    Dr. Weir is a good listener, and was completely up to date on my latest test results and treatment from all my doctors in the Virtua and Penn Medicine health network. This is a major advantage of having all of my doctors under the same umbrella. In our discussion, we were able to craft an activity strategy suitable for me. Greatly pleased overall.

    Dr Mark Weir is an extraordinary doctor, smart, caring and capable! He took care of all my concerns and knowing I was anxious about a specific test he called me personally to tell me my results are Normal. Even when he is very busy he takes the time to make sure everyone gets the best care in a caring way. I feel so lucky to have such a great Pulmonologist and I'm breathing better because of him. The staff is wonderful, especially [REDACTED] ! Thanks to everyone at this great medical office !

    The staff was very attentive in addressing my concerns, my questions. When I first arrived, I was able to check in right away. And the lady who helped me, I actually had an extra request for her because I couldn't reach my zipper. And she was more than accommodating and came from around the back and helped me with my zipper. So I was extremely appreciative of that. The doctor addressed all my concerns answer to my questions. And so I was very pleased with the experience. Thank you.
