How We Work

How We Work

Our reasons for becoming financial professionals are deeply personal. We repeatedly saw many friends and family struggling to find the help they needed to map out their financial future. We are confident that with our understanding of personal finance, coupled with our training as financial professionals, we can help people better prepare for the future. After years in the business, we have developed a reputation for educating individuals in an easy-to-understand manner so they can grasp personal finance and use those concepts to pursue their financial objectives. We feel a commitment to our community.

Our team approach adds perspective to all we do and provides increased benefits to our clients.

Dustin was born and raised in Fair Oaks and it was his dream since he was 16 years old to open a financial services business in his hometown.  He pursued a degree at Sonoma State University specifically to be a financial advisor and graduated in three years with a degree in Business Administration, a concentration in Finance, and a minor in Economics.  Immediately upon graduating, Dustin entered the finance world, becoming the youngest financial advisor to ever be hired at Edward Jones.  

In 2004, he knocked on over 6,000 doors in Fair Oaks to build his practice.  Then in 2010, he completed an Executive MBA program with California State University – Sacramento.  After serving his clients for almost ten years in the financial planning business, he became a CERTIFIED FINANCIAL PLANNER™ practitioner in 2013.  Fulfilling a lifelong dream, in 2015 Buck Wealth Management was founded and that year was also the year Dustin partnered with the nation’s largest Independent broker-dealer*, LPL Financial, to provide his clients with an independent approach to wealth management. 

While completing his MBA, he met his future wife, Christine.  They have a vivacious five-year-old daughter, Jocelyn and their Great Pyrenees rescue dog, Eve.  Dustin has always had a passion for giving back to his community and currently serves as an Ambassador for the Fair Oaks Chamber of Commerce, a mentor for students at Meroki High School in Fair Oaks, the co-chair and founding member of the Strategic Council at the Foundation Fighting Blindness, and a member of the Rotary Club of Fair Oaks.  In the past, Dustin has served as the 2007-2008 Honorary Mayor of Fair Oaks, multiple terms as a Fair Oaks Chamber of Commerce Board Member, volunteered for the U.S. Army as a “Center of Influence” in Sacramento, served as a Chair for the American Cancer Society’s “Relay for Life” for multiple years in Fair Oaks, and more.  In his spare time, you can find Dustin barbecuing for his friends and family or teeing off at a local golf course.
