Sarah Paston

PMHNP

My background in mental health includes the use of Psychedelic medicationstreatment-resistant depressionanxietyADHD, and women’s mental health care. I received my PMHNP from SUNY in 2018 but have been in medical practice for over 12 years. I am also a mom of twins who are now in their twenties, which gives me unique insight and empathy into how parenting challenges can contribute to mental wellness. Also, I am passionate about animals. I currently have a senior disabled Chihuahua who has her own wheelchair and a blind Shih Tzu. 

My holistic psychiatry philosophy is that mental health and physical health are tightly connected and we can go at the speed you're comfortable with. I am a humanistic provider who listens to your concerns, collaborates with you to create a treatment plan that will work with you and for you, and a psychopharmacologist who can explain in simple language how different medication classes work. We will go low and slow and make one modification at a time to ensure we tailor an effective plan.
