Shannon brings 23 years of experience as a business project manager at Cigna Healthcare to Buttonwood. She focuses on improving the way we work together and improving the client experience. When we work better, we work better for you.

“ I love doing the work that is rarely seen but makes the team shine. Someone needs to focus on business practices and a culture of excellence, let it be me.”


Before moving to Maryland, Shannon spent her early years in Connecticut. She and her husband Damian reside in Arnold, where they enjoy boating on the Chesapeake and biking on local trails. They are especially grateful with the recent addition of their first grandchild, Luna. Shannon is a Saint Alphonsus Rodriguez Catholic church parishioner and is a key contributor at the Advent Breakfast, Lasagna Dinner, August Festival and Paschal Meal.


Shannon went spelunking in search of stalactites in Custer State Park, a wildlife reserve in the Black Hills of South Dakota. She only needed to do that once.
