Today, the entire Rallis Construction team is mourning the loss of one of our incredible subcontractors and, more importantly, a great friend — Randy Postma with Postma Excavation.

Randy was truly one of a kind. He always went above and beyond for us, and we know we weren’t the only contractor fortunate enough to experience that. If Randy was on your job, you knew it was going to be done right.

Postma Excavation is truly the definition of a FAMILY-run operation. Randy, along with his boys Ryan, Eric, and Jesse, have played a huge role in helping Rallis Construction do what we do. Over the years, they have been far more than just a subcontractor to us.

We’re honestly at a loss for words.

RP, you will forever be missed by the entire Rallis Construction team. But knowing the values, work ethic, pride, and knowledge you instilled in your boys, we have no doubt they will continue to make you proud and carry on what you built.

Thank you for everything you did for us, everything you taught us, and for always going the extra mile.

Rest easy, RP. You will be greatly missed.

This was such a special project from start to finish, and we’re incredibly proud of how everything came together. From the home itself to the outdoor living spaces and pool, every detail turned out beautifully.

More importantly, we were honored to have the opportunity to build this home for some truly amazing people. We’re grateful they trusted Rallis Construction to build their home.

A beautiful home, an incredible setting, and even better people — projects like this are what make what we do so rewarding.
