Key Review Excerpts

The other day we came to visit Mom (Enid) and of course Lyla, as always, had a wonderful smile to greet us and when we had lunch Mario treated us, and especially Mom, as royalty.

Resident's family · 2024★★★★★

The staff members are friendly and helpful. They hold the elevator doors for me. I like the updated information about the current activities. They are usually posted on the walls and inside the elevators.

I can tell this staff is committed to providing the best experience possible for residents, family, volunteer, and healthcare providers alike. Mary Schwartz Summit has taken the safety and security of their residents as a primary focus.
