Born in Newark, NJ, she was a Langhorne resident for over 39 years.
She attended Montclair State University, and was employed most recently at Pennswood Village as a Sales and Marketing Counselor.
Mariann was a proud founding member of the Langhorne Literary Society ("Book Club"). She was an avid fitness enthusiast and a 35+ years member of the Newtown Athletic Club. An ideal day for her was a day at the beach and a night at a concert. She was the first one to the bar and the last one off of the dance floor.
Mariann was an avid reader and shopper. She loved good food, and was a fantastic cook. Above all, she loved fashion, family, and friends. The only was to get her away from a good sale was to spend time with her grandkids.
