Welcome!

As a licensed Marriage Family Therapist (LMFT), I believe in prioritizing out mental health as a way to live a happy and balance life. Reaching out for help can be one of the hardest things a person can do, great job on taking that step! I’ve been practicing for 10 years, but in the field for 20 plus years. In the last 6 years I have shifted my main focus to adults 18 plus who are struggling with trauma and substance use.

My goal is to create a space where you feel seen, understood, and supported. I believe mental wellness is an essential part of overall health, and that healing begins by moving from survival to thriving through nervous system regulation, processing past experiences, and strengthening the mind-body connection. Meaningful change and healing happens within a strong therapeutic relationship built on trust, authenticity, and collaboration. Whether you're navigating anxiety, depression, trauma, relationship challenges, addiction, performance anxiety, work-related stress... or simply feeling overwhelmed by life's demands, we'll work together to build insight, process difficult experiences when appropriate, develop practical coping skills, and create meaningful, lasting change.

As a Psychiatric Mental Health Nurse Practitioner (PMHNP), I’m trained at the graduate level in mental health care across the lifespan. I assess mental health concerns, diagnose conditions, prescribe and manage psychiatric medications, and provide psychotherapy. I also coordinate care with therapists, primary care providers, and other specialists as needed.

I am currently accepting new clients. Life can feel loud, confusing, or just plain heavy, and you do not have to sort through it alone. I work with children, teens, and adults navigating anxiety, depression, ADHD, autism, mood changes, personality-related struggles, and big emotions. Whether you are looking for support for your child or for yourself, our work can help you feel more understood, more steady, and better equipped for everyday life.

As a therapist, I am passionate about walking alongside folks as they reveal their truths and vulnerabilities to themselves. I believe, and have witnessed that people are capable of long standing change with knowledge, support, and connection, and that therapy is a great place for that. You can learn new ways to manage life stressors, feel safe, gain confidence, and live a more joyful and purposeful life. I use cognitive behavioral, solution-focused, and strength-based techniques, while never ignoring the human element and connection where the real change happens.
