Our Mission

How did we get here…

Engineered Tax Services, Inc. (ETS) was founded by Julio P. Gonzalez. Julio saw the need for a company that could provide services to CPA firms, business owners, and commercial property owners to utilize specialty tax incentives previously available only to Big 4 accounting firms and Top 100 corporations. His vision encompassed a way to allow clients the utilization of tax incentives that could increase cash flow, expand service offerings, retain competitive advantage, and provide all of these consultative services under one roof.

Even better, his vision was to create a company that provided a valuable service both to its clients and their surrounding community. ETS is a professionally licensed engineering firm providing a broad range of engineering based services – from top 100 firms to small “ma-and-pop” businesses. ETS has over 100 employees dedicated to this industry. We currently complete hundreds of studies each month for firms across the country.

ETS Gives Back

Julio’s vision to support and give back to the community  includes the adoption of a local elementary school located near our ETS headquarters. We have pledged support, donations, and campaigns to help aid the school, its dedicated teachers, and the students of Roosevelt Elementary School. If you are interested in donating to the school, Julio has promised to match any donation up to $5,000. Please contact us for more information here.
