Cornerstone Family Office

Sean Barrett


Dana Point, CA


Cornerstone Wealth Advisors, Inc. (CWA) is a Registered Investment Advisory Firm providing wealth management services to affluent families, professionals, business owners, executives and retirees who need a game plan for the second half of their lives and a coach to help them navigate the pitfalls of retirement. We provide our services within an independent family office setting by offering comprehensive, integrated wealth management including budgeting, bookkeeping, tax prep and business consulting services through our sister company, Barrett Solutions. Therefore, we can orchestrate for affluent clients a broader range of financial services than most firms due to the scope of our core competencies.

We are fee-based advisors. This allows us to be product neutral when recommending a strategy or solution to our clients, thus acting with a true fiduciary perspective. The exception to this rule involves complex wealth management strategies for our more affluent clients, which may include insurance solutions that are offered through our broker dealer relationship and are by design, commission-based solutions. In these instances, we will always provide multiple options to the client and complete fee disclosure to the client, along with any fee-based alternatives, if available.

Sean Barrett, CEO & Founder
MBA, CFS Senior Wealth Strategist

Sean has over 20 years of experience as an international, corporate and private banker working with senior executives of companies across the U.S., primarily in Southern California. He left Citibank’s Private Bank 15 years ago, where he managed relationships of high net worth clients, to build a wealth management practice in San Diego within the wire house segment eventually migrating from Merrill Lynch to Smith Barney to Morgan Stanley.

In 2010 Sean left Morgan Stanley-Smith Barney to form Cornerstone Wealth Advisors, Inc. a Registered Investment Advisory firm headquartered in Carlsbad California. In 2014 he stepped down from Cornerstone Wealth Advisors to establish Cornerstone Family Office. He now focuses his efforts on affluent families, helping them simplify their lives by managing the multitude of professionals they have reporting to them, which allows the principals to get on with the second half of their lives and eliminate the day to day administration of the family business interests.

Sean is a graduate of St. Benedicts College with a BA with honors in economics and an MBA in finance from Indiana University. He has completed the CFP Professional Education Program and is a Certified Senior Advisor. Sean is also a Qualified Kingdom Advisor. He is married to Denise, who is a Quick Books Professional trainer who has managed her own book-keeping, training and small business consulting business, Barrett Solutions Inc., since 1980. They have four children and five grandchildren and recently became great-grandparents to a baby girl. Whatever time Sean has after family demands is spent golfing, traveling, walks on the beach, riding his bike, and watching USC football.
