Katie Brussack

Clinical Director of Amethyst Recovery Center

Katie Brussack is the Clinical Director of Amethyst Recovery Center in Port St. Lucie, Florida, one of USR’s expert treatment centers for substance use and co-occurring disorders. Both personal experience and a lifelong curiosity about the connection between addiction, trauma, mental health, and human behavior shaped her passion for behavioral health. Growing up, she witnessed her mother’s recovery journey after achieving sobriety when Katie was 10 years old, giving her an early understanding of the hope and transformation that recovery can bring. Her father also served as a firefighter, paramedic, and EMT for 31 years, inspiring a deep respect for first responders and the challenges they face. These experiences led Katie to earn a Bachelor of Science in Psychology followed by a Master’s degree in Mental Health Counseling.

As a therapist, Katie is passionate about creating a safe, supportive environment where clients can embrace vulnerability, challenge unhealthy thought patterns, and build healthier beliefs about themselves. She finds great fulfillment in helping clients develop self-worth, self-compassion, and hope while working toward lasting emotional wellness, recovery, and meaningful personal growth. She also has a special passion for supporting first responders and individuals navigating addiction and co-occurring mental health challenges.

One of Katie’s most meaningful personal milestones came in 2025 when she had the honor of presenting her mother with her 27-year sobriety medallion. That experience continues to reinforce Katie’s belief that long-term recovery is possible and inspires the compassionate, hopeful approach she brings to every client relationship.
