If you're a woman feeling stretched thin by the relationships in your life — a partner, your family, the demands of parenting — you don't have to sort through it alone.

I hold a Master of Science in Clinical Social Work from Azusa Pacific University, and my goal in every session is simple: you leave feeling heard, understood, and a little more capable than when you arrived.

I offer a therapeutic approach that is collaborative, warm, and practical. My goal is to create a space where you feel comfortable, supported, and empowered to explore your experiences and move toward meaningful change.

Hi, I'm Jennifer Eastman, a Board-Certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner passionate about helping people through comprehensive medication management tailored to your unique needs. I'm currently pursuing my Doctorate in Nursing at Western University of Health Sciences, where I also completed my Master of Science in Nursing and post-graduate certifications in both Psychiatric Mental Health and Family Practice. This dual training gives me a holistic perspective on how mental health intersects with overall physical wellbeing. I bring over 20 years of healthcare experience to my practice, including years as a Registered Nurse in pediatrics and emergency care, where I became a Certified Emergency Nurse. My extensive work in clinical research as a Sub-Investigator in CNS clinical trials has kept me current on the latest evidence-based treatments and emerging medication options. I specialize in psychiatric medication management for adults and adolescents, treating ADHD, depression and mood disorders (including bipolar disorder), anxiety disorders, and personality disorders. I take time to understand your complete story—not just your symptoms—so we can develop a treatment plan that actually works for your life. My approach integrates both pharmacologic and non-pharmacologic interventions, and I carefully monitor treatment response to make adjustments as clinically indicated. I believe in trauma-informed, culturally competent care, creating a safe space where you feel heard and respected. I understand that starting or adjusting psychiatric medications can feel overwhelming, which is why I prioritize clear communication, patient education, and shared decision-making throughout your treatment. I don't just prescribe medication—I partner with you and collaborate with therapists, primary care providers, and other supports in your life to ensure comprehensive care for long-term stability and improved quality of life.
