As a Board-Certified Psychiatric Mental Health Nurse Practitioner, I've dedicated my career to helping individuals find clarity and stability through compassionate, evidence-based medication management. My journey in mental health began with my foundational education at Mount Saint Joseph University, followed by advanced psychiatric training at Purdue Global, where I developed specialized expertise in psychopharmacology—the science of how psychiatric medications work in the brain and body.
I understand that starting or adjusting psychiatric medication can feel overwhelming. Many of my patients come to me after struggling with multiple providers, ineffective treatments, or confusing explanations about their care. I've made it my mission to change that experience. When we work together, you'll never wonder why I'm recommending a particular medication or what to expect from your treatment plan.
My clinical focus includes complex conditions that benefit from careful, individualized medication strategies: ADHD, OCD, personality disorders, PTSD and trauma-related conditions, depression, anxiety disorders, panic disorder, mood disorders, and bipolar disorder. I particularly enjoy working with patients who have treatment-resistant symptoms or multiple diagnoses—situations that require creative problem-solving and a deeper understanding of how medications interact within your unique system.
What sets my approach apart is the time I invest in truly understanding you. I'm here to provide clear guidance and consistent support throughout your journey toward better mental health.

"If you think about it, there is no actual health without good mental health, and I work to help my clients achieve both."
Using the tools of Psychology as well as Psychiatric medication management (if appropriate), you can feel much better, function much better at home, work, and when you find yourself in those uncomfortable times.
Almost every symptom or unwanted trait can improve and in many cases, resolve completely, but only if you give it a chance.
