Jess King – Inside Sales

Jess joined the F.R. Mahony Inside Sales team in July 2010. We call her Jess around here, not to be confused with the other woman named “Jeff”. She brings with her a Child Care education and also a Veterinary background. Those skills do, surprisingly, come in handy from time to time here at F.R. Mahony. Halloween is her favorite holiday, so if you come into our office and find one person in costume, you’ve found Jess.

When she’s not working, she spends her time lifting things up and putting them down, paying organizations and charities to run 3 miles, taking care of her hairless cat ‘Peetri’, and she also likes to believe she’s still crafty and attempts many DIY projects at home.

Jess is always on the go and continuously waiting for the next adventure.

Mahony & Associates.   He holds a B.S. in Chemical Engineering from THE University of Rhode Island.  Mike has a number of years’ experience in high rate water and wastewater process treatment systems.
