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.

I’m a board-certified Family Psychiatric Nurse Practitioner and former Navy Corpsman with over 20 years of medical experience. My background spans oncology, ICU, and community mental health, which allows me to care for clients across the lifespan—from children to older adults—with a well-rounded, compassionate perspective.

I take a holistic, patient-centered approach, focusing on truly understanding your unique needs and goals. In addition to treating conditions like anxiety, depression, ADHD, trauma, and mood disorders, I offer advanced treatment options such as Medication Assisted Treatment (MAT), hormone therapy, and ketamine infusion therapy for those who haven’t found relief with traditional approaches.

Therapy with me is very human and genuine. I don’t just focus on what’s painful or stuck but help to highlight the ways in which my clients overcome life's punches. While I take this work seriously, I believe laughter can be healing and disarming in therapy.

I earned my Master’s degree in Counselor Education from Florida International University and have worked in a variety of settings, including the foster care system, residential treatment, and community mental health. My background includes supporting individuals navigating trauma, persistent mental health conditions, substance use, eating disorders, and major life transitions. I’ve also worked with veterans, individuals who are unhoused, and LGBTQIA2S+ clients.

In my practice, I work with clients experiencing anxiety, panic, depression, trauma, identity exploration, relationship challenges, and life transitions. I also support clients with PTSD, some OCD presentations, and concerns related to gender, sexuality, and queer identity. My work is trauma-informed, affirming, and rooted in helping clients feel both emotionally safe and genuinely understood.

I believe that seeking mental health care is a courageous step, and I strive to create a welcoming, supportive, and judgment-free space for every client. My goal is to ensure you feel heard, understood, and comfortable throughout your treatment journey. Together, we will work collaboratively to develop a personalized treatment plan that supports your unique needs and goals

My goal is to help you overcome the challenges you are facing in a safe and comfortable environment to help you improve your quality of life. My passion is helping those with substance use disorders, including alcohol and opioid use disorder, safely detox from the substances and work towards a meaningful and long-lasting recovery. With a decade of experience serving a wide range of patients I am a dual-certified family nurse practitioner and psychiatric mental health nurse practitioner.
