Leslie Mallman MBA, CFP®

Advisor San Francisco, CA

For CEOs & Business Leaders Meet Leslie

We know what it costs to lead.

Most of my clients come to me at a turning point — a new job, a growing family, an inheritance, a divorce. What they have in common is that money has gotten complicated and they want someone who will actually listen. My practice is built around the whole picture. Not just the portfolio, but the relationships, the goals, and the version of life they're working toward. That's where the real planning happens.

Your compensation is an asset.

Most advisors treat it like income.

Executive Compensation Planning

Understand the full value of your compensation package and build a strategy around base, bonus, equity, and benefits working together.

Equity & Stock Option Strategy

Navigate the timing, tax implications, and concentration risk of your equity so you're making informed decisions before the window closes.

Deferred Compensation

Evaluate your deferred comp plan within the context of your full financial picture, including timing, tax exposure, and distribution strategy.

Executive Tax Strategy

Coordinate across compensation, equity events, deferred income, and business interests to reduce your overall tax burden — not just this year, but across your career and into retirement.

Leadership transitions are personal, not just professional.

Plan for both.

Business Succession Planning

Whether you're passing the business on or stepping away entirely, build a plan that protects your legacy and your next chapter.

Concentrated Position Management

Reduce risk in a single stock or asset without triggering unnecessary taxes — on your timeline and aligned with your goals.

Liquidity Event Planning

Prepare for the financial complexity that comes before, during, and after a major liquidity event so you're making decisions with a clear plan in place.

Risk Management

Review liability exposures, key person coverage, and personal insurance so your financial life is protected.

Plan for retirement now.

Have fun along the way.

Retirement Income Planning

Design a sustainable withdrawal strategy that supports your lifestyle and adapts to markets and taxes.

Portfolio Management

Manage a diversified portfolio with ongoing rebalancing, monitoring, and risk controls.

Charitable Giving & Gifting Strategy

Build a giving plan that aligns with your values, reduces your taxable estate, and makes an impact on your terms.

Business Owner Estate Planning

Structure the transfer of business interests, coordinate buy-sell agreements, and align your personal estate with your company's future so wealth moves on your terms.

Working with Five Oceans Advisors has been game changing for my family and me. As an entrepreneur & founder, I rely on coaches and mentors to guide me. Working with Chris and his team, I’ve received incredible guidance on investment strategy, spending buckets, legacy planning, and so much more. It’s been almost 10 years since we started working together and I’m excited for the next decades continuing the journey. My family and I are leagues ahead of when we started financially and are gearing toward financial freedom. Thank you Five Oceans for all that you do.”

Meet Leslie

Originally from Chicago, I made my way to California to pursue my education in economics at Pomona College, where I discovered my love for the Bay Area. Now, having called San Francisco home for over a decade, I’ve immersed myself in its vibrant culture and community.

My career in financial advising began at a boutique investment management firm in Chicago in 2004 and has since taken several different forms, including attending the University of Chicago Booth School of Business for my MBA, starting my own solo financial advising practice, launching and growing a startup focused on accessible financial planning, and investing in private companies focused on making a positive impact in the world.

Most recently, I have enjoyed combining my expertise in financial advising with over a decade of personal healing work to create a platform for what I term ‘financial healing,’ helping individuals navigate the emotional complexities of money.

After reconnecting with Chris, whom I first met in 2014, joining Five Oceans felt like a natural fit, given our shared perspectives on the financial advising industry and desire to help clients live their best lives across all of their personal five oceans.

Outside of work, I enjoy cold swims in the San Francisco Bay, spending time in nature, and volunteering to support women’s empowerment initiatives. Daily meditation and occasional cacao ceremonies keep me grounded, while my annual trip to Burning Man offers a unique opportunity for self-expression and connection.
