Addiction therapists & psychiatrists in Casselberry, FL

Hi! I am Katie. I am an Licensed Clinical Social Worker (LCSW) and a Masters Certified Addictions Counselor (MCAP). I received my bachelors from UF and then went on to get my Masters in Social Work (MSW) from USF. I have nearly 10 years of experience working in the helping profession. After graduation, I began working in child welfare and for the past 3 years I have been working in residential substance use and trauma treatment programs.

I am a Board-Certified Psychiatric Nurse Practitioner with 26 years of nursing experience in various capacities, including psychiatric mental health and addiction medicine for the last 8 years. My passion is to walk alongside my patients on their mental health journey, helping them navigate challenges, cultivate lasting wellness, and restore balance for a meaningful and fulfilling life.

I have more than 25 years of experience assessing and treating adolescents, adults, and families. While I appreciate numerous approaches, my patients have stated that I provide a melding of both direct and indirect styles. In other words, my standard of care is challenging and supportive. More often than not, you won’t leave a session wondering what’s next.

Whether you are feeling overwhelmed, stuck, or simply seeking personal growth, I’m here to walk alongside you in this therapeutic process.

I look forward to connecting with you.
