Fun Facts

The heart of South Austin is the most interesting place Dr. Redfearn has lived; he enjoyed the welcoming atmosphere and colorful personalities there. Not everyone knows this about Dr. Redfearn, but he went back to school to become a doctor later in life. Previously, he worked in a laboratory environment. As a kid, he wanted to be fireman because being a first responder is about the most direct way you can help someone – and the fire trucks are interesting, too!

​I use the same approach with patients as I would my family or friends: I strive for a relationship that emphasizes honesty and continuity of care. Healthcare should not be looked at as a series of events, but instead as a lifelong process.
