Addiction therapists & psychiatrists in Sarasota, FL

Hi, I’m Casey. As a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) and the founder of Nexus Psychiatric Services, I built this practice for people seeking exceptional clinical care from an approachable, down-to-earth provider.

My professional foundation comes from my years of experience in the acute inpatient psychiatric setting. Navigating these high-intensity settings taught me to bring calming stability to those who are struggling, and I carry that into every outpatient telehealth visit. Today, my practice supports adults, adolescents, and children ages 6 and up through the everyday challenges that arrive when living with diagnoses such as anxiety, depression, and mood disorders. Beyond general psychiatric care, I offer a deep clinical commitment to neurodivergent individuals and those suffering from identity issues. Whether you are feeling exhausted by life, exploring your identity, or trying to help your child thrive, you are welcome to show up to our sessions exactly as you are.
