Location and Directions


My husband and I were away for the weekend from NY to PA. He had a bad cough for a while but it got worst very fast. It was scary being away from home and Our Doctor. We found St Mary’s Hospital and were beyond relieved with this hospital. The doctors, nurses, PA, etc were amazing; they were kind, efficient, fast and made us feel so comfortable to be in such capable hands. He was quickly diagnosed with pneumonia and was treated immediately! I wish we could thank everyone individually, but instead a huge Thank you to all! (in the last week)

I've always loved this hospital. I'll never come here again! Who ever started doing the hiring here should be fired! (4 weeks ago)

I had my daughter here last year and I felt SUPER COMFORTABLE. All the of staff were amazing and very kind and the hospital itself was clean and tidy. (2 months ago)

What an awful hospital they have become. I’ve been coming here for over 20 years but only because there weren’t any better options offered in the immediate area. I can say with great certainty that they have been on a steady decline over the last 20 years. I could write a book as to what is wrong with this place but it boils down to very very rude staff, extreme wait times, complete lack of any type of logistically streamlined processes, and clear greed. Instead of worrying about building new shiny additions, they should focus on the people they are supposed to be here for, and actually hire some staff members that don’t clearly hate their lives and jobs. Only reason I kept coming back here was because of the close proximity to my house, but after this last experience, I’ll suck it up and make the drive to either the city (Philadelphia), or Doylestown. Do yourself a favor and avoid this place at all costs. Unless you wanna wait in their waiting area for about 3 hours only to be treated like a piece of garbage. AWFUL 👎👎👎 (4 months ago)

Very poor response times. After 6 hours in the waiting room I was brought back to room to wait another couple hours before being even seen by anyone. For all the staff knew I could of been dead. Don’t go to this ER unless you want to suffer. They need more staff and doctors in a bad way. Will never come back. (3 months ago)
