Serenus

What Serenus does

Serenus Johnson Portables LLC is a privately held construction firm founded in 2006 by Brian and Diane Johnson, headquartered in Grand Rapids, Michigan, with a warehousing and logistics facility in Midland, Michigan. The company designs, manufactures, and deploys temporary medical facilities for US hospitals and health systems facing capacity constraints, post-disaster reconstruction, or renovation swing-space requirements. Its flagship offering is MetaSpace, a componentized modular medical-space system characterized by telescoping legs, a raised-platform foundation, lightweight aluminum/steel framing, wipeable infection-control walls, and structural ratings for wind, seismic, and snow loads. MetaSpace units can be converted to negative-pressure configuration for pandemic use and assembled on tight or uneven terrain in configurations ranging from 1,500 sqft observation units to 55,000+ sqft interim hospitals.

Manufacturing lead time is quoted at 6-8 weeks, and full hospital facilities become operational within months rather than the multi-year cycle of conventional construction. All operations are founder-led; disclosed headcount is 1-10, consistent with what appears to be a lean core team supplemented by contract manufacturing and project partners. Geographic reach spans at least 15 US states plus the US Virgin Islands, with reference projects including Penn Presbyterian Medical Center, Governor Juan F. Luis Hospital (USVI), Gulf Coast Regional Medical Center, Einstein Medical Center, University of Missouri Healthcare, and Lancaster General Hospital.

Serenus operates a direct enterprise sales model, with project-based revenue generated through sales or multi-year leases of MetaSpace structures bundled with design, site assessment, installation, and project management services. Pricing is custom and quote-based, scaled to square footage, bed count, medical equipment requirements, site conditions, and timeline. Go-to-market is concentrated: customers are acquired via a dedicated phone line (800-605-0693), website inquiry, and published case studies, without intermediary distributors. Large disaster-response engagements are executed through partnerships with infrastructure contractors such as Aptim.

Broad incumbents

• ATCO Structures & Logistics: Global provider of modular space, workforce housing, and emergency-response structures including healthcare facilities. Comparable as a modular medical space competitor with broader industrial/government footprint.
• WillScot Mobile Mini: Public leader in modular space and portable storage with national fleet. Comparable as a competitor for temporary space needs; not healthcare-specialized and offers a much broader portfolio.
• Mobile Modular (Modular Space Corporation): Large general-purpose modular building leasing company offering temporary and permanent modular structures. Comparable as a direct competitor in the modular temporary space market, though broader and not healthcare-specialized like Serenus.

Emerging players

• H.E. Butt Foundation / Strategic Response Solutions: Provider of rapidly deployable medical and emergency response facilities (e.g., mobile field hospitals). Comparable in the disaster-response and emergency medical infrastructure niche.
• Modular Building Institute members (e.g., Triumph Modular): Triumph Modular and similar member firms offer temporary and permanent modular space including healthcare-adjacent uses. Comparable as smaller regional/niche competitors in modular building leasing.

Regional players

• Mashpee Modular / prefab healthcare builders: Regional prefab/modular construction firms serving healthcare systems with temporary swing space. Comparable as regional modular healthcare builders, though typically smaller and geographically limited.

Direct peers

• Blazer Industries: Pacific Northwest modular manufacturer that has delivered commercial and institutional modular buildings including healthcare projects. Comparable as a custom modular manufacturer serving healthcare customers.
• Vanguard Modular Building Systems: Designs and installs modular buildings including custom healthcare facilities. Closest direct peer given similar business model and healthcare-vertical focus.
• RedGuard: Specialty manufacturer of blast-resistant and modular buildings with a dedicated medical/emergency-response unit. Highly comparable given overlap in mission-critical, rapid-deployment temporary structures.

Others

• Eagle Medical / disaster response medical equipment vendors: Companies supplying mobile clinics, field hospitals and disaster medical infrastructure to healthcare and government buyers. Comparable thematically as adjacent ecosystem participants in emergency medical space provision.
