Our Team

Lauren Klein, CFP®, CDFA®, MBA®, EA
Founder & President

The unique combination of Lauren's professional and personal experience are what have made her a trusted advisor to many. Her deep financial roots include positions at various Fortune 200 corporations, including 16 years with Avery Dennison. She has also served as a Chief Financial Officer for multiple companies, and as a tax professional and an independent consultant. 

Lauren was widowed after being a caregiver to her husband Ed, and she is also a breast cancer survivor. These events - among many others - have impressed in her importance and value of living life fully and with meaning every day. Her purpose is to share this value with her clients. 

Lauren is a CERTIFIED FINANCIAL PLANNER™ (CFP®) Practitioner, a CERTIFIED DIVORCE FINANCIAL ANALYST™ (CDFA®), and a NAPFA Registered Financial Advisor. A member of the Financial Planning Association (FPA), she served as a board member of the Orange County chapter from 2005 to 2008. She is also an active member of the International Academy of Collaborative Professionals and Collaborative Divorce Solutions of Orange County - Practice Group. Lauren earned her bachelor's degree in accounting from Fairleigh Dickinson University, and an MBA® from Pepperdine University. To further her ability to assist with collaborative divorce services, she has also completed mediation training at Mosten Mediation.

Always committed to giving back to the community, Lauren has served in key financial and service roles on many non-profit boards. She currently serves on the Board of Directors of Heritage Pointe, on the Advisory Board of the Jewish Community Foundation of Orange County and the American Jewish Committee—a global advocacy organization. She has also served on the Executive Board of the Jewish Federation and Family Services of Orange County. Lauren lives in Irvine, California. 

Brittany Mangrum, CFP®
Associate Financial Planner

Brittany joined Klein Financial Advisors in early 2019. A CERTIFIED FINANCIAL PLANNER™ (CFP®), she has a clear passion for educating clients and helping them make smart decisions that support a lifetime of financial confidence.

Brittany’s drive to help people gain control of their financial lives is, at least in part, the result of losing her mother at just 16 years old. After spending the following months helping her father get the family’s financial affairs in order, she saw first hand the vital role of smart planning, as well as how having a comprehensive plan can boost your confidence moving forward. Ever since, she has wanted to help others take the necessary steps to build a solid financial foundation and begin planning for the future as early as possible.

Brittany’s mother’s biggest wish was that she pursue a strong education. Brittany did not let her down. She graduated from high school at age 16 and went straight to college where she earned a bachelor’s degree in finance with a minor in financial planning, as well as a master’s degree in taxation from Cal State Northridge. Her CFP designation is icing on the cake. She is also an active member of the Financial Planning Association (FPA) of Orange County.

Though she interacts with all of our clients, as a bona fide Millennial, Brittany brings a fresh, new perspective on all things financial that is particularly appreciated by our younger clients. One of her proudest accomplishments at her prior firm was educating her co-workers about their company-sponsored 401(k) plan—which they’d had access to for years but did not understand—and creating a huge wave of participation! Her passion for financial planning is infectious.

Whether Brittany’s energy comes from her 13 years as a cheerleader, her spirit as a huge sports fan, her enthusiasm for staying active (she hikes, paddleboards, and participates in high-intensity interval training, just for starters), or something else entirely, one thing is clear: Brittany loves cheering people on and encouraging success. We’re thrilled to have her on our home team!
