About Us

Our founder Gregory Arbuckle is a licensed mechanical engineer. After obtaining his bachelor’s degree he worked for the City of Los Angeles Department of Building and Safety Mechanical Plan Check Division for 7 years. He served as a plan check supervisor for the last 3 years of his tenure. During his tenure with the Department he observed many frustrated homeowners, landlords, architects and contractors struggling to navigate the complex plan check process and not many places to turn for assistance. Here at GPM Design Engineering we understand how difficult and frustrating it can be to get your plans approved. That is why we use our knowledge and experience to guide you through the plan check process and get your plans approved.
