What this means for your family

This facility offers an excellent rehabilitation gym and a very active social program that can greatly aid recovery. However, the recurring reports of understaffing and medication errors are significant risks; if you choose this facility, ensure you have a family member present frequently to advocate for your loved one and monitor their care.

Key Review Excerpts

The best part is the rehab therapy staff. They worked very hard and were skillful in getting my strength back and getting me walking again.

Rehab patient · 2023★★★★★

The staff was shockingly underwhelming. They appeared disengaged, unfrie... They repeatedly messed up their meals to the point that I had to bring food every single day.

Family member · 2026☆☆☆☆

At one point, my dad was left sitting in a soiled diaper the entire day because one was available to assist him. Even more concerning, his medications were mismanaged.
