Greg was 12 years old when he first found his passion. He was sitting next to his father, also in the trade, riding in their work van on the way to the lumber yard. He looked over at his dad and realized he wanted to be just like him. At the time, he saw a respected man who knew a hard day’s work and knew how to be good to people and be good at what he does. As Greg grew up in the trade, he wanted to continue the proud tradition of quality craftsmanship, building and remodeling homes to help families feel safe and comfortable. He wanted to give people quality work that they could be proud of, that would last generations, just like his father.

Greg spends most of his time on project sites, working closely with the team. He enjoys new challenges and any builds that require a lot of customization – for Greg, the more detailed the work, the better. He also takes pride in teaching his team the tradition of stick framing in the right way. Greg believes in doing things the right way, the first time, and loves to see their projects come together.

When he’s not on the job, Greg loves spending time with their children, Mason and Isabella. Greg is also a major Wisconsin sports fan – he’s a Badger, Brewer, and Packer fan all the way! When he can find free time, he likes to spend time outside.




Wendy began her administrative career as an office manager for a fire protection company. It was there that she learned everything from customer service, to brokering deals. Her natural sense of humor and attention to detail were a perfect fit for clients when she and Greg started Renz Construction in 2008. Her tenacious attitude and drive helps to keep projects on time. Wendy often visits work sites to take detailed photos of projects to keep her clients in-the-know at all times.

Wendy meets with all team members of the project, from architects to engineers to clients, to make sure all projects run smoothly and to her standards. To ensure their clients have an amazing experience, Wendy tackles all the paperwork and expediting. From researching local codes to pulling permits, Wendy is the reason projects move forward quickly! Wendy acts on behalf of all their clients, going to local municipality meetings to get all permits and paperwork approved on-time.

When Wendy isn’t in the office or at the job site, she’s usually spending time with Greg, Mason, and Bella. Wendy loves gardening, walking their dog, Chewbacca, and taking in a movie with the whole family. Just like Greg, she’s an avid Wisconsin sports fan, and they all enjoy watching games together.




Anthony joined Renz Construction in 2020 and is our acting foreman and lead carpenter. While he doesn’t live in Lake Country, he loves exploring Waukesha County. His favorite part of any job is seeing everything come together at the end, to meet the vision of our clients.

When Tony isn’t working with our crew to build and remodel beautiful luxury homes, he loves spending time with his daughter, family, and friends! He also likes to travel and go fishing whenever he gets the chance!



Kris has been in the construction industry for over eight years and joined the Renz team in 2022. Born and raised in Lake Country, Kris is incredibly familiar with our area and really enjoys getting to explore new locations for our projects. When Kris isn’t working with our team as a carpenter, he enjoys making music.



Mike is one of our professional framing and finishing carpenters and brings close to two decades of experience to our team! Mike works on framing and setting homes, and has worked on a number of our major projects, including his favorite, Pine Lake Manor. Mike is dedicated to his work as a carpenter but enjoys his time relaxing when he isn’t building with our team!


Apprentice Carpenter

Mason, Greg and Wendy’s oldest son, picked up the carpentry trade at an early age and has been working formally with Renz Construction as an apprentice. Over the last few years, Remi has been honing his skills as a carpenter and has really taken an interest in rough carpentry, building homes from the ground up.

When Remi isn’t on site working, you can catch him hanging out with his friends, usually outside when he gets the chance. He’s big into hunting and fishing – anything that gets him outdoors!


Jackson (JJ)

JJ joined the Renz team in 2023 and is building his skills as a carpentry apprentice with our incredible team. He’s been in Lake Country most his life and is eager to build new beautiful homes in our area. So far, he likes all the day-to-day tasks that come with construction carpentry and can’t wait to learn more.

JJ loves to play and watch sports of all kinds, work out, and hang out with his friends when he’s not working.
