I believe good mental health care is about more than checking off symptoms on a list.

As a dual board-certified Psychiatric Mental Health & Adult-Gerontology Nurse Practitioner, I look at the whole picture—your mental health, physical health, sleep, hormones, nutrition, movement, stress, and everything else that may be affecting how you feel.

I listen first, then we work together to create a treatment plan that makes sense for your life. No one-size-fits-all approach. Just thoughtful, individualized care focused on helping you feel better and stay well.

Healing Across the Lifespan: A Partnership in Mental Wellness

Choosing a mental health provider is a deeply personal decision. You aren’t just looking for a prescriber; you are looking for a witness to your story, an expert in the biological complexities of the brain, and a partner in your recovery.

My name is Jessica Stanley, and I am a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC). My journey to this practice has been defined by a unique duality: the macro view of a healthcare executive and the micro focus of a dedicated clinician. Before opening the doors to this practice, I served as the Clinical Director for a large-scale healthcare organization. In that role, I was responsible for the oversight of complex systems, the mentorship of large clinical teams, and the implementation of evidence-based protocols across diverse populations.

While my time in leadership allowed me to impact mental health at a systemic level, my true passion has always remained in the quiet, transformative moments of the exam room. I have returned to full-time clinical practice to bring that high-level expertise back to where it matters most: the individual human experience.

Mental health does not exist in a vacuum, nor does it look the same at age seven as it does at seventy. I specialize in treating patients across the entire lifespan. Whether I am working with a child struggling to navigate their first years of school, an adolescent facing the pressures of identity formation, or an adult managing the heavy mantle of career and family, my approach remains the same: comprehensive, compassionate, and evidence based.
