Our clients have come to rely on us as trusted advisors and our commitment to fast, accurate, value-added turnaround times has set us apart from our competitors. We believe responsiveness is critically important to our clients. We are committed to minimizing your stress  and maximizing your future.

Quality

An accounting firm’s reputation is based on its quality of service. Our firm’s reputation reflects the high standards our clients demand of us.

Our primary goal as a trusted advisor is to always be available and to provide insightful advice to our clients; this allows them to make informed financial decisions. Our clients demand nothing less and we constantly strive to deliver.

With constantly evolving tax law, business best practices, and economic conditions we believe it is extremely important to constantly seek continuing education. We are committed to professional education so that we can provide the most up to date technical expertise, and poses the most relevant financial, and business acumen available to our clients.

Team Approach

We run our firm with a “Team Approach” philosophy. When Dave first started his practice he thought he could do it all; perform every type of service that an accounting firm was expected to provide. Twenty years in practice has taught him that forming a network of professionals that offer the specializations needed in this economic environment is critical to our clients success. Therefore, Del Sesto & Sterrett, LLP have learned to say, “we may not have the answer, but we know someone that does”. We call this our “Team Approach”. We have developed a team of professionals and consultants over the years that many of our clients have successfully worked with. 

Our Partners

Dave Del Sesto

I was born in 1960 in Providence, Rhode Island and at the age of four my parents moved our family to Orange County, California. My elementary school years were spent in Fullerton with the remainder of my youth in Villa Park. One of the things my father impressed upon me through high school was that I needed to have an in-depth understanding of tax law. I took his advice, became a registered tax preparer and started with preparing my friends tax returns in 1978 when I was 18-years-old. This is when I learned that preparing tax returns was something I loved to do and I haven’t stopped since.


My first year out of high school was spent in Los Angeles attending a one-year program at California Center for Biblical Studies. I then attended Cal State University, Fullerton and in June,1986 graduated earning my Bachelor’s degree in Business Administration with an emphasis in Accounting. Throughout college I worked full-time doing classic car restoration, selling life and health insurance and preparing tax returns. Following graduation, I went to work for Ernst & Whinney (now Ernst & Young) in Los Angeles and within six months found myself working in the Orange County office. I spent almost three years with the firm. I left them for a position as Property Manager at Warmington Homes for a year before I took over the current accounting practice Myles and I now have.

Dave currently resides in Tustin, CA with his wife Suzie and two daughters Mariah and Morgan.

Myles Sterrett

Myles, a Southern California native, attended Murrieta Valley High School (MVHS) and oddly enough that is where he was exposed to accounting. During his junior year at MVHS Myles took introductory business and accounting classes and gained a quick appreciation for the trade. Considering accounting as a viable career Myles decided to study Economics and Accounting at the University of California, Irvine (UCI).

While pursuing his degree at UCI Myles co-founded a chapter of the professional business fraternity Delta Sigma Pi. Myles saw membership grow from two members to over 50 in the first year. The chapter now boasts 50 plus members a year. During his junior year Myles completed an internship with Deloitte & Touche in their Business Advisory Services practice. In addition to his internship Myles continued to work part-time for Dave Del Sesto assisting in tax preparation and miscellaneous special projects.

Upon graduation from UCI he began his career at Deloitte & Touche and this is where he obtained his license to practice as a CPA in California.  At Deloitte & Touche Myles spent four years between the Business Advisory Services and Federal Tax departments. In the Federal Tax department Myles focused on high net worth individuals, partnerships, and corporate entities. After his departure from Deloitte he then spent the next year and a half working with Dave Del Sesto focusing on tax preparation/planning and business consultation.

In 2013 Myles moved out of public accounting to become controller for a private equity backed environmental company specializing in air testing and environmental laboratory services. Myles was controller through rapid growth helping double revenue over two years. Myles assisted in over 10 buy-side acquisitions; assisting in financial due diligence, operational integration, financial system design, maintaining bank covenant compliances, financial reporting, and financial audit preparation.

Myles currently resides in Murrieta, CA with his wife Elaina and two sons Remy and River.
