Hi, I’m Ari, the founder of Cotallat Psychiatry. I’m a Psychiatric Nurse Practitioner and NYU graduate with several years of experience in mental health. I started Cotallat Psychiatry with the goal of creating a practice that feels personal, approachable, and centered around each client’s needs. I really value getting to know the person behind the symptoms and making sure clients feel comfortable being open, asking questions, and taking an active role in their care. Outside of work, I enjoy staying active, traveling, reading, and watching movies. My goal is to make treatment feel supportive, realistic, and focused on what works best for each person.

Selina Correa

Administrative Assistant

Selina, who goes by Sel, serves as the Administrative Assistant at Cotallat Psychiatry and is often the first person clients speak with when getting started. She helps with scheduling, insurance questions, messages, emails, and calls, and also conducts our initial phone consultations. Because of this, many clients have a chance to meet Sel before their first appointment with a provider. She also serves as a point of contact when providers are unavailable and helps keep communication organized along the way. Sel’s goal is to make the process of starting and continuing care feel as easy, clear, and stress-free as possible.
