Nancy Madynski—the visionary behind our work at Nancy Built—is a proud San Francisco native, born and raised in the Mission. Deeply committed to her community, she strives to enhance cultural richness while reducing environmental impact. Nancy spearheaded the Dolores Park Playground renovation and consistently contributes to local historical preservation and restoration projects.

A trailblazer in San Francisco’s construction community and the Bay Area’s first female Certified Green Builder, Nancy has shattered glass ceilings and mentors countless women in traditionally male-dominated industries. When she’s not leading transformative projects, she enjoys gardening, exploring the arts, discovering local eateries, and endeavoring to find or make San Francisco’s ultimo taco.

NANCY MADYNSKI

General Contractor / Principal
I initially became a contractor and San Francisco’s first female green builder out of a passion for the environment, but my true calling is bringing someone’s dream remodel to life.
SANDRA

Operations Manager

Working at Nancy Built is seriously the best. Nancy knows her stuff and always has your back, which makes it easy to learn, grow, and actually enjoy coming to work. It’s a place where you get things done, have fun doing it, and feel like part of a team that truly cares.

JAMES

Project Manager
Nancy is truly amazing to work with! It’s nearly impossible to narrow down my reasons, but if I had to choose, the top one would be that she has built a company where every crew member can thrive and feel supported.
JOSE “CHINO”

Carpenter

I love working with Nancy at Nancy Built because she creates an inclusive environment where everyone feels comfortable, valued, and heard. Our team works well together, we all learn from each other on the jobsites, and we’re lucky to work with some truly great clients. It makes every project feel like a team win.

Apprentice Carpenter

I love working at Nancy Built because the company offers me endless opportunities to learn and grow, thanks to a leader and team that consistently support one another.

BRYAN

Site Supervisor

I became a site supervisor because there’s nothing better than building something from the ground up and stepping back at the end of the day to say, “We did that.” I joined Nancy Built because Nancy and I are on the same page—we care about quality work, happy crews, and making cool things happen. The whole team is awesome: friendly, skilled, and just fun to be around. I’m excited to be part of it!

ZIGGY

Canine in Chief

Hi, I’m Ziggy—the Canine in Chief and all-around good boy at Nancy Built. Every morning, I hop in the car with my mom, Nancy (she’s the boss), and head to the jobsite. I handle important tasks like greeting the crew, inspecting the work, supervising snack breaks, and finding the best sunny spot for a nap.

When I’m off-site, I’m holding down the office—getting belly rubs, sneaking cookies, and keeping an eye on those suspicious tape measures. I take my role seriously, because every great construction team needs a little fur and a lot of heart.
