Quantum Financial Advisors

What Quantum Financial Advisors does

Quantum Financial Advisors, LLC is a fee-only, SEC-registered investment adviser headquartered in Manhattan Beach, California, that delivers personalized wealth management to high-net-worth and ultra-high-net-worth individuals and families. Originally founded in 2005 as Quantum Wealth Management by Darius Gagne and David DeWolf and rebranded in 2022, the firm now operates as a multi-partner advisory platform led by CEO Wende Headley, CIO Gagne (a former PIMCO financial engineer with a PhD in quantum physics from UCLA), CFO DeWolf (a CPA and former Fortune 100 CFO), and COO Scott Swanson, supported by 10 CFP® professionals and additional CFA-credentialed staff. The firm serves five defined client segments — business owners, executives, individuals in new life stages (including divorce and sudden wealth), women, and UHNW families — through a consultative, fiduciary-led model that begins with a complimentary 30-minute introductory call and is supported by an in-house content engine of articles, webinars (including recurring collaborations with Dimensional Fund Advisors), and an email newsletter.

The firm's core offering spans financial planning, customized investment management, estate plan design (anchored by its trademarked Total Tax Minimization® framework), business exit and succession planning, tax minimization strategies (Roth conversions, tax-loss harvesting, GRATs, DAFs), risk management, cash flow and budgeting, sudden wealth guidance, and concentrated stock / stock option planning. Its investment process is built on a proprietary Goal-Matching framework that aligns bond and equity allocations to essential versus discretionary spending needs, using bond ladders to immunize retirement cash flows from market volatility and interest rate shocks; the methodology is grounded in Nobel Prize-winning empirical research on the science of investing. Quantum's estate-planning intellectual property is codified under the registered Total Tax Minimization® trademark, which structures trusts to simultaneously minimize estate and capital gains taxes across multi-generational, multi-entity client situations.

Quantum generates revenue through recurring advisory fees on a fee-only basis, with specific fee schedules disclosed via Form ADV Part 2A, Part 2B, and the firm's Client Relationship Summary (CRS) upon request rather than published online. Distribution is relationship-driven: marketing is primarily educational inbound (articles, webinars, newsletter) that funnels prospects into complimentary introductory calls and onto multi-year advisory engagements, with no apps, public APIs, or direct e-commerce channel. The firm operates domestically within the United States, is privately held by its founding partners with no disclosed institutional investors or parent company, and reports more than $1B in assets under management across 350+ client families.
