Every strong team starts with a shared purpose, and for us, that purpose has always been people.
When Dave and Lyndsye first partnered up, it wasn't just about combining skills or expanding market reach. It was about shared values, trust, and a genuine belief that real estate can feel both personal and professional. Nearly three years later, we're proud of what we've built - a team that works hard, laughs harder, and always puts clients first.
As NW Indiana realtors with Century 21 Alliance Group, we serve Valparaiso, Crown Point, Portage, and the surrounding Northwest Indiana communities. But more than that, we're your neighbors. We live here, we invest here, and we're committed to this community for the long haul.
With 39+ years of sales experience and 20 years specializing in NW Indiana real estate, Dave brings proven expertise to every transaction.
A 1988 Valparaiso University graduate, his career began with 11 years of corporate sales and management in Downtown Chicago before transitioning to business ownership as a partner in a wholesale distribution company in Michigan City. In 2005, Dave launched his real estate career, and in early 2025, he acquired Century 21 Alliance Group, where he now serves as Broker/Owner. An award-winning Quality Service and Ruby Award recipient, Dave specializes in new home construction, buyer sales, and existing home sales, with individual and team volume exceeding $70M over the past decade. A longtime member of Calvary Church in Valparaiso, he has served as an Elder, Small Group Leader, and Head Men's Golf Coach at Valparaiso University for over 15 years. Dave has great respect for the fact that buying, selling, or building a home is deeply personal, and he would be honored to guide you through every step.

Real estate is one of the biggest decisions you'll make, and we believe the process should feel supportive, strategic, and personal. Here's what working with us looks like:
Your goals, your timeline, your concerns - they all matter. Before we make a single recommendation, we take the time to understand your unique situation and what success looks like for you.
From pricing your home to positioning it for the right buyers, every decision is backed by market data, local expertise, and a clear plan. We don't believe in one-size-fits-all approaches.
You'll never wonder where things stand. We keep you informed, answer questions promptly, and make sure you feel confident every step of the way.
Our relationship doesn't end at closing. We're here for questions down the road, referrals you might need, and the next chapter when you're ready.
We're more than NW Indiana realtors-we're community members who care deeply about the place we call home. From Valparaiso's vibrant downtown to the peaceful acreage of Union Township, Northwest Indiana offers something for everyone.
We believe asking the right questions makes all the difference. Whether you're interviewing us or another agent, here are the questions we think every seller should ask.
