Fantastic staff, always knowledgeable, helpful and kind. I’ve been coming here for years and I go out of my way to use this post office because of the excellent employees and quick service. Small, hometown feel in the middle of Morris county

Key is a total rockstar! We came in for our daughter’s passport renewal (after our Morris Plains appointment fell through because all of their passport staff called out), and Key had us in and out in just 15 minutes. Thank you again for making the process so quick and easy.

I can not tell you what a wonderful experience we had at the Post office. Key and Ron are the best .I needed to apply for a Passport and went to several post office 's with not a good experience. I highly recommend Cedar knolls, they were friendly, knowledgeable, and kind. Thank you for all your patience and help!
