    Dylan White

    Site Superintendent

    Dylan has a built in nature to love the outdoors, so being able to work outside and constantly be in nature is right up his alley. He also wanted to find a small company with a strong family vibe to it, instead of getting stuck in a corporate machine cranking out cookie cutter houses.

    “Tree Top Builders feels more like a family than a job,” he says. He also is passionate about learning new skills, such as climbing. He really took a liking to learning the ropes, so to speak. He has learned new climbing techniques from friends in the challenge course industry and brought them back to us to help the rest of us work more efficiently when high in the air.

    Brian Sellers

    Treehouse Builder

    Brian Sellers joined our crew after gaining some trade school experience in carpentry. He started with the basics and has worked his way up to being able to contribute to all phases of our building process. One of his favorite tasks is building railings, and he likes to think of himself as the railing guy.

    One time he was digging a hole super deep and couldn’t clean it out, so he jumped in and realized the hole was deeper than he was tall! He got covered with a dust cloud but still had a big characteristic smile on his face that we’ll never forget.
