Mosaic Financial Group
Mosaic Financial Group was formed in 2001 in Chicago, with John Nersesian and David Lantsberger as managing directors. The firm traces its roots to a boutique wealth management practice that grew by serving executives, business owners, and multi-generational families. It is structured as an SEC-registered investment advisor, offering financial planning and asset management under a fiduciary standard. The firm's strategy centers on holistic wealth management: financial planning, investment management directed through low-cost passive and active vehicles, tax-aware portfolio construction, estate and trust planning, and family governance. Its geographic footprint appears concentrated in the Chicago metropolitan area. Public filings list no direct equity investments in operating companies; instead, Mosaic allocates client assets across ETFs, mutual funds, separate accounts, and private alternative investments sourced through select third-party managers. Mosaic's team includes financial planners, CPAs, and a small operations staff. It maintains no disclosed foundation, family office investment vehicle, or proprietary product. Recent operational milestones include 2021 SEC filings showing continued advisory growth and new hire adds, though specific dollar flows are not publicly itemized. Mosaic differentiates itself as an independent fiduciary with no affiliation to any product manufacturer. Its governance structure resembles a traditional RIA partnership rather than a single-family office, limiting its direct co-investment capability. It competes for high-net-worth clients on planning depth and tax efficiency rather than scale or proprietary deal flow.

Frequently asked questions
Who runs investment decisions at Mosaic Financial Group?
Investment decisions at Mosaic Financial Group are made by the advisory team led by Managing Directors John Nersesian and David Lantsberger. The firm uses a committee-based approach to select and monitor investment vehicles, primarily through third-party ETFs, mutual funds, and alternative manager allocations. Client portfolios are customized based on financial plans and risk profiles.
Is Mosaic Financial Group a single-family office or an independent advisory firm?
Mosaic Financial Group is an independent registered investment advisor (RIA), not a single-family office. It serves multiple unrelated families and individuals. The firm does not manage a proprietary fortune or have a single controlling family; rather, it operates as a multi-client wealth manager with fiduciary obligations to all clients.
Does Mosaic Financial Group make direct investments or co-investments?
Mosaic Financial Group does not directly invest in private companies or hold positions in operating businesses in its own name. Client portfolios may contain private alternative assets, but these are accessed through pooled vehicles, managed accounts, or registered funds offered by third-party managers. The firm reports no direct deal-making capabilities.
What investment stages and sectors does Mosaic Financial Group focus on?
Mosaic Financial Group focuses on liquid public markets for core client portfolios — equities, fixed income, and alternatives. It does not target specific venture or growth equity stages. Sector allocations are determined by broad market indices and client-specific risk parameters, not by top-down thematic bets.
Where does the underlying wealth managed by Mosaic Financial Group originate?
Mosaic's client base includes high-net-worth executives, business owners, retirees, and multi-generational families, primarily in the Chicago area. The source of wealth varies by client and includes business proceeds, corporate executive compensation, family enterprise liquidation, and inheritance. Mosaic does not disclose aggregated client wealth breakdowns.
