About Visiting Angels, the Leading Senior Care Provider for Families in McKinney, Allen, Frisco and Plano, TX

Our in-home senior care agency proudly serves the adults and seniors in Allen, McKinney, Frisco, Plano and surrounding communities throughout Collin County, TX.

Scott and Theresa Kolp have been married for over 20 years and are the proud parents of three amazing children who all grew up here in the McKinney area. Together, they started Visiting Angels McKinney in 2008. Since then, they have grown to become one of the most tenured and respected senior care agencies in the entire area, having helped hundreds of families in and around Collin County. Their goal from the beginning was simple: to give seniors in their community the ability to age gracefully in the sanctuary of their own homes. It's a mission they take very seriously and a mission that they intimately understand.

Scott and Theresa both dealt with very difficult situations with their own parents in which they had to utilize outside help in order to help them continue living comfortably at home. They quickly discovered the critical need for better, safer and more competent senior care assistance and made the life-changing decision to open Visiting Angels McKinney.

If you or your loved one believe that you could benefit from our in-home care services, please call 214-491-1999 or fill out our contact form.
