ProClean Supply

Meet The Summerfields

James - CEO

James has been in the building maintenance and sanitation field since 1963. He founded Modesto Janitorial Supply, now ProClean Supply, in 1978. With his strong background in the janitorial industry, he has the knowledge and expertise to help customers overcome building maintenance issues. James acts as an advisor to the company’s outside consulting team, assisting them in providing solutions to customers’ challenges. One of his success stories is about an educational facility that had 20 years of coffee stains in the carpet. Over the years, the school maintenance people made numerous attempts to remove the stains but were unsuccessful. “We removed them in a few minutes and they never came back,” he recalls. A North Dakota farm boy, James has lived in Modesto since 1971. He enjoys teaching the Bible and helping people deal with their challenges.



Joel learned the janitorial supply business from the ground up. “I’ve always had a role here,” he says. He started working for his dad’s company, then known as Modesto Janitorial Supply, during high school doing everything from working in the warehouse to helping customers, repairing vacuums and even some bookkeeping. After a stint as a software trainer, he joined the family business and today he oversees sales and marketing, customer service and IT. The variety suits him just fine – “I really enjoy having different challenges every day.” Joel especially likes to help customers solve problems, like the woman with severe allergy problems who needed a vacuum. “I sold her a Miele, and now every time I see her she thanks me,” says Joel. When he’s not helping customers solve their cleaning problems, he unwinds by listening to music, cooking, doing yoga or riding his motorcycle.



As purchasing and logistics manager for ProClean Supply, Justin is always up for the challenge of making sure “everything comes in and everything goes out.” A problem-solver, he enjoys being able to overcome any obstacle to ensure that ProClean Supply's customers always get what they need, when they need it. Justin joined the family business while in high school and learned the ropes by working in a variety of areas. With all that experience under his belt, he's well qualified for his position to oversee purchasing and warehouse operations. Born and raised in Modesto, he loves the outdoors and is an avid scuba diver, hiker and mountain biker.

A self-described people person, Lavona enjoys building relationships with customers. An inside consultant, she handles sales and solves problems by phone. “The buck usually stops on my desk,” she says. Her philosophy: do whatever it takes to make the customer happy.

A real pro in the Jan/San business, John’s been at it since 1978. He services the Fresno area and enjoys helping customers with cleaning challenges.

Fabiana Lamonte
“A sales consultant is really a problem solver,” says Fabiana who joined ProClean Supply in 2016. She specializes in Laundry and Warewash, which includes any type of facility that has a dishwasher or washing machine, she explains. When a prospective client showed her a stack of laundry with stains she did a demo using one of our laundry products and turned a prospect into a happy customer. She not only loves to make customers smile, she also loves the outdoors, dancing, art, traveling…and shoes!


Mark Souza
For Mark, the best part of his job is working with customers to evaluate their needs and making recommendations that help them achieve their goals. He also enjoys developing training programs to ensure success for their employees. In his free time, Mark restores classic cars – he’s currently working on a 1950 Buick. “It’s like restoring history,” he says.
