Diane Koester Sibert

When buying or selling, you've come to the expert who can help you!  William Pitt Sotheby's has recently been awarded the #1website for our marketing approach and penetration in the residential marketplace.  

The ability to go above and beyond to help others is my greatest asset.  My personal accountability and knowledge gives you the expertise you will need. I walk you through the process and give you a measure of the marketplace.

When you meet me, I am authentic, have integrity, and am respectful. I work tirelessly, and with a sense of urgency and passion.

When I work with you…”It’s all about you”. I exceed expectations by connecting to your needs while I strive to be the mark of success for everyone involved in the real estate transaction.

I have enjoyed gaining the trust of many high-level executives, parent organizations, peers, and mentors throughout my career and have become known for my work ethic and ability to execute. Trust and confidence are two main attributes to partnership, and my goal is to become a partner with you.

Before entering real estate, I practiced interior design for retailers such as Bloomingdale’s, Victoria’s Secret, La Senza, PINK, and Meijer on large and small scale construction projects.

In 1988, we purchased a small cape style Sears Kit House in New Milford, CT, and renovated it personally with a lot of hard work and tenacity.  In 2001, we designed and expanded our home into a “new old house” in the Federal and Greek Revival style.  In Connecticut we have provided the best quality of life for our son.  He has excelled both academically and athletically becoming quite a hockey player.  

I look forward to working with you in Greater Fairfield County, Litchfield County and New Haven County, in addition to the coordination with our offices worldwide.

Education

Bachelor of Science, Interior Design, University of Cincinnati, College of Design, Architecture, Art and Planning
