My name is Suzanne Simmons. I am a board certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC). I treat patients of all ages. I have worked in healthcare for over 20 years. I spent most of my nursing career as an Intensive Care RN. I’ve always held an interest in helping those that are the most vulnerable. I chose psychiatry to help people achieve the best version of themselves. During my evaluation you will expect a thorough assessment including an extensive personal history and lab testing.

Dr. Suzanne Simmons is one of my favorite doctors. I had been under another doctors care and once Dr Simmons took over she changed and/or eliminated meds I then realized were causing me harm physically, mentally and emotionally… Dr Simmons made all the difference for my well being!
