Biography

I am a board-certified psychiatrist with more than 25 years of experience and psychiatric training at Johns Hopkins Hospital. I provide compassionate, evidence-based, individualized care, considering each patient’s medical history, experiences, lifestyle, and needs. I evaluate and treat anxiety, depression, ADHD, mood disorders, and stress-related conditions, helping patients find effective treatment and improve their mental health.

I strive to create a warm, welcoming, nonjudgmental environment where patients feel heard and respected. I value open communication and believe in a collaborative partnership that empowers patients to participate in their care. I understand that seeking psychiatric care can feel overwhelming and aim to make the process comfortable and approachable. I combine clinical expertise with compassion to support each patient throughout their mental health journey.

I begin with a comprehensive psychiatric evaluation of symptoms, medical and mental health history, circumstances, and treatment goals. I consider biological, psychological, and social factors to develop an individualized treatment plan. Treatment may include medication management and additional therapeutic support. I explain options, benefits, and risks to support informed decisions. During follow-up visits, I monitor progress, address concerns, and adjust treatment as needed, building a trusting relationship that supports better mental health and quality of life.

Belinda Walsh, PMHNP

Belinda Walsh, PMHNP

Hello, I am Belinda Walsh, a psychiatric mental health and women’s health nurse practitioner. I have been a nurse for over 25 years, working in public health, obstetrics, and psychiatry.

I love working with people and talking with them. My purpose in the therapeutic relationship is to learn about my patient and their goals. I then share my knowledge so we can develop a treatment plan my patient is comfortable with while staying open to their expectations and desires. My primary goal is to help improve a patient’s life so they can be their best selves.

During an initial appointment, I like my client to tell me why they are seeing me, their concerns, and how these have affected their life. I then learn their history, what they have been through, what has or has not helped in the past, and their goals for treatment. Quality care takes time, and sometimes it takes more than one appointment. I will be as informative as possible, working together on realistic expectations and a treatment approach that fits each client’s life.

I take a holistic approach to mental health, recognizing that there is no one-size-fits-all solution. I thoughtfully integrate medication when appropriate, alongside lifestyle changes, sleep, and stress management. I prioritize strong therapeutic relationships and use 30-minute follow-up visits that often include elements of psychotherapy. My clinical interests include mood disorders, OCD, women's mental health, and eating disorders.

In the first appointment, I gather a thorough psychiatric history, explore current symptoms, and learn about the patient's goals. I work collaboratively to develop personalized, evidence-based treatment plans, blending integrative psychiatry with ongoing support for long-term well-being.

I strive to create a respectful environment where patients feel heard as they build a strong therapeutic alliance. I value long-term collaboration to achieve meaningful treatment goals and improve quality of life. With clinical experience guiding my approach, I offer reasonable therapeutic optimism while addressing challenging symptoms and issues. I begin with a comprehensive clinical assessment to understand each patient's symptoms, life story, behavior, and personality, and I develop a collaborative treatment plan, revisiting it over time. Follow-up appointments integrate medication management, if prescribed, and psychotherapy tailored to the individual, using a combination of standard therapeutic approaches aligned with the shared plan.

I earned my medical degree from Vanderbilt University School of Medicine and completed my psychiatry residency at Massachusetts General Hospital and McLean Hospital. I have served on the faculty at Harvard Medical School and Johns Hopkins School of Medicine for over 15 years. I am board certified in psychiatry by the American College of Psychiatry and Neurology.

I emphasize the importance of truly listening, so patients feel seen and heard. I work collaboratively with my patients to identify their main concerns and to build a treatment plan that feels right for them. I believe treatment should be a shared process in which the patient is empowered and supported in their mental health journey. Taking a "less is more" approach to medication, I focus on minimizing prescriptions while still addressing all of a patient's needs. My goal is to help patients eventually rely more on therapeutic skills than medication. I view treatment as a partnership, balancing my expertise in psychiatry with each patient's lived experience.

I bring over a decade of experience in outpatient psychiatric care, with prior roles providing treatment to juveniles in detention and adults in jail and prison systems across West Virginia. I completed my medical degree at the Joan C. Edwards School of Medicine at Marshall University and trained in psychiatry and child and adolescent psychiatry at West Virginia University.

I place a strong emphasis on establishing meaningful relationships with my patients and supporting them in achieving their individual life goals through effective treatment. I actively incorporate patient preferences into all treatment plans and integrate psychotherapy with medication management. I recognize the importance of educating patients about their care and dedicate time during each appointment to address any questions or concerns they may have.

In my clinical practice, I begin by facilitating an open dialogue with patients regarding their primary concerns for the appointment. During initial consultations, I conduct a comprehensive assessment, which includes gathering relevant medical, familial, and social histories that may influence the course of treatment. In subsequent appointments, I engage patients by inquiring about developments that have occurred since their last visit, as well as any issues related to medications or significant life events.

I am a board-certified psychiatrist with a specialization in the treatment of adults aged 18 to 65. I obtained my undergraduate degree in brain, cognition, and neuroscience from the University of Michigan in Ann Arbor. I subsequently attended medical school at Nova Southeastern University in Fort Lauderdale, Florida, and completed my residency training at JFK Hospital in Palm Beach, Florida.

I am a board-certified psychiatrist who takes a warm, collaborative, and evidence-based approach to care. With a focus on treating mood disorders, anxiety, OCD, and substance use, I integrate psychopharmacology and psychotherapy to support patients in achieving meaningful change.

I practice psychiatry through a collaborative, integrative, disability and healing justice-informed lens. I reject oversimplified binaries, recognizing that healing requires embracing complexity. My approach integrates psychiatric and psychotherapeutic practices with complementary, alternative, and natural therapies, as well as harm reduction. My approach is neurodivergence-, queer-, and gender-affirming as well as trauma-informed. Rejecting the binary of "mentally ill" vs. "mentally healthy," I recognize the mind, body, and soul's inherent complexity. My clinical interests include anxiety, OCD, women's reproductive mental health, climate stress, intergenerational trauma, immigrant and refugee mental health, and substance use concerns.

I provide a healing space that prioritizes each service user's goals and lived experiences, and I tailor care to each service user. The first session explores goals, treatment options, and optimal meeting frequency. In many cases, visits are more frequent at the beginning of treatment and spaced out over time. I prefer visits at least every 4–6 weeks and integrate psychotherapy into all treatment plans, with many service users benefiting from ongoing deeper therapeutic work.

My training includes Columbia, Johns Hopkins, and a global mental health fellowship at UCSF.

Based in Tucson, I enjoy desert life, reading, baking, making art, and spending time with my two dogs.

I am a board certified adult psychiatrist who emphasizes patient education and a psychodynamic approach to outpatient psychiatry. My practice focuses on blending medication management together with psychotherapy, and I prioritize collaboration with your therapist, encouraging working together as a team. I understand that medications are not the end-all-be-all of treatment, but just the beginning. For trauma and acute stress, I understand that the journey starts at the tip of the iceberg, with much to explore as you feel more ready. Areas of specialization include psychopharmacology, patient-centered medicine, and combination treatment of psychiatry and psychotherapy.

I am a graduate of the University of Chicago Pritzker School of Medicine, where I completed an MD and PhD combined program, which helped develop my "doctors as teachers" style of practice. I completed my psychiatry residency training at Loyola University Medical Center in Illinois. My passion for empowering patients with knowledge stems from my academic experience in psychiatry residency training. I served as an Associate Program Director of Loyola's Psychiatry residency training program for two years and now maintain an Affiliate Assistant Professor of Psychiatry role with Loyola. I continue to contribute to residency training, as well as mentorship of medical students and psychology externs. Over the years, I have received several awards that demonstrate my affinity for teaching, including the Educator of the Year Award in 2022 from the Loyola Psychiatry Residency Program.
