What We Do

One discipline. One trusted partner.

We acquire and grow fragmented, recurring-revenue field service businesses: the essential, often compliance-driven work that keeps facilities, equipment, and infrastructure operating. We hold for the long term and build around the teams already doing the work.

Recurring Service & Maintenance

Scheduled, contract-driven work that customers cannot defer: inspection, servicing, preventive maintenance, and the routine visits that keep equipment and facilities running day after day.

Contract Density

Compliance & Safety

Regulated, audit-driven services where certification, documentation, and code adherence are non-negotiable. The work gets done because it has to, not because the economy is strong.

Audit-Ready

Repair & Response

Skilled field technicians dispatched when something breaks or falls out of spec. Fast, reliable response and deep customer relationships that competitors cannot easily replicate.

Field-Proven

Specialized Field Operations

Route-based, technician-led businesses serving commercial and institutional customers, built on tenure, trust, and the operational know-how that only comes from years in the field.

Route-Based

Our Process

Straightforward from first call to close.

First Conversation

We listen first. We want to understand your business, your team, and what a good outcome looks like before we talk about numbers.

Letter of Intent

If there is alignment, we move to a non-binding LOI within two weeks. Key terms laid out clearly, with no ambiguity and no surprises.

Confirmatory Diligence

We conduct focused, respectful diligence. We confirm what you have shared. This is not adversarial. It is a collaboration.

Close & Transition

Typically 60 to 90 days from LOI. We handle the complexity. You focus on your business until the day it transfers.

Where We Invest

We focus on industries that share the same shape.

We are not confined to a single vertical. Instead, we focus on essential field service industries that share a common set of characteristics, the traits that make a business durable, defensible, and worth holding for the long term.

Essential, non-discretionary work Recurring, contract-driven revenue Compliance and safety mandates Fragmented, owner-operated markets Resilient across the cycle Tenured, skilled technician teams

Four industries we know well

A few examples of where these characteristics come together. They are illustrative, not exhaustive, if your business shares the traits above, we would like to talk.

Healthcare Technology Management

Inspection, calibration, and repair of clinical and biomedical equipment, governed by strict regulatory and safety standards that keep the work recurring and non-negotiable.

Kitchen Exhaust Hood Cleaning

Fire-code-mandated cleaning of commercial kitchen exhaust systems, performed on required schedules for restaurants, institutions, and food service operators.

Industrial Water Treatment

Ongoing treatment, monitoring, and servicing of cooling towers, boilers, and closed-loop systems that facilities cannot allow to fall out of spec.

Medical Waste Hauling

Scheduled, regulated collection and disposal of medical and biohazardous waste, a compliance-driven service with dependable, route-based recurring demand.

For Business Owners

Thinking about selling your field service business?

If you own a field service company and you are thinking about what comes next, we want to be the first call you make. We are a dedicated acquirer, not a broker, not a marketplace, and not a financial buyer who will strip your company down. We acquire and grow.

Strong recurring or repeat revenue and long-standing customer relationships
Dependable, tenured technician teams and a reputation for reliable service
Economically resilient sectors that hold up across the cycle
An owner who cares about what happens to their team after they step back

Why Par 3

We do things differently than every other buyer.

Field service is the unseen infrastructure of the economy. When the work stops, schedules collapse, facilities go offline, and revenue evaporates. The companies that get it right are built by great technicians, great service managers, and great owners, and our job is to honor that. When you sell to Par 3, nothing that matters gets torn apart.

01 · People

Your team stays.

We do not restructure what made you successful. Your technicians, dispatchers, and account managers keep their jobs, their tenure, and their customer relationships. We build around them.

02 · Brand

Your name stays.

In almost every case, your company keeps its name. The customers you earned trust with keep working with the brand they have known for years. We operate behind the scenes.

03 · Legacy

What you built stays.

We are not buying your business to flip it. We are building a long-term home for the operators who built these industries, and we intend to hold it that way.

04 · Culture

People-first is the model.

Technician retention, response time, and customer relationships are not soft metrics. They are the business. We invest in the people who drive them.

05 · Operations

Support, not interference.

We bring professional tools: dispatch systems, back-office support, technician recruiting, and technology. We take the admin burden off your team, not the work.

06 · Process

Straightforward to close.

LOI within two weeks of alignment. Diligence and close typically within 60 to 90 days. No drama, no surprises. We move when there is conviction.

Our Values

How we show up every day.

Stewardship First

Advancing an owner's legacy is a privilege. We do right by our partners, their teams, and their customers in good times and in bad.

People Are the Business

Technician retention, response time, and customer relationships are not soft metrics. They are the moat. We invest accordingly.

Excellence Without Shortcuts

We hold ourselves to the highest standards of service quality and compliance. Trained, documented, and accountable.

Honest and Direct

We say what needs to be said. We do what we say we will do. The operators we work with deserve nothing less than that.

Long-Term Thinking

We are not buying businesses to flip them. We are building a platform we intend to hold for a decade or more. That changes everything.

Curious and Humble

We show up to learn. The operators who built these industries know things we do not. We ask questions before we make decisions.

Meet the Team

Operators, not financiers.

You get both of us on every conversation that matters, from the first call through closing and well beyond.
