Norwalk, California · Fee-only fiduciary

Fee-only investing and retirement planning, from $0.

Aduna Capital is a fee-only fiduciary investment adviser in Norwalk, California, serving individuals, families and business owners across Los Angeles and Orange County — investment accounts from $0, retirement planning, and the retirement plans California now requires employers to offer.

For individuals

A 401(k) from a job you left, an IRA you opened once, a paycheck that could do more — and no one looking at the whole picture, because the firms that would want $250,000 first. We open accounts at $0, manage the money for a disclosed fee, and help with the decisions that only come up a few times: the rollover, the Roth conversion, the day you claim Social Security.

For families

Two incomes, a mortgage, children, a pension on one side and a 403(b) on the other — and advice written for one salary and one 401(k). We plan around the household you actually have: CalPERS or CalSTRS if one of you is in it, self-employment income if one of you has it, the first-generation questions no brochure covers. In English or Spanish, whichever is easier.

For business owners

California now requires every employer with one or more employees to offer a retirement plan, and the deadline has passed. We compare CalSavers against a plan of your own on your real headcount, set up the right one, and can serve as its investment fiduciary so you are not. Your own retirement — as an owner, an S-corp or a sole proprietor — gets planned alongside it.

Can we work with you?

Worth knowing before you spend fifteen minutes on a call. Most advisers bury this.

  • You live in California. That is where Aduna Capital is registered, and it is who this site is for. a principal office in Norwalk; we meet there, at your business, or on a call.
  • Any amount, including none yet. No account minimum. $50 a month after that. A household starting from zero gets the same adviser as one that isn’t.
  • English or Spanish. Natively, in either — not a translated brochure and not a different person for the Spanish call.
  • You want to keep managing it yourself. Then use the calculators, take what is useful, and never call us. They are free and there is no sign-up.
  • You live outside California — ask, and we will check. We are registered in California. Most states let an adviser with no office there take on a small number of clients without registering, and we work inside those limits deliberately — but the rules differ state by state and a couple are stricter than the rest. Tell us where you live and you will get a straight yes or no before you spend any more time on it.
  • You want someone to beat the market. We do not sell that, because nobody can reliably deliver it. If that is what you are shopping for, we are the wrong firm and we would rather say so now.

What you do changes what your money needs

Most advice is written for someone with a salary, a 401(k) and a steady month. If that is not you, the standard advice quietly does not apply. We publish a guide for each of seventeen kinds of work — what is financially different about it, and what we do about that.

The firm

Why Aduna Capital exists, and what fee-only fiduciary actually means in practice.

Founded in Norwalk in 2021 · more than sixty years of combined experience in financial services · an MBA or higher held by every member of the team · the markets followed, and the data read, every day.

Common questions

What does fee-only mean?

We are paid only by our clients, as a percentage of the assets we manage, disclosed in writing before you engage. No commissions, no product fees, nothing from a fund company or an insurer. The full schedule is published.

Is there a minimum?

No. Accounts open at $0 and we ask for $50 a month after that. Most firms that call themselves wealth managers start at $250,000; here is why we don't.

Do you handle CalSavers, or are you CalSavers?

Neither is quite right. CalSavers is the state's program; we are an independent adviser that is not affiliated with it. We help California employers decide between CalSavers and a plan of their own, and if a plan is the answer we set it up and run it. Start here.

Who is Aduna Capital registered with?

The California Department of Financial Protection and Innovation, CRD #311270. You can read our record at adviserinfo.sec.gov and our Form ADV here.
