Pinnacle Investment Advisors

Pinnacle Investment Advisors operates from Ann Arbor and Troy, Michigan, as a registered investment advisor with a distinct dual qualification: all of its managers are CPAs. The firm positions itself at the intersection of investment management and tax-sensitive financial planning, offering retirement strategies, insurance recommendations, and guidance on gift and estate tax, trusts, and mortgage issues. Its core clientele are individuals and families in Michigan and Florida, the two states where the firm is registered to do business. The firm's investment management services are delivered alongside tax and estate planning advice — a bundled offering that departs from a pure asset-gathering model. Pinnacle emphasizes a personalized approach, stating that it listens to a client's full financial picture before making any recommendations. The firm does not publicize its assets under management, underlying portfolio holdings, or a dedicated investment committee roster. Client assets are custodied at Schwab, with Millennium Trust servicing alternative holdings. Client-facing technology includes MoneyGuidePro for planning and Morningstar Portal for investment research. Pinnacle lists two office locations, serving southeastern Michigan from Ann Arbor and metro Detroit from Troy. Contact on the firm's website is directed to Brian Mulvihill. The firm has no known affiliated vehicles, philanthropic foundations, or external investment partnerships. No recent operational events were publicly documented in the last 24 months. Structurally, the CPA-led advisory model differentiates Pinnacle from most RIAs, which typically house tax expertise in an adjacent firm. Every manager's accounting credential implies that portfolio decisions are evaluated through a tax-efficiency filter — an architecture more commonly associated with high-net-worth family offices than with a Main Street advisory practice.

Frequently asked questions

Who runs investment decisions at Pinnacle Investment Advisors?

Investment decisions are made by the firm's managers, all of whom are CPAs. The firm's website directs inquiries to Brian Mulvihill, who appears to serve as the primary contact and advisor. No separate chief investment officer or investment committee is publicly identified.

How does Pinnacle Investment Advisors source its clients?

The firm holds itself out as a local, relationship-based advisory practice serving individuals and families in Michigan and Florida. It does not market through institutional channels, and its website emphasizes personalized service, trust, and the CPA credential as a mark of professionalism and confidentiality.

Is Pinnacle Investment Advisors structured as a family office or a traditional RIA?

It is a traditional registered investment advisor, not a family office. The firm is registered in Michigan, with a secondary registration in Florida. It serves multiple unrelated clients and does not report managing the capital of a single family or discrete wealth origin.

How are client assets custodied at Pinnacle Investment Advisors?

Client assets are held at Charles Schwab, as indicated by the Schwab Login on the firm's site. Millennium Trust is used for alternative asset custody, and Morningstar Portal provides investment analytics. This custodian arrangement is standard for independent RIAs and provides an additional layer of client asset protection.

What investment services does Pinnacle Investment Advisors offer?

The firm specializes in investment management, retirement planning, and insurance recommendations. It also advises on income tax, gift and estate tax, trusts, and mortgage issues. The bundled service model — tax planning delivered by the same CPA managing the portfolio — is the firm's primary structural feature.
