Julie Hoffenberg, Internal Sales Support

Having moved to the UK from the USA in 1991, for what was supposed to be a year, Julie is still here!

She has had a long and varied career in sales selling advertising and real estate and, most recently, she spent the last 20 years in the fitness industry, both owning and managing clubs. Gyms were severely affected by the pandemic and Julie felt it was no longer fun running a club as she had become a cleaner rather than a fitness coach and motivator, and decided it was time for a career change.

Though fitness and well-being are still her passion and she’s at her happiest at the gym or out for a walk or run, joining Process Parameters in a sales support role has been a great move. Julie finally has some work/life balance, is working with a lovely team and happy customers and is always learning something new which makes it interesting.

Katrina Williams, Administration Assistant

Katrina joined Process Parameters late in 2021 within an administrative role opting for a change after a 7-year sales career. Developing a passion for fitness during the pandemic, Katrina spends most of her spare time in the gym or out running which aids her with being up and down the Process Parameter stairs all day!

Karen Livingstone, Marketing Manager

Karen has had a career in marketing that has spanned over 30 years split between corporate marketing in the IT Industry and being a freelance marketing consultant. She has an excellent understanding of business operations, project management, and communication channels. Results-driven, Karen prides herself in putting strategic plans in place to achieve the goals we have set for our business growth. She is then responsible for overseeing the implementation of the individual marketing activities and reporting.
