Real Estate Agent

As a local Mendham resident, Cassandra (also known as Cassie) realizes the importance of working with an agent who communicates well and has a deep understanding of the market. Cassie and her family moved to Morris County in 2014 and were immediately impressed with the strong community. As a mother of two young children, Cassie is involved with numerous organizations and continues to stay active with local events, allowing her to provide clients with important information about the area.


With her attention to detail and local knowledge, Cassie offers the personalized service necessary to make sure everyone she works with is happy and satisfied after each transaction. “My clients trust me with one of the biggest decisions of their lives, so it is crucial to listen closely and determine their wants and needs.” Cassie explains. “Clients make the decisions, but it is my job to guide them throughout the process.”

After graduating from Ithaca College as a marketing/ communications major, Cassie spent five years in the entertainment industry in Los Angeles and New York. Most recently, she worked with the Showtime Television Network. Cassie always believed that her marketing expertise would translate well into the real estate industry. After obtaining her license in 2016, Cassie has gained recognition as a dedicated associate achieving Million Dollar Sales levels in a short period of time. Most recently, Cassie was recognized as a 2021 Market Leader within her brokerage.
