Three Dayton-area Kroger stores are adding health clinics staffed by nurse practitioners.

The clinics are operated by Nashville-based The Little Clinic, a subsidiary of Cincinnati-based Kroger which operates 85 clinics in Kroger-owned grocery stores in Ohio, Kentucky, Tennessee, Georgia, Colorado and Arizona.

Officials from Kroger, The Little Clinic and the city of Kettering gathered Monday afternoon for a ribbon-cutting ceremony at the newly opened clinic inside the Kroger store at 2115 E. Dorothy Lane in Kettering. A similar clinic opened last week at the Englewood Kroger at 885 Union Road, and a third clinic is scheduled to open Sept. 5 at the Beavercreek Kroger at 3165 Dayton-Xenia Road, according to Kroger and Little Clinic officials.

The clinics are open seven days a week, and no appointment is necessary.

The certified nurse practitioners who see patients are authorized to diagnose and write prescriptions for common illnesses such as seasonal allergies, sinus infections, bronchitis and influenza, Kroger and Little Clinic officials said. Additional services — including physicals required for students to attend sports and band camps — also are available.

“Kroger has been in the pharmacy business for a long time, and we wanted to take the next step toward offering a more complete health-care package,” Kroger spokeswoman Rachael Betzler said.

The new clinics are not the first health clinics to operate inside Kroger stores. Premier HealthNet leased space from Kroger to open a clinic in the Englewood grocery store in late 2008, and also operated similar clinics in Kroger stores in Beavercreek and Kettering. Those clinics closed in 2011, Betzler said.

The Kettering store is the 14th Kroger store in the Cincinnati-Dayton market to include a clinic, and the grocery chain is looking to expand the concept into existing stores, if space is available, and into newly constructed groceries, Betzler said. Officials with The Little Clinic say no decision has been made yet on whether to include a clinic in the Kroger store under construction in the Austin Landing development in southern Montgomery county.
