Anxiety and depression therapists and psychiatrists in Sunnyvale, CA

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 anxious, troubled, stuck, weighed down? I believe that you have the inner strength and power to live your best life. But it is hard to be hopeful when you feel trapped by old patterns. That’s where our work together begins. I believe that therapy is a collaborative and creative process. My goal is to help you feel better in the present, while finding deeper insight and lasting change for the future. My style is warm, supportive, interactive, and sometimes humorous. I will adapt our work to meet your unique needs and goals. I believe that the relationship we build in therapy is the foundation for healing and change.

I'm Christina Stelly, DNP, APRN, PMHNP-BC — a board-certified Psychiatric Mental Health Nurse Practitioner based in Martinez, CA. With over 15 years of clinical experience across inpatient psychiatry, maternal health, and advanced practice, I am deeply committed to delivering compassionate, evidence-based mental health care to every person I serve.

I specialize in treating schizophrenia, bipolar disorder, PTSD, depression, anxiety, and etc.

My academic background includes a Post-Certificate DNP in Psychiatric Mental Health from the University of Illinois Chicago, a Doctorate of Nurse Practice from Texas Tech University, and a Master of Science in Nursing from Touro University. I also completed an intensive NP residency focused on advanced psychiatric care, crisis stabilization, and forensic psychiatry, which further strengthened my clinical expertise.

Earlier in my career, I specialized in maternal mental health, serving as a Patient Care Director for high-risk obstetric populations and contributing to perinatal mental health policy at the state and national levels. This background gives me a uniquely broad, whole-person perspective on psychiatric care across the lifespan.

My approach is grounded in trauma-informed, individualized care. I take time to fully understand your history, concerns, and goals before collaboratively building a treatment plan tailored to you. I have also served on health policy committees and presented at national nursing conferences, reflecting my commitment to psychiatric care.

I’m a Licensed Marriage and Family Therapist (LMFT) and have worked in mental health since 2019 across both youth and adult settings, supporting individuals with trauma, anxiety, and depression. I’m passionate about creating a space where you can better understand yourself and feel empowered to make meaningful changes. Together, we’ll explore the connection between your thoughts, emotions, and behaviors so you can walk away with more clarity and options. I believe awareness leads to choice, and choice leads to power.

I have worked with clients in English/Spanish helping adults with co-occurring disorders, at-risk youth, children, adolescents and veterans, with exposure to trauma, neglect, abuse, and parents with parenting issues. Working with these clients early on in my career motivated me to help those who cannot help themselves. Working as a therapist is a rewarding experience as well as a privilege to be invited into another person's life. I find that in joining clients on their journey to make changes and overcome the difficulties in their lives it enables them to discover their best self.

As a therapist providing individual, couples, family, and group therapy, I utilize several frameworks derived from a number of models such as Cognitive Behavioral, Psychodynamic, Solution-Focused, and Narrative.

I have certifications in Trauma Focused Cognitive Behavioral Therapy, CBT, Crisis Oriented Recovery Systems Model, and Managing and Adapting Practices. Also trained in Gottman Couples and EMDR.

I am a Licensed Clinical Social Worker and work statewide via Telehealth. I work with adults, young adults, adolescents, children, and couples. I have experience in dealing with depression, anxiety, trauma, crisis support, grief and loss, and complicated grief.

Are you ready to tackle obstacles and improve your quality of life? Are you struggling with stress, anxiety, depression or ADHD? Do you find it difficult to function in school, at work or to complete tasks at home? Do you feel like other people don’t quite understand you? As I have experienced these struggles myself, know that you are not alone.

As a board-certified psychiatrist who specializes in providing medication management and psychotherapy to all ages, I believe that prioritizing mental health is the key to unlocking happiness and stability in life.
