Recognizing the need for growth and change can feel intimidating, but taking that first step toward therapy shows courage and a willingness to invest in yourself. I create a warm, supportive space where clients can safely explore past and present experiences. Together, we work to understand patterns, emotions, and challenges that may be holding you back. I view therapy as a collaborative journey where we move at your pace while building insight, self-acceptance, and meaningful change. My goal is to help you reconnect with your strengths and move toward a more balanced, fulfilling life.
I am a Licensed Professional Counselor with extensive experience working with children, teens, adults, and families. I specialize in trauma, anxiety, depression, relationship concerns, and emotional regulation.

Finding the right mental health provider can feel overwhelming, especially if you've tried therapy or medications in the past without getting the relief you were hoping for. My goal is to help you move beyond simply managing symptoms and toward feeling like yourself again.
I am a dual-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-C) with over 16 years of healthcare experience. I specialize in treating adults with depression, anxiety, trauma, ADHD, insomnia, OCD, and treatment-resistant mood disorders. My advanced psychiatric training was completed through Monmouth University and Wilkes University, where I focused on Evidence-based psychiatric care.
I believe that effective treatment starts with understanding the whole person not just the diagnosis. Together, we'll explore the biological, psychological, and lifestyle factors contributing to your symptoms and develop a personalized treatment plan that fits your goals. My approach combines thoughtful medication management with practical therapeutic strategies that you can apply in everyday life.
For individuals whose depression has not improved after trying multiple antidepressants, I also evaluate and provide treatment options such as Spravato (esketamine) when clinically appropriate. My focus is always on finding the safest, most effective treatment based on your unique needs.
Patients often describe me as warm, approachable, honest, and solution focused. I strive to create a supportive, judgment-free environment where you feel heard, respected, and actively involved in your treatment decisions. Whether you're seeking help for the first time or looking for a new approach after previous treatments haven't worked, I'm committed to helping you build lasting emotional wellness and improve your quality of life.
