What TerWisscha Construction does
TerWisscha Construction (TWC) is a privately held design-build construction firm founded in 1963 in Willmar, Minnesota by John TerWisscha, operating as TerWisscha Construction, Inc. The firm specializes in designing and building veterinary hospitals and clinics, pet boarding and daycare facilities, dental offices, and ambulatory surgery centers on a nationwide basis from its Minnesota headquarters and a Sunbury sales office. TWC employs more than 60 people and delivers projects through a proprietary six-step process covering preliminary planning, cost analysis, statistical study, developmental design, architectural services, and construction buildout, supported by in-house architects, consulting engineers, development consultants, and on-site superintendents, with actual construction labor provided by local subcontractors in each project market.
The company's core technology stack centers on Procore construction management software for project coordination and a client portal for subcontractors. Beyond core design-build, TWC operates a managed IT services line for veterinary clinic clients covering network setup, data security, hardware/software audits, and help desk support, and runs a specialty coatings and flooring subsidiary through animalcareflooring.com. The firm has over 250 veterinary facilities in its reference portfolio led by CEO Kelly TerWisscha and a specialized architecture team under Tim Parsons, AIA, who has designed more than 50 veterinary projects nationally.
The business model is project-based professional services revenue from custom-quoted design-build engagements, supplemented by managed IT services and coatings installation. The firm markets primarily through direct enterprise field sales with a consultative, no-obligation preliminary planning entry point, supported by industry conference presence (VMX, Fetch Central, dvm360), podcast appearances, and a referral and advisory board network. Customer segments are organized vertically — veterinary hospitals, pet hospitality, dental and oral care, and ambulatory surgery centers — with a small local Central Minnesota commercial projects segment. The company remains family-led under Kelly TerWisscha (CEO), Keith Nelson (President), Brian Heinen (COO), and Rachel Coleman (CFO), with no external institutional investors.

TerWisscha Construction competitors and assessment
Company assessmentBroad incumbents
- McCarthy Building Companies: One of the largest U.S. healthcare-specialty design-build general contractors. Comparable in vertical focus (medical/hospital construction) and integrated delivery model, but operates at substantially greater scale and geographic breadth.
- Mortenson Construction: Large privately held U.S. builder with healthcare among its verticals. Comparable in private ownership and vertically integrated model; meaningful divergence in scale and breadth of vertical focus.
- DPR Construction: Large private design-build contractor with healthcare and advanced technology focus. Comparable in integrated design-build model and disciplined customer-segment focus, but operates at materially larger scale.
- Brasfield & Gorrie: Privately held commercial general contractor with strong healthcare practice. Comparable as a privately held GC with healthcare specialization, though significantly larger and more diversified across verticals.
- JE Dunn Construction: Privately held commercial general contractor with substantial healthcare vertical. Comparable as an employee-owned private GC with healthcare construction expertise, but at far greater scale than TWC.
Direct peers
- Haskell Company: A privately held design-build firm with a longstanding healthcare and commercial vertical focus. Comparability is strong given overlapping integrated design-build delivery model and institutional/commercial healthcare customer base.
- Boldt Company: Privately held integrated design-build firm with strong healthcare and industrial vertical mix. Comparable in being a privately held, family-rooted design-build contractor with vertical specialization and integrated self-perform capability.
- Robins & Morton: Privately held general contractor with deep healthcare construction specialization. Comparable in vertical specialization and integrated design-build approach, though TWC's veterinary focus is even more narrowly niche.
Regional players
- Hoar Construction: Privately held commercial general contractor headquartered in the South with healthcare and corporate interior specialties. Comparable as a mid-sized private design-build firm with commercial/healthcare focus.
- W. M. Jordan Company: Privately held Mid-Atlantic design-build general contractor with healthcare, education, and commercial practices. Comparable as a mid-size private firm with healthcare-inclusive project mix, though smaller in veterinary specialization.
