About Us

We are a newly rejuvenated group of caring and interested neighbors trying to help our community become the best that it can be. We are deeply committed to improving our quality of life in all aspects including: community involvement, diversity, and safety. Our goal is to include as many residents – both owners and renters – in the decision making process, and more importantly, in getting involved. We are organizing neighborhood events and meeting for the first time in many years and hope that this is just the beginning of a welcoming and all inclusive community-based partnership. We value all opinions, suggestions, concerns, and recommendations. Please come join your fellow neighbors working together to celebrate and improve Centennial!
