I just wanted to comment on the Postmaster at this location. We had an issue with the delivery of a package. Jim came to our home to personally fix the issue. He went above and beyond what was expected. He clearly takes his job seriously, and we greatly appreciate the immediacy he gave to fixing our issue. Thank you again, Jim!
