What is Complete Family Office?
Complete Family Office is a private family office that serves as a single, trusted point of contact for high-net-worth families. It coordinates a family's wealth, legacy, and lifestyle — acting as the quarterback for the attorneys, accountants, investment managers, and other professionals in a family's life, so nothing falls through the cracks. The firm is legally Complete Family Office, PLLC, a wholly-owned subsidiary of MDS Financial, PLLC.
What is a family office, and do I need one?
A family office is a private organization that manages the financial and personal affairs of a wealthy family in one coordinated place. Families with significant wealth often work with many excellent specialists but have no one connecting them. A family office fills that gap — integrating tax, estate, investments, governance, and lifestyle so the family can focus on what matters instead of on administration.
What services does Complete Family Office provide?
Services span three integrated pillars.
Wealth, Tax & Reporting: proactive tax strategy, consolidated reporting, bill pay, entity administration, and investment oversight.
Governance & Legacy: family mission and constitution, next-generation education, philanthropy, and conflict mediation.
Lifestyle & Concierge: homestead and asset management, travel and signature experiences, health care planning, and digital and physical security. In total, twelve core services, delivered or expertly coordinated. See the
full list of services.
Who does Complete Family Office serve?
It serves high-net-worth and ultra-high-net-worth families of significant means who want one advisor to see and coordinate their entire financial and personal picture. By design, the firm takes on only a small number of families so each relationship stays personal and deeply attentive.
How is a family office different from a financial advisor or wealth manager?
A wealth manager typically focuses on investing your portfolio. Complete Family Office is broader: it coordinates every professional and decision in your financial life — tax, estate, investments, governance, and lifestyle — and charges a flat monthly retainer rather than a percentage of assets. It does not sell investment products or take custody of money; it acts as the family's independent quarterback.
Does Complete Family Office manage my investments?
No. Investment management remains with your chosen managers. Complete Family Office provides independent oversight and coordination of your portfolio and advisors, but does not take custody of assets or charge asset-based investment fees.
How much does Complete Family Office cost?
Engagements start at a flat
$5,000 per month retainer. The fee is always a flat monthly retainer, never a percentage of your assets. As a rough reference, most families can expect to pay 50–75 basis points of net worth per year. Fees do not include investment management, which stays with your chosen managers. More on our
pricing.
How does Complete Family Office keep my information private?
Discretion is the foundation of the firm. It uses encrypted systems and secure document storage, strict need-to-know access controls, and confidentiality written into every engagement. Nothing is ever shared with anyone without the family's direction.
What is the firm grounded in, and what are its credentials?
The firm is grounded in deep accounting and tax expertise. It was founded by Michael Siggins, CPA, and is a wholly-owned subsidiary of MDS Financial, PLLC, an Arizona registered CPA firm. Any tax return preparation and filing is performed by MDS Financial, PLLC; all other services are provided by Complete Family Office, PLLC.
