She’s a self-proclaimed cat person. (She loves dogs too!!) She’s the personal servant of two such felines, Kira and Dante. They are spoiled kids. Outside of work she enjoys playing video games, watching TV/movies/YouTube. Anything geeky and nerdy. She’s also a fan of the game Dungeons and Dragons.

When not at work, she enjoys long or short road trips to either the White Mountains or to Moosehead Lake with her dog “Teddy Too Tall”, a Cavalier, in tow. Teddy loves the ride and company. She also has one cat named Cassie, a very sweet kitty adopted from our Boston location 13 years ago. Jean also loves a good book (she may be a book hoarder!) sitting alongside the river or any body of water. She also loves movies & HGTV…not so much into reality TV programs.
