MKE IRON'S HOME OFFICE TEAM

RICHARD_ZIMMERMAN-HOAN-WEB.jpg

Rich Zimmerman

PROJECT MANAGER | ESTIMATING - DIVISION 3

Rich Zimmerman’s ability to expertly estimate, and manage operations comes from his diverse experiences in manufacturing, ironworking, and project management. His background equips him with the unique ability to manage project details from the ground up while still seeing the big picture. This means he is able to catch problems before they start, and he’s consistently able to provide efficiencies saving project partners time, stress and money.

Motivated by his past as an ironworker Rich says, “There are guys depending on me to be there for them. If I don’t do my job, there is no job for them.”

This is what drives him to provide the best customer service possible, and

to carry out projects in the safest way possible. Looking forward Rich believes advancements in prefabrication will drive innovation for the industry.

At home, Rich is a husband and a father of four. He also puts his management skills to good use supporting his son’s racing career as the pit’s crew chief.

Joe Speth

YARD FOREMAN

A skilled mechanic with nearly 20 years on the road Joe Speth says, “I love anything that runs on gas or diesel. I love more power.”

That passion fuels his efforts to keep MKE Iron's equipment in peak working condition allowing projects to run like a well-oiled machine. Even better, the reliability Joe brings to our team is backed up with OSHA training that reflects our commitment to safety.

Working for a flexible, family owned business that promotes work/life balance motivates Joe to provide service that makes 

our customers just as happy with MKE Iron Erectors, Inc. as he is.

So does the challenge of finding a fix for something he’s never repaired before. 

 

Married with twin daughters, Joe spends his downtime coaching

his daughters’ t-ball team, and fixing things around the house.

He also enjoys spending time with his grandparents in Northern Wisconsin and fishing.

Mark Redetzke

DIRECTOR - MARKETING | BUSINESS DEVELOPMENT

Mark Redetzke’s favorite piece of construction equipment is his Macintosh. He points out, “It’s the most versatile tool. With that little box I can research our industry and produce compelling creative messages explaining who MKE Iron Erectors, Inc. is.”

 

Mark has nearly 25 years in department store marketing, so for him switching to construction is a great growth experience. Mark states, “Retail is a great industry to learn customer service in because it’s highly competitive and it requires creating messages that engages people on a personal level. Just like relationships in construction, it all boils down to establishing trust.”

​

Mark is a husband and a father of three kids who have, as he says, “rocked my world from the moment they stepped foot into it. They teach me how to be a better person, and I couldn’t be more proud of them.” Outside of that, Mark enjoys evenings with good friends next to a bonfire and a glass of good whiskey.

Anne Runkle

PROJECT ACCOUNTANT |
ACCOUNTS PAYABLE

What gets Anne Runkle out of bed every morning? As a construction professional it’s the opportunity to take part in creating positive results. Anne states, “I love construction: watching something grow from the bottom up.” This means she’s either in the office, or in the field meeting customer needs, helping to resolve issues, and building relationships to ensure positive outcomes for each project. 

 

Even though Anne brings over 20 years of team building, and problem-solving experience to the table her resilient nature spurs her to constantly grow as a professional. She says, “If you’re not learning, you’re not growing.” This attitude extends to her ability to learn from listening to customer and team needs allowing her to stay on top of challenges as she works to keep expectations realistic. 

 

Outside of MKE Iron, Anne is a mother of three adult kids who enjoys camping, hiking, biking and cooking.
