About Us

/ Welcome to Beachside Custom Gyms

OUR WHY

Our mission is to create elevated fitness spaces.

We are challenging the status quo of home gyms so that it feels intentional & inspirational, not an afterthought.
We believe in guiding our clients through a better, more transparent, and more thoughtful gym design & build process so it’s collaborative & fun, not adversarial.
Ultimately we enjoy building spaces for health and happiness because we thrive on making a positive impact in your life, and for the communities you serve.

We are pumped to work with you!

Due to our unique skills and background, some have even called us a triple threat (Fitness Industry Experience, Contracting Knowledge, AND Design Expertise).

This allows us to create truly life changing spaces for you, or for your fitness community and clients.

WE HAVE GYM DESIGN DOWN TO A SCIENCE

We are the only design and build firm in Orange County specializing in home gyms and small commercial spaces.

WE GEEK OUT ON GYMS

With over 20 years of experience planning, designing, outfitting, and building fitness spaces, we know how to make your space shine. When all is said and done, it must pass the vibe check.

FULL SERVICE DESIGN

We design everything starting from the open stud walls, to styling the finished space, and every squat rack and dumbbell in between so that it feels like YOUR space.

FIXED COST PROPOSALS

We avoid the traditional smoke and mirrors approach of builders and contractors at all costs. Instead, we like to approach things with full transparency because nothing means more to us than your trust.

Did You Know?

Research shows that exercise has positive effects on every aspect of our lives – including better relationships, a healthier mental attitude, and improved actualization of your goals. Investing in a fitness space in your home will pay dividends that you haven’t yet imagined.

Prepare to be blown away!

I’m Kali Sudbrook, founder of Beachside Custom Gyms, and I’m stoked you’re here.

After 12 years as a Fitness Director at UC Irvine, I left the comfort of a steady career to create something different: gyms built with the same focus and grit as the people who train in them. As both an interior designer AND licensed contractor – with more than 20 years in the fitness industry- I bring a rare skill set that blurs the line between builder, designer, and fitness pro.

Here’s what I believe: your workout should be the easiest part of your day, not the hardest. That’s why my team and I design and build gyms that remove friction, spark motivation, and actually help you hit your goals. We balance the how—construction, layout, and flow—with the why—routine, energy, and consistency.

The best part for me? Tapping into your vision, obsessing over the details, and watching you step into a space that feels like an extension of your mindset. So if you’re ready to raise the bar for your home gym, let’s build something stronger, together.
