You're smart, self-aware, and honestly pretty good at explaining exactly why you're stuck. You just can't seem to get unstuck. The to-do list exists. The plan sort of exists. And yet — the avoidance, the overthinking, the decision that keeps not getting made. Sound familiar? Anxiety, perfectionism, and big life transitions have a way of quietly running the show. Therapy isn't about fixing what's wrong with you — because nothing is. It's about understanding what's underneath, building some actual tools, and figuring out what you want. Not what everyone else thinks you should.

Hi, I'm Cassie (Cassandra), a board certified Psychiatric Mental Health Nurse Practitioner with over five years of experience in mental health care.

I believe mental health treatment should feel supportive, collaborative, and free of judgment. Every person has a unique story, and I take the time to listen, understand your goals, and create a treatment plan tailored to your individual needs.

I specialize in the treatment of anxiety, depression, ADHD, stress, burnout, sleep concerns, and other common mental health conditions. Through thoughtful psychiatric evaluation and medication management, my goal is to help you find clarity, restore balance, and move forward with confidence.

Whether you are seeking support for the first time or looking for a fresh approach to your mental health care, I strive to provide a comfortable and welcoming space where you feel heard, respected, and supported.

I look forward to partnering with you on your journey toward improved mental wellness and helping you build the tools needed to thrive in everyday life.
