I work with adolescents and adults experiencing depression, anxiety, ADHD, bipolar disorder,and personality disorders
Hello, and welcome. My name is Leane, and I have been a nurse for nearly 20 years. I began practicing as a Nurse Practitioner in 2016 and hold dual ANCC board certifications in Family Practice and Psychiatric Mental Health. My clinical training and experience allow me to approach care from a comprehensive, whole-person perspective. I strongly believe that mental and physical health are deeply interconnected, and that the brain—like the heart—is an essential organ that sometimes requires thoughtful support and treatment. This holistic philosophy guides my work in assessing, diagnosing, and managing psychiatric conditions.

FAQ - About Adult Psychiatry
What does an adult psychiatrist do?
Psychiatrists are medical professionals trained to diagnose mental health conditions and prescribe medications as part of treatment. What differentiates psychiatrists from other types of mental health professionals is their ability to prescribe psychiatric medications. These medications can be a vital part of treatment for many individuals, helping to regulate mood, reduce anxiety, improve focus, or manage intrusive or distressing thoughts. Some adult psychiatric providers may also provide psychotherapy as part of treatment. When seeking care, it’s important to understand whether you’re looking for integrated therapy and medication management or primarily medication support.

While psychiatrists can treat individuals across the lifespan, adult psychiatrists specialize in working with individuals aged 18 and older. This distinction matters because the presentation and symptoms of mental health conditions can differ between adults and younger populations. For instance, disorders such as major depressive disorder (MDD), generalized anxiety disorder (GAD), bipolar disorder, and schizophrenia can present differently in adulthood and may require different diagnostic criteria or clinical judgment compared to children and adolescents. Adult psychiatrists are trained to assess these conditions in the context of adulthood and the co-occurring issues adults may face, such as medical conditions, occupational stress, or relationship difficulties. Treatment approaches may also vary depending on a psychiatrist’s age specialty. For example, adults may benefit from different types of medications or therapeutic approaches than those used with younger clients.

How do I know if a psychiatrist is the right fit for me?
When searching for a psychiatrist, consider their areas of expertise and the populations they typically treat. Some psychiatrists focus on common adult conditions like anxiety or depression, while others specialize in areas such as trauma, substance use disorders, or obsessive-compulsive disorder. If a provider’s focus includes school-related behavioral issues or developmental conditions, they may primarily work with children or adolescents and not be the best fit for adult clients. To ensure a good fit, discuss the psychiatrist’s typical session structure, therapeutic approach, and whether their care aligns with your current needs—especially if you are also working with a therapist or other mental health professionals. Understanding how they incorporate social context, medical history, and adult life circumstances into treatment planning can also help gauge compatibility.

How do I find a psychiatrist?
Psychology Today’s online directory allows you to search specifically for psychiatrists (MDs) and psychiatric nurse practitioners (PMHNPs) who work with adults. Each provider profile includes key information such as clinical specialties, therapeutic approaches, licensure, accepted insurance plans, languages spoken, and session fees. Reviewing these details can help you determine whether a particular provider aligns with your needs and preferences.
