Bipolar disorder therapists & psychiatrists in Flagstaff, 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.

I’m a board-certified Psychiatric Mental Health Nurse Practitioner with experience working in both inpatient and outpatient settings across Arizona. I’ve worked closely with individuals experiencing anxiety, depression, trauma, bipolar disorder, and more complex mental health challenges. My background includes crisis work, outpatient care, and medication management, allowing me to meet you in both difficult seasons and times of growth. I’m passionate about providing supportive, evidence-based care that meets you where you are.

I'm Dean, a Licensed Professional Counselor (LPC) in Arizona with years of clinical experience across mental health, substance use, and behavioral health. I'm based near Sedona and offer telehealth sessions, making it easy to connect from wherever you are in the state. I'm currently welcoming new clients who are ready to start working toward their mental health goals in a flexible, low-pressure setting.

With a nursing career spanning since 2008, I have dedicated over 15 years to understanding the complexities of patient care. After earning my Master’s Degree in 2021, I transitioned into advanced psychiatric practice in 2022. Having served in both fast-paced inpatient units and collaborative outpatient clinics, I offer a well-rounded perspective on mental health. My background allows me to blend clinical expertise with a deeply rooted compassion for the human experience.

I am a board-certified Psychiatric Mental Health Nurse Practitioner with extensive experience across inpatient psychiatry, crisis stabilization, substance use treatment, residential care, intensive outpatient programs, and outpatient medication management. My background has given me the opportunity to work with individuals facing depression, anxiety, bipolar disorder, PTSD, ADHD, substance use concerns, mood instability, sleep problems, and life transitions.

Clients often describe my style as calm, direct, supportive, and easy to talk to. I believe mental health care should feel collaborative, respectful, and practical. My goal is to help clients better understand what they are experiencing, explore treatment options, and build a plan that supports real improvement in daily life.

I have a strong interest in treatment-resistant depression, interventional psychiatry, and evidence-based medication management, while also recognizing that each person’s story, goals, and values matter just as much as symptoms or diagnoses.

My name is Jessica Harrison. I am a doctoral prepared, dual-certified Family and Psychiatric Nurse Practitioner.

I have an extensive medical background that includes primary care, urgent care, internal medicine and hospital medicine. My psychiatric experience includes substance abuse, eating disorders, crisis stabilization, and outpatient services caring for individuals with depression, anxiety disorders, PTSD, women's mental health, and bipolar disorder II.

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.

Right now, I spend my days as a psychiatric nurse practitioner helping adults who live with chronic pain and the anxiety, low mood, PTSD, and sleepless nights that so often come with it. Before I became a nurse practitioner, I spent more than 13 years in nursing: in inpatient psychiatry, in psychiatric crisis care, and in medical and neurology units at Mayo Clinic and Barrow Neurological Institute. Today I see adults 18 and older across Arizona by video, including the hard-to-reach corners of the state, on Saturdays and Sundays from 5 AM to 7 PM. I focus on anxiety, depression, OCD, ADHD, and insomnia, and I prescribe non-controlled medications only.

I’m a Licensed Professional Counselor based in Arizona, specializing in trauma, attachment, substance use, and psychedelic integration. I hold a Master’s in Clinical Psychology and am currently completing my PhD in Transpersonal Psychology, where my research focuses on inner healing intelligence, somatic integration, and transformation through altered states of consciousness.

My approach is both grounded and deeply experiential. I integrate somatic therapy, parts work, mindfulness, and attachment-focused interventions to help clients move beyond insight and into real, embodied change. I believe that healing doesn’t come from fixing what’s “wrong,” but from reconnecting with the innate intelligence within you that already knows how to heal.

I work well with clients who feel stuck in patterns they can’t think their way out of—whether that’s anxiety, depression, trauma, relationship struggles, or cycles of substance use. Many of my clients are high-functioning but internally overwhelmed, disconnected, or carrying unresolved emotional pain. Together, we create a space that is honest, supportive, and sometimes challenging—in the service of real growth.

I also specialize in integration work for individuals exploring or recovering from psychedelic experiences. I help clients make meaning of these experiences and translate insights into sustainable, grounded change in their daily lives.

In our work together, you can expect a balance of compassion and accountability. I’ll meet you where you are, but I’ll also help you move forward. My goal is to support you in building a life that feels aligned, regulated, and genuinely yours—not just one that looks okay on the outside.

My name is Benjamin. With over 25 years of experience, I help individuals and couples build stronger, more fulfilling relationships and improve emotional well-being. I work with adults, couples, and families navigating anxiety, depression, PTSD, and other life challenges.

My approach is personalized, collaborative, and focused on meaningful, lasting growth. I help clients better understand their emotions, strengthen connections, and develop practical tools for everyday life.

Therapy with me is real, down-to-earth, and engaging—I bring honesty, humor, and compassion to create a space where you can grow, heal, and be yourself. Book with me here or at https://evolvetothrive9.com.

My name is Carly Reina, and I am a Psychiatric Nurse Practitioner with a Master of Science in Nursing from Walden University. I provide mental health care across the full lifespan — from children, adolescents, adults, and seniors — and I take pride in the breadth and depth of experience that allows me to serve individuals and families at every stage of life.

My primary clinical focus areas include relationships, sleep disorders, ADD/ADHD, anxiety, and depression. I also work with clients navigating bipolar disorder, PTSD, trauma, panic disorders, chronic conditions, OCD, stress, and family concerns.

My work with children, adolescents, and young adults is particularly meaningful to me. Early childhood is one of the most critical and often underserved periods for mental health — and having a provider who understands the unique developmental, relational, and behavioral landscape of these early years can make a profound difference for both children and their families.

Whatever stage of life you or your loved one is in, I am here to provide thoughtful, individualized care.
