Our Story
WellMind Psychiatry was founded with a simple but urgent mission: to raise the standard of mental health care. Too often, people seeking help face long waits, rushed appointments, and care that feels impersonal or outdated. We knew there had to be a better way.
Drawing on over 15 years of medical experience, our founders set out to create a practice where evidence-based treatment meets genuine human connection. Here, you won’t wait months to be seen or feel like just another case file. We prioritize timely access, thorough evaluations, and care plans tailored to your unique needs.
Today, WellMind is proud to serve patients across multiple states—and we’re growing. Soon, you’ll be able to connect with our team through convenient e-visits, bringing compassionate, professional care right to your home.
WellMind exists because you deserve both clinical excellence and personal attention—without compromise.
