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.
