At Rainier Homes, we’re a dedicated family-run business with deep roots in the construction industry.

Mark Smith

Austin Smith

Owner & General Contractor

With over 40 years of experience in home construction, Mark Smith is a seasoned general contractor with a deep passion for building. Growing up alongside his grandfather, Charles Rainier, Mark learned the craft of constructing homes at a young age. This early foundation instilled in him a meticulous attention to detail that remains the cornerstone of every project he undertakes today.

Mark’s commitment to quality craftsmanship is matched only by his dedication to hard work, lessons he cultivated while playing football on a full scholarship at the University of Miami. There, he earned his business degree, later pursuing an MBA from Florida Tech to further refine his leadership and management skills.

When he’s not overseeing projects, Mark enjoys outdoor activities such as jogging on the beach, golfing, boating, and fishing. He cherishes time spent with his wife, children, and grandchildren, appreciating the balance between family and professional life.

Mark’s wealth of experience, work ethic, and passion for building make him a trusted figure in the industry, always focused on creating homes that stand the test of time.

Project Manager | Craftsmanship Expert

With over 10 years of experience as a project manager, I’ve been part of the construction world since I was a child. Growing up around construction sites, I developed a strong foundation in craftsmanship and a keen eye for detail, which I bring to every project. I take great pride in delivering projects on time, within budget, and to the highest quality standards.

I hold a Business Management degree from Lynn University, where I had the honor of playing baseball on a full scholarship. This experience not only shaped my work ethic but also taught me the importance of teamwork and leadership—qualities I carry with me into every professional endeavor.

Outside of work, I’m a proud husband and father, living in Orlando with my wife and son. Our growing family loves spending time outdoors, whether it’s hiking, camping, boating, or enjoying a day at the beach. I’m passionate about balancing a fulfilling career with quality time with my loved ones.

Kevin Smathers

We waited for years to have our dream home built. We chose Rainier Custom Homes because of their upfront and straight forward business approach and overall professionalism. We were not disappointed! Mark and his team finished our home on time and better yet within our budget. Thanks guys!

Lauren R.

As a single mom I appreciated the way that Mark walked me through the building process. It made everything a lot less scary for me. He always addressed my questions directly and built a gorgeous home for my family.

Frank Mears

After interviewing and getting bids from several custom home builders, we found that Rainier Custom Homes offered a higher level of personal service and attention to detail offering a superior product that was very close to our budget. I would recommend them to anyone wanting to build a new home.

David Liput

Mark Smith and Rainier Construction were excellent to work with. Having worked with other general contractors, we had our concern. Rainier never missed one inspection and kept the work site neat and orderly throughout the entire project.
