Why “CardinaLight”?

Many believe that when a cardinal appears, an angel is near.  The name of our practice, CardinaLight, was born with this thought in mind.  My father left behind a legacy that is filled with love, faith and purpose and we wanted to honor this in an endeavor I know that he would have completely supported.  Our practice logo is representative of me and my father in a brakeman’s lantern, a lantern my paternal grandfather used throughout his career, and a lantern that was present in our home my entire childhood.  CardinaLight Health, LLC hopes to be a medical practice that will embody that love, faith and purpose.
