For over 20 years, CertainPath has been helping independent contractors build businesses that impact their communities and the lives of their teams.
At CertainPath, we help HVAC contractors, plumbing contractors, roofing contractors, and electrical contractors grow thriving businesses. Since 1999, our mission has been to positively impact the lives of independent contractors through proven systems, expert coaching, and contractor-focused tools.
We’re not just a trades business coach—we’re a member-owned community of industry leaders. Our founders, Rebecca and Lon Cassel, are contractors themselves, running one of the most successful HVAC businesses in Illinois. Along with other owners, they built CertainPath into the largest contractor network in North America.
What sets us apart? It’s more than HVAC business coaching, plumbing sales training, or electrical contractor software—it’s the members. At our events, contractors open their doors, share what works, and help each other succeed.
With CertainPath, you gain more than business tools—you join a network committed to building lasting, profitable home service businesses.
Rebecca Cassel started in contracting in the mid-90’s as a consultant, later starting her own HVAC business, which she sold. She joined Clockwork Home Services, eventually becoming Group President, overseeing $180M in residential HVAC, plumbing, and electrical sales. In 2014, she and her husband Lon bought CertainPath. Through Rebecca’s leadership as President, she has ushered in a new era for the company, while overseeing its incredible growth.
Lon offers over 45 years of experience in contracting. At one time, he operated 7 different companies in 4 states with an average of 18.6 % pretax profitability. He later sold 3 of those companies to the first publicly traded HVAC company in the nation. He then became a consultant with an expertise in sales, training, and acquisitions. In 2013, Rebecca and Lon started Cassel Heating & Cooling. In 2014, Rebecca and he bought CertainPath. Today, Lon offers insight and guidance to the organization and its members.
Gus Antos joined CertainPath as a member and, alongside his father-in-law, transformed Milestone from a struggling operation into one of the most recognized home-services brands in the Dallas–Fort Worth market. By installing CertainPath systems and a people-first culture, Milestone scaled rapidly in revenue and profitability and is consistently celebrated as a “best place to work” in DFW.
A third-generation plumber, Jimmie Dale led Baker Brothers through a pivotal shift—from niche leak detection to a full residential service model—after market dynamics changed. After joining CertainPath for guidance, he implemented operational and marketing systems that drove substantial, sustained growth in both revenue and margins. Baker Brothers is regularly cited as a top workplace in its market and later became part of Wrench Group, with Jimmie continuing to serve as President.
As steward of a multigeneration, family-owned company, Tim Boulden repositioned Boulden Brothers around residential HVAC, plumbing, and electrical service and replacement. With CertainPath’s playbooks, he re-engineered pricing, marketing, and service processes—producing steady expansion in revenue, strong customer loyalty, and durable profitability while maintaining the company’s neighbor-first reputation.
