Cathi Zillmann, CPNP, PMHNP
Psychiatric/Mental Health Nurse Practitioner
My name is Cathi Zillmann, CPNP, PMHNP, based in Smithtown, NY. My specialty (and my passion) is treatment of ADHD and related disorders in children, adolescents and adults.
I have been a Nurse Practitioner since 1993. My first job was as a pediatric NP, working for the Department of Pediatric Neurology at Stony Brook University. It was there that I first learned of ADHD and by 1995 I was specializing in it. My experiences with children with ADHD inspired me to pursue further education in the psychiatric field to gain a better understanding of how to treat ADHD in both children and adults. I had noticed that people with ADHD also often had depression, anxiety, tic disorders, learning problems, and/or behavior/attitude problems. So, in 2005, I earned my second NP degree, in Psychiatry.
Over the past 20 years, I have worked closely with children, adults and families affected by ADHD, and in several different clinical settings, including; outpatient Pediatric Neurology, a school based clinic, home visitation, and in Mental Health Clinics in Suffolk County.
Out of all of these settings, working with patients in my private practice has been the most rewarding for me, and the most fun, by far.
I also have had the privileged of teaching Stony Brook Nursing Students who are completing their clinical coursework during their training to become Psychiatric Nurse Practitioners.

Timothy P. Aiello is a Psychiatric Nurse Practitioner who joined the practice in June of 2017, after finishing his schooling at Stony Brook University's School of Psychiatric Nursing.
Tim trained under Cathi during his final year of clinical training year, during which they realized their mutual passion for working with children, adults, and families who live with ADHD.
Prior to completing his training, Tim worked as a Registered Nurse at Stony Brook's CPEP, Suffolk County's only state affiliated psychiatric emergency room at Stony Brook University. As such, he brings valuable crisis intervention and emergency room experience to the private practice setting.
