Talking Points

Recent interactions between the hosts and their guests.

EP261 From Journeyman to Trainer: What Actually Works and Why With Don Gillis (February 2026)
Q: What was the turning point that pushed you toward becoming an educator and trainer rather than staying strictly in service?
The turning point was recognizing that teaching others, sharing experiences, and building durable skills could have a bigger, longer-lasting impact than climbing the next corporate rung, especially after seeing how much people learn when you invest in their growth.
EP261 From Journeyman to Trainer: What Actually Works and Why With Don Gillis (February 2026)
Q: Going back a little bit, when you say you built the service department, what did you draw on for ideas, for process, for method to build the service department?
I leaned on the owner for training opportunities, self-taught the rest, and used a combination of soft-skills training, structured outreach, and relationship-building to transform the department, literally starting from a blank canvas and expanding through persistence and practical experimentation.
EP261 From Journeyman to Trainer: What Actually Works and Why With Don Gillis (February 2026)
Q: Would you say those soft skills, those listening skills were a big game changer in your career?
Absolutely. Soft skills, especially listening and being genuine, formed the foundation of trust with customers and colleagues, enabling me to grow beyond technical ability and become an effective trainer and leader.
EP257 From Rockets to Heat Pumps: Shreyas Sudhakar on Scaling Quality HVAC (January 2026)
Q: What's probably one of the biggest things that you find that homeowners don't necessarily understand about heat pumps?
A lot of people frankly don't know what a heat pump is or they don't know that it exists to begin with.
EP248 Balanced Comfort, Brutal Lessons: Scaling, Losing Half Your Revenue, and Starting Over with AI with Aaron Husak (November 2025)
Q: What advice do you have for evaluating support staff?
Attitude is more important than aptitude; ensure that you're carefully evaluating office and technical positions alike.
