ATIS Elevator Inspections
ATIS Elevator Inspections was established as a specialized compliance and inspection firm serving the vertical-transportation industry. The business operates at the intersection of real estate, property management, and regulatory adherence — conducting mandatory elevator and escalator inspections, code consultations, and maintenance audits across commercial and multi-family portfolios. The St. Louis headquarters anchors a decentralized field-services model that deploys certified inspectors to job sites nationally. The firm's strategy centers on recurring regulatory-compliance revenue. Service lines span standard periodic inspections, modernization consulting, and witness testing, with coverage across multiple ASME and local jurisdictional codes. Geographically, ATIS maintains inspectors in key metropolitan markets from the Midwest to the Southeast, confirmed through state licensing records and public project filings. The company's posture is asset-light — deploying credentialed inspectors rather than owning elevator maintenance contracts — which allows it to function as an independent third-party auditor for building owners, management companies, and institutional landlords. ATIS Elevator Inspections is a lean organization, with a headcount model built around field-inspector density rather than large administrative overhead. Key leadership includes CEO Michael J. Tatoian, a long-tenured operator in the inspection and compliance sector. The firm does not publicly disclose total capital deployment or assets under management, consistent with the privacy norms of family-held inspection-services businesses. There are no known adjacent philanthropic vehicles or club memberships tied to the family office structure. Structurally, ATIS is unusual among family-backed investment platforms — it operates as a true operating company, not a diversified holding entity. The Tatoian family runs a single, highly specialized services business rather than a portfolio of passive investments, making this less a family office in the allocator sense and more a permanent-hold operator of regulatory-moat real estate infrastructure.

Frequently asked questions
Is ATIS Elevator Inspections structured as a traditional family office?
No. ATIS functions as an operating company rather than a diversified investment office. The Tatoian family concentrates its capital and management attention on a single regulatory-compliance services business, which is uncommon relative to the multi-asset portfolios typical of family offices. This structure reflects a permanent-hold operating philosophy rather than an allocator posture.
What regulatory jurisdictions does ATIS cover?
ATIS maintains certified inspectors across multiple US states and metropolitan areas, though exact jurisdictional counts are not publicly consolidated. The firm's inspectors hold credentials aligned with ASME A17.1 code requirements and individual state elevator-safety boards, including Missouri, Illinois, and additional Southeastern and Midwestern jurisdictions per public licensing records.
How does ATIS generate revenue?
ATIS derives revenue from recurring mandated elevator and escalator inspections, consulting on code compliance, and modernization witness testing. The model is asset-light — the firm sends certified third-party inspectors to sites but does not own elevator-maintenance contracts, positioning it as an independent auditor for property owners and managers.
Who runs investment decisions at ATIS?
Investment decisions, to the extent they involve capital allocation for the operating business, are overseen by CEO Michael J. Tatoian and the controlling family interests. ATIS has not publicly disclosed a separate investment committee or external investment infrastructure, consistent with a closely held family operating company.
Does ATIS participate in fund commitments or direct deals outside its core business?
There is no public evidence that ATIS participates in external fund commitments, co-investments, or direct deals beyond the elevator-inspection operating entity. The firm appears to allocate capital exclusively to its own service operations and geographic expansion rather than to third-party alternative assets.
