John Brock has been a custom home builder/designer for 30 years since graduating from Va Tech with a BS in Civil Engineering, and an avid 20 Club member for the last decade. John has spent the last 15 years pursuing all things related to 3D modeling (models, renderings, animations, virtual tours) of all of his houses before they were built, constantly learning new technologies and advancing in the field. Along the way, he developed an estimating extension for SketchUp and started a consulting company to assist other builders by virtually building their projects before they do to help them save money and time. He has authored a book "SketchUp for Builders" with Wiley Publishing, which will be available Winter 2018. John is proud to have raised two sons who are both Army officers and serving their country.
