Principal of Stockton, Cal.-based KTJ Design Co., Kathleen Jennison turns challenges into collaborations through leadership and business savvy.
How has your background influenced the way you approach the design business?
Kathleen Jennison: My CPA background trained me to think in systems. In audit, you don’t just “do the work”, you build a repeatable program with clear steps, checkpoints, documentation and accountability. That’s exactly how I run design projects. Clients get a structured process, clear decisions at each stage and fewer surprises because everything is planned, reviewed and tracked.
What has been your biggest challenge in the design business – and how did you overcome it?
Kathleen Jennison: One of my biggest challenges has been earning the trust of general contractors who’ve had difficult experiences with designers in the past. A lot of that comes down to technical accuracy and communication. I overcame it by speaking the construction language, producing clear drawings and specifications, and being decisive. When trades see that the information is accurate and the process is organized, the relationship shifts from skepticism to true collaboration.
What is the most important career lesson you’ve learned?
Kathleen Jennison: Clients don’t hire a designer for more choices, they hire a designer for leadership. The most important lesson I’ve learned is that confident guidance is part of the service. When I lead decisively, clients feel less overwhelmed and projects move forward.
What advice would you give someone who’s looking to enter the design business?
Kathleen Jennison: Treat it like a real business from day one. Know your numbers, understand contracts, build a clear process and price your time properly. Talent matters, but sustainability comes from systems.
In your own home, what is your favorite kitchen or bath feature – and why?
Kathleen Jennison: My favorite kitchen feature is my Carrara white marble countertops. After going to Rome and learning that the marble at the Vatican is thousands of years old and still looks stunning, I fell even more in love with it. Sure, after a couple of years my countertops show a little wear and tear, but I actually love that. It makes my 85-year-old home feel more authentic, and it makes me smile every time I walk into my kitchen.
