Your Team

staff final lr

Here at Cobblestone Homes, our team members are dedicated to the principle that if it’s important to you, it’s important to us. We live and work here too. Never before has the Great Lakes Bay Region seen a team of professionals with this level of expertise assembled under one roof.

What matters more to you, though, is the team at Cobblestone never forgets we don’t just construct buildings. Mark and Melissa Wahl commit that our team always remembers that what we’re doing is creating homes where children take first steps, families gather to celebrate and memories are made.

The process of creating your dream home starts with our New Home Consultants, Matt Sheahan and Kelly O’Brien.

Matt Sheahan
New Home Consultant
Kelly O'Brien
New Home Consultant

With over a decade of experience at Cobblestone, Matt Sheahan can explain to you everything there is to know about creating your home.  He was previously a Project Manager, where he learned the ins and outs of the building process.  Along the way, he became an expert in the many features of Cobblestone homes. He holds a degree in Business Management.

Kelly O’Brien brings more than a decade of experience selling homes to families. That means she is uniquely prepared to help you create the home you’ll love at the end of the Cobblestone process. You’ll appreciate her understanding of how to work with people, thanks to her degree in Hotel and Hospitality Management.

Next, Kelly or Matt will introduce you to one of our New Home Selection Coordinators, Jill Boggs or Jennifer Sanchez. Jill and Jennifer will help you with the next step in the process, choosing paint colors, fixtures, carpet and the other details that give your new home flair and style.

Jill Boggs has a degree in Interior Design, but she also has practical experience in crafting the style of a home through furniture and cabinets. Prior to joining Cobblestone, Jill worked as a designer and salesperson in both the cabinet and furniture industries. She can help you choose a look that fits your personality and lifestyle.

Jennifer Sanchez has a background in fashion design. She knows all about making your home look good while reflecting your family’s style. She earned a degree in Psychotherapy, so she also understands the influence your home’s design has on your family’s day-to-day activities.

Next, you will be introduced to one of our Project Managers – Brian Bills, Brian Finkbeiner, Doug Jones, Nick Pratt Trevor Grames and Matt Schauman.

Brian Bills has been in the building industry for many years, including a decade working at Cobblestone. That means there’s not much in the field of custom homebuilding that he hasn’t experienced. Brian knows the answer to your questions, whether you are in our office asking about the blueprint or standing at your construction site asking about the foundation.

Brian Finkbeiner understands the importance of customer service as well as he understands homebuilding. Before working at Cobblestone, Brian worked in the restaurant business, which is all about customer service. Brian also is intimately familiar with the entire construction process. Later, he earned a degree in Construction Management.

Doug Jones has a lifelong history of working in the building industry. Prior to joining our team, he was the go-to guy at the building center he helped manage. When builders had a problem, they went to Doug to help find the solution. He also worked for a leading window and door manufacturer. If you buy a Cobblestone home, you know Doug brings solid knowledge of building materials to your project.

Nick Pratt has two degrees, one in Construction Management and another in Business. Perhaps it’s more relevant, though, that he worked in the skilled trades industry. Nick knows homebuilding from the perspective of a skilled craftsman as well as from a project manager. Nick’s customers always praise his skills at communicating with them throughout the project.

Of course, that’s not our entire team. Most people won’t meet all of us. But every Cobblestone employee is dedicated to bringing your dream to life.

Trevor Grames was in business for himself before joining Cobblestone. That experience gives him an intimate understanding of the value of the time and money you are investing in your new home. He grew up in a family affiliated with the construction business and holds a degree in Construction Management from Central Michigan University. While at CMU, Trevor was selected from a field of about 100 students to serve as a Teaching Assistant for two consecutive years.

Matt Schauman is the 4th generation in his family to work in the building industry. He brings experience drawing home plans and knowledge of the building process. While in a job at Cobblestone Homes, Matt is working on his degree in Construction Management from Central Michigan University.

Martin Wrobel
Computer Aided Drafting Designer
Dustin Weinzierl
Director of Field Operations
Kevin Grudzinski
Director of Purchasing

Martin Wrobel, the CAD designer, puts your vision on paper, making it possible for our craftsmen to construct your home the right way the first time.  The only way to get a Martin Wrobel original design is to hire Cobblestone. Cobblestone plans are not available to other builders. Martin, a licensed builder, brings 30 years of experience in designing, residential and commercial building, estimating and project management. Martin’s experience and passion bring the highest level of quality to Cobblestone homeowners.

Dustin Weinzierl, Director of Field Operations, makes sure the building processes meet Cobblestone’s exceptional standards and provides quality assurance of the overall construction. He has a lengthy history in the construction industry. He worked his way from employee to manager of a building center over the course of 16 years. He was a carpenter for a decade. For another decade, he specialized in framing components and roof trusses. Dustin knows materials.

Kevin Grudzinski, Director of Purchasing, gives homeowners a promise for what it will cost to build and power their home. Cobblestone never gives estimates. Instead, Cobblestone commits to a final home price before building begins. They also give homeowners the promise of the home's performance rating. Kevin is the key to making that promise. After a 20-year career working in sales and management for the construction supply industry, Kevin knows materials. He earned a degree in Construction Management from Central Michigan University. Kevin is actively involved through the Great Lakes Bay Region.

Shawn Boelter
Ashley Semp
Director of Client Experience

Controller Shawn Boelter’s job is to make sure everything comes together – bank paperwork and real estate transaction details – before a family’s move-in date. She helps Cobblestone families navigate the financial details of building a home. You can rest easy at night knowing Shawn is on your team and protecting your investment.

Ashley Semp, Director of Client Experience, will be with you the day you move into your home. And she’ll still be available years later if any questions arise. We call this after-purchase service “Cobblestone Care.” Through this program, Ashley is responsible for troubleshooting any issues that come up. She handles all the important details, like reminding homeowners when it’s time to change the furnace filter. Prior to working at Cobblestone, Ashley earned a degree in business management. She also was a manager at a national restaurant franchise, so Ashley understands how to match expectations and experiences. Most of our business is referrals, and Ashley is a major reason for it.
