Here at Primary Care Plus, our name and practice are new, but we are a long-established group of medical professionals with years of background in primary care. Dr. Clovis Manley has practiced in the Evansville / Newburgh area since completing his family practice residency at Deaconess Hospital in 1990. Kathalene “Katie” Keller NP-C had 12 years of experience in the emergency department before becoming a nurse practitioner 5 years ago and switching her focus to family practice.
