Welcome to My Practice – I'm Tina Fast, CNP, PMHNP-BC, PNP-BC

Yes, Fast really is my last name—and with over 25 years of experience in healthcare, I’m proud to be a dual-certified Nurse Practitioner in Pediatrics and Psychiatric Mental Health.

From a young age, I felt called to care for others. I began volunteering in special education classrooms in elementary school, where I discovered my gift for compassion. By high school, I became a medical assistant, working first in OB/GYN and then in pediatrics—an experience that solidified my path. I shifted from pre-med to nursing, and never looked back.

I earned my RN in 2004, working in postpartum care before becoming a public health nurse with the Nurse-Family Partnership, a program supporting first-time moms from pregnancy through early childhood. Building relationships and providing support during their most vulnerable times was incredibly meaningful.

In 2010, I became a Nurse Practitioner and have since served in diverse settings, including child abuse programs, SANE (Sexual Assault Nurse Examiner) care, school-based clinics, public health, and private practice. Each experience has deepened my commitment to holistic, patient-centered care.

As a mother of four—including three neurodivergent children—I understand firsthand the challenges many families face. My personal and professional journeys have taught me that healing isn’t linear, and that everyone deserves compassionate support along the way.

Whether you're here for your child, yourself, or your family, my goal is to walk alongside you with empathy, clinical expertise, and respect. We’ll work together to find the best path forward—tailored to your unique needs and goals.

I’m honored to be part of your journey.
