Addiction therapists & psychiatrists in Jacksonville Beach, FL

Making the decision to start therapy is a profound investment of your time, energy, and vulnerability. If you are looking for a blank-slate clinician who simply nods and listens, we might not be the best fit. I offer a highly engaged, malleable, and unflinching partnership.

My approach is rooted in the belief that while the work of untangling our lives is deeply structural, the room itself doesn't always have to feel heavy. I bring a grounded warmth to my practice—which means knowing how to sit quietly in the gravity of a difficult truth, but also knowing when to break the tension, exhale, and find the light in the sheer complexity of being human. I won’t just sit in silence while you do all the heavy lifting; I am an active collaborator who adapts to exactly where you are.

I am Sandra MacSweeney, MHA, FNP-C, PMHNP-C, APRN, a dual-certified family and psychiatric mental health nurse practitioner. I lead BFF Clinic — Behavior Functional Focus, with care in the Sarasota and Port Charlotte area and in Volusia County, including New Smyrna Beach and DeLand. I have more than 20 years in healthcare.

I treat depression, anxiety, ADHD, PTSD, bipolar disorder, OCD, sleep disorders, and related conditions, in person and by telehealth, including evenings and Saturdays. Visits are available in English, Spanish, and Portuguese. My training covers both medication management and the medical issues that often sit underneath psychiatric symptoms: hormones, thyroid, nutrition, inflammation, and metabolic health.

I believe therapy is most effective when clients feel heard, respected, and supported. I work primarily with adults and specialize in health psychology, using a biopsychosocial perspective to understand the connection between physical health, emotions, and overall lifestyle. I specialize in supporting clients navigating Anxiety, ADHD, Depression, Sleep disorders, and Stress management. I provide compassionate, patient-centered care in a collaborative and nonjudgmental environment where clients can build resilience and create meaningful, lasting change.

Hi, I’m Katherine! I’m a warm, down-to-earth clinician who believes therapy should feel like a conversation with someone who genuinely gets it—not a place where you feel like judged or lectured. I’m a big believer in being able to laugh together when the moment calls for it, while also making space for the hard stuff. I’m caring but goal-oriented, and I’ll work with you to figure out what you want to get out of therapy and help you take steps toward getting there.
