Bipolar disorder therapists & psychiatrists in Yuma, AZ

Hello. My name is Mary ‘Sarah’ Houston. I have been a Mental Health nurse for 20 years. I have been a Psychiatric Mental Health Nurse Practitioner (PMHNP) since November, 2016. As a PMHNP, I have worked inpatient and outpatient psychiatry, along with working at a crisis stabilization unit for mental health crises. As well, I have training in mental health Telehealth. I have worked with clients with depression, anxiety, insomnia, schizophrenia, bi-polar disorder, substance use disorder, and PTSD.

I have a passion to help those with emotional and mental health needs.

My goal is to provide a safe environment for my clients to come and talk about their thoughts, behaviors, and emotions, and work towards positive self-acceptance and love.

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 am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with over 10 years of experience in the mental health field. Throughout my career, I have worked in both inpatient hospital and outpatient settings, caring for individuals with a wide range of mental health conditions across the lifespan.

My passion is women's mental health. I specialize in supporting women through the unique emotional and psychological challenges that can occur during different stages of life, including postpartum, premenstrual dysphoric disorder (PMDD), infertility, menopause, anxiety, depression, and trauma. My goal is to help close the gap in women's mental health care by providing compassionate, evidence-based treatment that empowers women to better understand their mental health and take an active role in their well-being.

With over 9 years of experience as a Psychiatric Mental Health Nurse Practitioner, I have had the privilege of supporting individuals from childhood through older adulthood in navigating mental health challenges. I specialize in treating a wide range of conditions, including anxiety disorders, OCD, PTSD, mood disorders (such as Major Depressive Disorder and Bipolar Disorder), psychosis, ADHD, ASD, and substance use disorders, including opioid and alcohol use disorder.

I bring a unique perspective to my practice as a Foreign Educated Physician and Pharmacist, which enhances my ability to provide thoughtful, holistic care. My approach is rooted in the biopsychosocial model, emphasizing patient-centered strategies that consider your mind, body, and environment.

I firmly believe in the possibility of recovery. Many of my clients are inspired to discover that, with adherence to an individualized treatment plan, meaningful progress and improved quality of life are achievable.

My goal is to create a safe, supportive space where you feel understood, empowered, and guided toward the mental wellness you deserve.
