I am a double board-certified Psychiatric–Mental Health Nurse Practitioner with over 20 years of experience across the continuum of psychiatric care, including acute psychiatric emergencies, inpatient and outpatient psychiatry, geriatric mental health, intellectual and developmental disability services, and healthcare management. I hold a Master of Science in Nursing (MSN) and am currently completing my Doctorate, reflecting my ongoing commitment to clinical excellence, evidence-based practice, and lifelong learning.
Throughout my career, I have worked with individuals and families navigating a wide range of psychiatric conditions, from situational anxiety and depression to severe and persistent mental illness. My clinical experience includes extensive work with schizophrenia and psychotic disorders, bipolar disorder, major depressive disorder, generalized anxiety disorder, panic disorder, obsessive–compulsive disorder (OCD), trauma-related conditions, and mood instability across the lifespan. I am particularly experienced in caring for geriatric patients, individuals with intellectual and developmental disabilities, and patients with complex medication regimens requiring careful evaluation, simplification, and long-term stabilization.
I also work closely with college-aged patients and adults who are navigating academic pressure, career transitions, family dynamics, identity development, and the cumulative stressors that can emerge during periods of high responsibility or change. Many of my patients are high-functioning individuals who appear “put together” on the outside but struggle internally with anxiety, rumination, intrusive thoughts, emotional dysregulation, or burnout. Others are managing chronic psychiatric illness while striving to maintain independence, relationships, and quality of life.
I provide compassionate, comprehensive mental health care tailored to teens and families navigating complex mental health challenges. As a psychiatric-mental health nurse practitioner (PMHNP), I specialize in treating depression, anxiety, OCD, mood disorders, and ADHD through integrative psychiatry and medication management.

I’m a Doctor of Nursing Practice and board-certified psychiatric nurse practitioner who works with clients across the lifespan. I specialize in treating depression, anxiety, and complex or treatment-resistant conditions. I have advanced experience with innovative treatments, including Spravato and Transcranial Magnetic Stimulation (TMS). My goal is to provide thoughtful, individualized care for those who may not have found relief with traditional approaches alone.
I believe mental health treatment works best as a collaborative partnership. I take time to understand each client's unique experiences, symptoms, strengths, and goals before developing an individualized treatment plan. Treatment may include medication management, psychoeducation, lifestyle recommendations, and referrals for therapy or additional services when appropriate.

Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Yuma starts with understanding what kind of care fits your needs. Psychiatrists and psychiatric nurse practitioners can diagnose mental health conditions and prescribe medication, while therapists provide talk therapy. Medication management can include evaluating symptoms, discussing care options, and tracking how your plan is working over time. If you are looking for support with anxiety, depression, ADHD, bipolar disorder, OCD, or medication management, review each psychiatrist’s listed specialties and training to see how closely they match what you want help with.
In a smaller city like Yuma, local psychiatric options may be more limited than in larger metro areas. Virtual appointments can expand your choices while still letting you search for someone licensed in Arizona. Psychiatric appointments for medication management are often shorter and less frequent than therapy sessions, and some psychiatrists also provide therapy. Some people work with both a therapist and a prescriber. Before booking, read psychiatrist bios for details on clinical focus, appointment format, scheduling flexibility, and whether a free phone consultation is offered.
Psychiatric care in Yuma can be a significant expense without insurance. Using in-network insurance is one of the most reliable ways to lower your out-of-pocket costs. Headway helps you find psychiatrists who match your needs, may accept your plan, and are accepting new patients. You can enter your insurance details to see estimated costs before you book, compare virtual and in-person options, review bios, and book directly when you’re ready.
If you're already taking psychiatric medication and considering switching providers, talk to your current prescriber before changing or stopping any medication — most psychiatric medications shouldn't be stopped abruptly. Anyone experiencing thoughts of self-harm or in acute crisis should call 988 or go to the nearest emergency department rather than wait for an outpatient appointment.
