Two new businesses will fill the East Wareham storefronts that were vacated when TJ Maxx and Staples opted to move to Wareham Crossing.

The Hawthorn Kidney Center, a kidney dialysis treatment center, will open up by mid-December in the old TJ Maxx, which was located next to Stop & Shop, according to Jeff Dale, vice president of project management for the Beverly-based American Renal Associates, the major partner in the center's ownership.

Across the parking lot in the old Staples building, Tractor Supply, a store for hobby farmers, will open by early November, said Jim Schindley, Southern New England district manager for that store.

The Hawthorn Kidney Center, which will take up about a third of the space that TJ Maxx did, will provide kidney dialysis treatment for patients suffering from hypertension, diabetes, and other conditions that create a need for dialysis, Dale said.

"It can be for anybody, but generally, it is for an older population ... and people with long-term ... diabetic conditions," Dale said.

American Renal Associates decided Wareham would be a good location for its center after talking to its physician partners in the area.

Construction is planned for mid-September. The entrance to the facility will be to the rear of the building, and will give easy access to patients who need to be picked up or dropped off, Dale said.

Patients need "to be able to get there," Dale said. "They go three times a week, [sometimes] they are there for four hours. So you have to make the time [spent] to ... get to the facility a convenient experience."

Tractor Supply provides goods such as livestock feed, gas compressors, and lawn mowers.

Fun fact: Tractor Supply sells almost everything except tractors. Schindley explained that the name comes from its beginnings, when the store was founded as a mail-order parts supply store.

Schindley said that the company uses a complicated formula that calculates certain factors in the area, such as the population of horses and cattle and the number of pick-up trucks, when it chooses where to open a store.

Wareham fit the bill.

Many Wareham residents already frequent Tractor Supply's store in Taunton, Schindley added.

The store will hire approximately 15 people, with the goal of having all employees from Wareham and the local area, Schindley said. Two employees, a manager and assistant manager, have already been hired and are local, Schindley said.

The store will take up the entire 18,000-square-foot former Staples building. Goods will also be sold in a 20,000-square-foot yard space in the parking lot in front of the building.

The Nashville, Tennessee-based Tractor Supply has more than 11,000 stores all over the U.S.
