I am a PMHNP-BC, board-certified Psychiatric Mental Health Nurse Practitioner, dedicated to providing compassionate, evidence-based mental health care for adults and adolescents. I combine clinical expertise with a holistic, faith-informed approach, emphasizing collaboration, education, and individualized treatment planning.
I’m a psychiatric nurse practitioner who works from the belief that people are not broken—and that many of the struggles we call “mental illness” make sense when we look at trauma, context, and lived experience. I’m especially attuned to the ways mental health systems, stigma, and labels can unintentionally cause harm, and I aim to practice in a way that feels respectful, collaborative, and deeply human.
My approach is unconventional and trauma-informed, influenced by perspectives like those of Gabor Maté, which emphasize compassion, curiosity, and understanding symptoms as meaningful responses rather than defects. I do not believe in rushing to pathologize the human experience. As Joni Mitchell once reflected about depression, sometimes what we’re feeling is not an illness to be fixed, but a signal—an honest response to pain, loss, or a world that has not been kind.
Hello! I'm Idowu Mary Oni, a Board-Certified Psychiatric Nurse Practitioner (PMHNP-BC) committed to delivering personalized, compassionate mental health care. With a strong foundation in nursing, I specialize in supporting individuals as they navigate mental health challenges and work toward greater emotional well-being. I'm honored to be part of your journey and look forward to helping you reach your goals with care and understanding.
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.

Factors to Consider When Choosing a Therapist in Longmont
Searching for psychiatrists in Longmont starts with understanding what kind of care fits your needs. Psychiatrists and psychiatric mental health nurse practitioners can diagnose mental health conditions, prescribe medication, and manage medication over time. Therapists provide talk therapy and may work with you on concerns such as anxiety, depression, ADHD, bipolar disorder, obsessive-compulsive disorder, stress, or life transitions. Some people start with a psychiatrist, some start with a therapist, and some work with both. As you compare options, look for a psychiatrist whose listed specialties, clinical background, and approach match the care you want.
In a smaller city like Longmont, local psychiatry appointments may be more limited than in larger Colorado markets, so virtual appointments can expand your options. Medication management visits are usually shorter and less frequent than therapy sessions, while some psychiatrists also offer therapy as part of care. When narrowing your search, consider appointment availability, whether the psychiatrist is accepting new patients, and whether they offer a free phone consultation. Reading bios before booking can help you understand how a psychiatrist communicates, what they focus on, and what to expect from sessions.
Psychiatric care in Longmont can be a significant expense without insurance. Using in-network insurance is one of the most reliable ways to reduce session costs and understand what you may pay before your first appointment. Headway makes this easier by helping you find psychiatrists who match your preferences, take your plan, and are accepting new patients. You can enter your insurance details, review estimated costs upfront, compare 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.
