Mustang Creek Estates Residential Assisted Living is planning to open its fourth assisted-living house in January at 1200 W. Main St.

The assisted living facility opened its first house in early May and has opened two more in the months since, Samantha Blossom, director of sales and marketing said.

"We are doing really well," Blossom said. "Our houses are nearly full—that's why we need to open the fourth."

Blossom said there are openings available in the fourth house, and Mustang Creek Estates is also taking reservations for the fifth house.

Mustang Creek Estates plans to open a total of six assisted living houses. Each has 14–16 residents per home.

The business has assisted living homes in Frisco, Allen and Keller.
