Get to know me

As a First Citizens commercial banker, it’s important to invest in understanding your business, strategies and key objectives. An established process and skilled team of specialists help me tailor solutions to fit you and your organization. Clients appreciate our trusted partnership in planning for long-term success.

I earned my Master's Degree from University of Phoenix and Bachelors degree from California State University Fullerton with a concentration in Finance and Business management. My career includes over 25 years in banking with the majority of that time spent in the Commercial Banking space. My specific focus has been working with clients in the Industrial, Distribution, Transportation and Medical space that are in the growth phase of the business cycle.

My spouse, Diana, and I have been married for 25 years. We are the proud parents of a son with a successful career in the Silicon Valley and a daughter who is a competitive swimmer and will be attending UC Santa Cruz for her undergraduate degree.

I am passionate about socializing with people in general, sharing stories and having a good time. Most of our weekends are filled (prior to COVID) going to dinner, concerts, events and visits with good friends and family. I sit on the executive board of the Whittier Boys and Girls club as their Treasurer and take pride in being part of a great organization that is making a difference in the lives of the youth within the community. I have been a soccer coach for several of my daughter's teams and have been the president of a dads and daughter organization called the Adventure Princess Club of Whittier, where I have made my life long friends.

I invite you to connect with me on LinkedIn.
