Started at the age of 13 on the survey crew, moved on to designing projects at the age of 16, I've spent my teenage years and entire adult life working in Land Development and Civil Engineering. As my Civil Engineering career developed, I naturally felt a pull to Land Development and along with Jeffery and Hunter, have established a desire and passion for helping clients not only meet their project goals, but accede them.
