What Frank Cantelmi Mechanical Engr does

Cantelmi Engineering, Inc. (operating as Frank Cantelmi Mechanical Engr) is a privately held Mechanical, Electrical, and Plumbing (MEP) consulting firm founded in 1983 and headquartered at 2130 F Street, Bakersfield, California. The firm delivers comprehensive MEP design and consultation services to architects, contractors, and builders, with a particular emphasis on California-specific regulatory compliance—including Title 24, ComCheck, ResCheck, and the specialized code regimes administered by DSA (Division of the State Architect), OSHPD/HCAI (healthcare facilities), and HCD (residential housing). Core technical capabilities include energy modeling with hourly analysis in support of code compliance.

The firm operates across five vertical segments: institutional (prisons, schools, hospitals, clinics, nursing homes), residential (low- and high-rise multifamily), hospitality (hotels, resorts, theme parks), government and military, and industrial (oil/gas, food processing, agriculture). Its service geography spans 12 U.S. states (California, Nevada, Arizona, Oregon, Washington, Idaho, Wyoming, New Mexico, Ohio, North Carolina, Hawaii) and three international markets (Jordan, Qatar, Yemen). The leadership team consists of Frank Cantelmi, PE (Mechanical Engineering) and Karen Martinez, PE (Electrical Engineering), who delivers in-house electrical engineering through her separate firm, Antrox Engineering, under a formal partnership.

The business model is professional services fee-based consulting, with engagements priced per project rather than through disclosed productized pricing. Marketing and client acquisition rely on direct relationships and reputation rather than a scaled demand-generation motion. No public revenue, headcount, or financial metrics are disclosed; the firm is independently owned with no parent company, no external funding, and no M&A activity in the available record.

Direct peers

• Interface Engineering: Portland-based MEP engineering and energy services consulting firm of comparable size and structure. Highly comparable because it offers full mechanical, electrical, and plumbing design across institutional, healthcare, hospitality, and higher-education clients with a similar regional, founder-led profile.
• Syska Hennessy Group: National MEP and critical-systems engineering firm serving healthcare, institutional, aviation, and commercial clients. Comparable as a direct competitor for MEP consulting scopes, particularly in California healthcare (OSHPD) and institutional work.
• CMTA: Engineering firm specializing in MEP design with a strong energy-efficiency and Title 24-equivalent compliance practice across institutional and commercial projects. Comparable because of overlapping MEP + energy modeling capabilities and similar project-type mix.
• ME Engineers: Specialist MEP and building systems consulting firm serving cultural, sports, hospitality, and institutional projects. Comparable to Cantelmi in core MEP design services, though operating at a larger scale across more US offices.
• Environmental Systems Design (ESD): International MEP, technology, and sustainability engineering consultancy serving healthcare, higher education, and mission-critical clients. Comparable as a peer competing for institutional and healthcare MEP scopes, though at significantly larger scale.
• PAE Engineers: West Coast-focused MEP consulting firm serving commercial, institutional, and healthcare clients. Comparable as a similarly sized regional peer with strong California institutional and code-compliance expertise that competes directly for the same project pipeline.
• Taylor Engineering: Specialized MEP consulting firm focused on healthcare, institutional, and higher-education facilities. Comparable as a similarly positioned regional peer competing for OSHPD/HCAI healthcare and DSA school MEP scopes in California.

Broad incumbents

• Arup: Global engineering consultancy with a substantial MEP and building systems practice spanning institutional, healthcare, and infrastructure. Comparable as a broader incumbent that competes for California institutional work and energy modeling engagements, though at much larger scale and broader scope.
• WSP MEP / Built Ecology Practice: Global engineering consultancy with MEP, sustainability, and energy services across healthcare, education, and government facilities. Comparable as a broad incumbent that competes for institutional MEP scopes where Cantelmi also operates, particularly in California.

Others

• Antrox Engineering: Karen Martinez's separate electrical engineering firm providing in-house EE services to Cantelmi. Comparable as a tightly integrated enabling partner that delivers the electrical leg of Cantelmi's MEP offering and shares institutional client relationships.
