Jesse began his career working as a draftsman in the summer of 2006. After working for three years for another company, Jesse ventured off and started his own company, KL Drafting & Design, in 2009. Jesse learned all aspects of the building permit industry throughout these years. Jesse is very familiar with the zoning and building codes of all the jurisdictions within San Diego County. Any size job, Jesse would handle, from retaining walls, decks, all the way up to custom homes and multi-family dwellings.
Through the years, the workload has expanded and has brought Jesse to where he is today. In 2022, Jesse decided to build a team to keep up on the workload and fast-track projects by keeping them in-house for as long as possible, where PRO-CAL Design kicked off.
