Dr Willis is your "old fashioned" practitioner. He ask questions and listens to your response! Takes the time your visit requires. His staff is professional yet personal.

Old fashioned Doctor. You'll get this if your a Gunsmoke TV show... he's Doc!
in Arlington, TX |
Very honest and caring. Not afraid to tell a person no.
in Alvarado, TX |
Rude desk staff, refused treatment despite my husband being an established patient. Would not make an appointment for diabetic care because we revealed he may be having additional issues. Will be filling a formal complaint with medical board for refusing care.
