Hello! I’m Dr. Andrew Lampley, a board-certified psychiatrist located in Southern California. I completed my medical training at UC Irvine (medical school), Kaiser Permanente (psychiatry residency), and Duke University (subspecialty). I am one of few psychiatrists in California experienced in providing ketamine treatment for mental health conditions (if indicated).
Are you doing the same thing over and over again and expecting different results? Have you tried countless times to change a your behavior? Have you recently left inpatient rehabilitation or a psychiatric ward and need additional support? Do you feel like your mood, anxiety, and depression are running your life? Making these changes can be extremely difficult and cannot be done alone. My name is Lauren Debski. I am a dual board-certified family and psychiatric-mental health nurse practitioner.
I am a double board-certified family and psychiatric/mental health nurse practitioner. As a Family and Psychiatric Nurse Practitioner, I believe that healing begins with understanding. My goal is to create a safe, supportive space where you can share your story without judgment and work toward meaningful, lasting change. I provide individualized, evidence-based care for adults facing depression, anxiety, PTSD, bipolar disorders, ADHD/ADD, and sleep disorders.
Welcome! I’m Sarah Stewart, and I specialize in medication management for adults dealing with depression, anxiety, ADHD, bipolar disorder, and other mental health conditions. Together, we’ll explore your goals, strengths, and patterns to create a treatment plan that feels personal and empowering. My approach blends evidence-based care with compassion and collaboration—helping you find both immediate relief and lasting stability. You deserve care that meets you where you are and helps you move toward a more grounded, confident version of yourself.
I provide a safe, supportive, and nonjudgmental space where we work together to understand your unique needs and goals.
I believe healing happens when patients feel seen, heard, and empowered. My role is to walk alongside you, offering tools, education, and medication management tailored to your individual journey.
I completed my training as a PMHNP in California and have experience in both emergency and outpatient mental health settings.
If you’re ready to take the next step in your mental health journey, I look forward to working together to build a plan that supports your well-being.
As a Psychiatric Mental Health Nurse Practitioner (PMHNP), I have been granted the invaluable opportunity to assist those seeking understanding and relief from their anxiety, depression, psychosis, and fragile self-regard. With over 20 years of clinical experience, I’ve developed a deep, sincere compassion for each client’s unique journey. My approach centers on empowering individuals toward recovery, self-agency, and holistic well-being.
