Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.
I am a Board-Certified Adult Psychiatrist specializing in psychiatric medication management, integrative psychotherapy, and intramuscular ketamine therapy with integration support.
I was born in Sarajevo, Bosnia, and at 8 years old, my family immigrated to Germany to escape the war that unfolded in the early 1990s. A few years later, we moved again, settling in California, where I have now lived for 27 years.
Experiencing displacement, cultural shifts, and the challenge of rebuilding life twice over shaped the way I see the world. It deepened my understanding of human resilience, the weight of trauma, and the quiet strength that carries people forward. I have known loss and uncertainty, but also the beauty of adaptation, the power of connection, and the ability to find meaning even in hardship.
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).
It's believed that more than 30-50 percent of individuals with mental health issues do not seek treatment or help. Congratulations, you have already taken a step in the right direction. Just like how a fractured bone causes discomfort and pain, poor mental health also causes day to day discomfort and malfunction. Continuing my analogy, one would expect to take medicine and use a cast to recover from such an injury. I will work with you to understand the situation that you are in and together we will come up with a safe and effective plan. My goal is to get you back up on your feet again without having to feel burdened by your mental health.
Welcome!
I'm a board-certified Psychiatric Mental Health Nurse Practitioner who believes mental health is just as important as physical health. I know that seeking help can feel intimidating, and I want to commend you for taking this first step.
I specialize in working with adults ages 18 to 65 who are dealing with ADHD, anxiety, and depression. My approach is warm, collaborative, and grounded in evidence-based care.
