma-informed care. I aim to provide simple, non-judgemental, supportive, and personalized care to help you feel understood and empowered on your mental health journey.
Are you struggling to have harmony in your relationships? Does having ease in your life seem like a far-fetched dream? Are you feeling overwhelmed with the state of the world and all you have to do? Welcome, you're in the right place! I have been in your shoes and the first (or twenty) step is always the hardest. As someone who has learned to balance multiple cultures, I know what it can feel like to straddle various parts of your identity. I have first hand experienced feeling overwhelmed, frustrated, angry, and at a complete loss for how to navigate the intensity of my emotions. This has informed my practice and work with clients where I strongly believe that our emotions guide us to understanding ourselves in a new light. Asking for help can be difficult, especially in a culture that values productivity over personality.
I believe that every person is born with the capacity to live a full, meaningful, and joyful life. Through life's challenges, losses, relationships, and unexpected experiences, we can become disconnected from that sense of wholeness. My role is to provide a compassionate, supportive space where you can reconnect with yourself, better understand your experiences, and move toward healing. I view therapy as a collaborative process built on trust, respect, and genuine human connection.
I enjoy helping clients find their innate wisdom and to grow in positive ways through therapy. My background is in traditional and integrative psychology, energy healing and spiritual development. I am committed to helping clients find tools to address issues of chronic inner and outer pain, to find balance and meaning, and to improve their quality of life and relationships. I feel grateful and humbled to be part of my clients' process of discovery and change.
It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.
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 graduated from UCLA's Social Welfare program and developed a specialty working with adolescents, teens, parents, teachers and school administrators via the LAUSD public school system. Over the course of 15 years, I have developed an expertise in utilizing a trauma-informed lens and attachment theory to address treatment areas such as trauma, depression, parenting, parent-child relationships, behavioral issues and anxiety.
I believe that in order for therapy to be effective, the client has to participate in the process. I am not a magician. I don't have a magic wand. Changing old behaviors and patterns can be difficult and painful but i am willing to be there to support you on your journey to better health.
I am a Licensed Clinical Social Worker (LCSW) with 28 years of experience in the mental health field. I earned my Master of Social Work (MSW) from the Hunter School of Social Work and have lived and practiced in California for over three decades. My professional background includes extensive work with older adults, individuals experiencing homelessness, and adults living with severe and persistent mental illness. I am known for my patient, compassionate, and attentive approach, and I strive to be fully engaged and present with every client I serve. My goal is to provide thoughtful, individualized support that helps clients feel understood and empowered in their therapeutic journey.
