Custom Woodwork

About Us

I started buying, fixing, and flipping houses when I was 25 years old. I have since bought, renovated, and built 28 houses. I worked diligently on each project, managing my budgets to earn a profit once house sold, refining the process with each new deal. Because this is so ingrained in my life, it is not just a job. I wake up every morning and get to do what I love. Building and renovating homes is extremely rewarding and I truly enjoy the process, working with my team, the homeowners, designers, and architects.
