More About Greg

Growing up on a Dairy Farm there was one thing I knew I did not want to do the rest
of my life, and that was milking cows. My three brothers and I had a hay hauling
business that serviced the neighboring farmers. I became curious and intrigued of
the different types of construction that the barns were made of, so I started asking
“why” questions to all of the neighboring farmers. This was a time before google
existed (imagine that). Traveling around Southwest Missouri, I started noticing
different design and construction details in these old hot barns. I was curious about
how they were structurally designed. The structural element was a mystery and
stirred my interest. From there it was a natural progression to a two year Building
Trades Vocational Tech program in high school. I continued my construction interest
and pursued a degree in Construction Engineering from Pittsburg State University
in Kansas. I soon joined the home-building industry in Houston and never looked
back. I have also had the opportunity to build homes in North Carolina through my
connections in Houston. I have called Austin home since 1999. Flenn Custom
Homes and Remodels has been in the Austin area for more than 22-years and has
over 40-years of experience completing hundreds of custom homes and home-
remodeling projects. Having a family gives me a better understanding of what
families need in a home. I work with clients to maximize the return on their
investment and offer decision-making help when needed. I truly enjoy the process of
helping families take their dreams and make them a reality in a home that fits their
unique lifestyle. We look at every project as truly Building Works of Heart.
“Building is my passion!” And to think, it all started in a barn.
