Leadership Team | Apex General Contracting

Jim Stringham

Founder & Brand President

Jim Stringham has built a reputation for standing out and moving “full speed ahead,” turning that drive into remarkable success as founder and brand president. With more than 25 years in the industry, he has grown Apex General Contracting into one of the nation’s fastest-growing exterior restoration companies, completing hundreds of millions of dollars in business and restoring more than 20,000 buildings since 2006. Under his leadership, Apex has earned recognition as a Top 100 Roofing Company in the U.S., as well as elite distinctions including Owens Corning Platinum Roofing Contractor and GAF Master Elite Contractor status. Jim’s expertise is further reflected in advanced certifications, including HAAG Engineering credentials in residential and commercial properties, and in his work as owner of Berkland Development, where he applies his construction knowledge to real estate management and development across the Midwest. Beyond business, Jim is deeply committed to his community, supporting youth sports, veterans’ organizations, and local charities. He and his wife, Bridget, owner of BeBella Hair Salon, are proud parents of Landen and Berkley, and together balance entrepreneurship with an active family life centered around their children’s many activities.

Brandon Rhymer

General Manager

Brandon Rhymer has been a key part of the Apex team since 2007, building a strong reputation through consistent top performance, a loyal base of satisfied customers, and a steady progression into leadership. After excelling for years as a top salesperson, he stepped into management roles where he helped oversee projects from start to finish, ensuring customers received exactly what they were promised while also helping hire and train new team members. Over the years, Brandon has continued to take on greater responsibility, embracing the Apex standard and helping drive the business forward with a focus on smooth, effective, and efficient operations. Now serving as General Manager, he works closely with the team to keep the company running at a high level every day. Outside of work, Brandon enjoys cheering on the Bears and Cubs, grilling for family and friends, hunting, and spending time outdoors. Above all, he treasures time with his daughter, Brynlee, whose competitive cheer and softball pursuits keep him proudly engaged in family life.

Jennifer Williams

Office Manager

Apex General Contracting welcomed Jennifer in October 2021, and she has demonstrated exceptional capabilities while successfully navigating every challenge presented to her. Before joining Apex, Jennifer spent nearly 18 years with her previous employer, and her dedication and strong work ethic make her a valuable asset to the team. Outside the office, she enjoys spending time with her husband, Matt, and their daughters, Grace and Stella. Although free time can be hard to find, Jennifer and her family still make time for trips, school events, sporting events, and concerts together. In quieter moments, she finds solace at the camper or hunting whitetail deer.

Michael Thelen

Regional Sales Manager

Michael has been with Apex General Contracting for over a decade, beginning his career with the company in June 2013. During his first four years, he was a highly awarded top performer in sales before accepting the opportunity to advance within the organization. Over the past eight seasons as Regional Sales Manager, Michael has worked closely with his sales team and their customers to build strong relationships while guiding them through a smooth sales process. With more than 25 years in the construction industry, Michael has developed extensive knowledge through hands-on field experience, along with more than 10 years in sales helping others make the right choices. Outside of work, he stays busy with his fiancée and six children. When time allows, he enjoys fishing, hunting, and nearly any outdoor activity. In his key role at Apex General Contracting, he is proud to be part of a strategic team working together to take the company to the next level in an ever-changing industry.

Joesph Metz

Sales Manager

Joe began his career in Winnebago County working for his father’s business, where early exposure to the trades helped spark a lasting passion for exterior residential construction. Today, he is a devoted father of three daughters and one son, balancing family life, sports, activities, and the demands of seeing job sites through to completion. He started his professional career as a canvasser before advancing into a field supervisor role, where his passion for exterior remodeling truly took hold through helping property owners transform their homes into places they could take pride in. Over the course of his career, he has hired and trained more than 100 people, teaching them the fundamentals of insurance restoration, building products, installation practices, and product warranties. In addition to his field experience as a contractor, his work as an insurance adjuster, where he wrote more than 1,200 storm damage estimates, gave him valuable insight into the insurance restoration process. His experience has made it clear how difficult it can be for homeowners to find a quality, integrity-based contractor they can trust, which is why Apex General Contracting takes pride in providing detailed on-site estimates, working efficiently, and never cutting corners on labor or materials to meet and often exceed local building codes while delivering high-quality results.

Austin Galvan

Production Manager

Austin Galvan joined Apex General Contracting in 2020 after graduating from Illinois State University with a bachelor’s degree. He began his career at Apex as a field supervisor working in sales, where his strong customer service skills and ability to apply what he learned in college helped him excel immediately. After four years in the field, Austin transitioned into a primarily office-based role as Production Manager, where he quickly stepped up to oversee scheduling for all builds and help ensure jobs are completed in a timely manner. He looks forward to continuing his growth at Apex and expanding his knowledge in the restoration industry. Outside of work, Austin enjoys spending time with his family, attending sporting events, and going on vacations.

Dorian Nordheim

Lead Service Technician

Dorian Nordheim brings a strong dedication to quality to the Apex team, backed by more than 25 years of experience in the home remodeling industry and a commitment to delivering customer satisfaction through a job well done. Outside of work, he enjoys a variety of outdoor activities, including hiking, trail riding, longboarding on bike paths, spending time with his children, and hitting the open road on his motorcycle. He also enjoys working with his hands through furniture building, woodworking projects, and carvings, a creative passion influenced by his late mother, whose more than 20 years as a professional clown helped instill the values and creativity that he and his three brothers carry today.
