Hello! Over the course of running my own interior design firm for the last 12 years, I frequently get asked about how I got my start in the industry. Today I wanted to share a real-world guide to becoming a designer — covering education, internships, construction knowledge, and what it actually takes to build a successful design career. I hope this is helpful, and please share this post with anyone whose considering interior design as a career path!

How to Become an Interior Designer

The real version—no fluff

So, you want to become an interior designe?

I love that. It’s an incredible career—but I’m going to be honest with you, it’s not just pretty fabrics and Pinterest boards. It’s long days, problem solving, managing people, budgets, timelines… and yes, a lot of really beautiful moments in between.

I got into this industry back in 2000, when I studied at the Design Institute of San Diego. This was pre-everything-digital—we were hand drafting, sketching, physically thinking through spaces. And I can tell you, that foundation still shapes how I design today.

There are a lot of self-taught designers now, and I respect that hustle. But for me, school gave me a level of technical understanding that I lean on constantly. It taught me how to think—not just how to decorate.

Cutting through the noise, if you’re serious about this career path, here are the top 4 things that really matter:

1. Get the Education (and Understand Why It Matters)

You can be self-taught—but you need to be honest about what you’re missing if you skip formal education.

School teaches you:

  • Scale and proportion

  • Color theory

  • Drafting (yes, even if it’s digital / AI now)

  • Space planning

  • Codes and technical thinking

That foundation gives you confidence. It allows you to walk into a project and actually lead it, not just style it.

And if you don’t go the formal route? Then you need to work twice as hard to learn those things on your own.

2. Work for Other People (Seriously—Do Not Skip This)

I know everyone wants to start their own thing right away. Don’t.

Working for other designers, architects, or firms is where you:

  • Learn how projects actually run

  • See real client dynamics

  • Understand timelines and mistakes

  • Figure out what kind of designer you want to be

I worked for small studios and also for an architect, where I was the only interior designer. That experience was everything. It gave me confidence and range.

Learn on someone else’s dime before you take on your own risk.

3. Learn Construction (This Is the Game-Changer)

If you want to be good at this—not just aesthetic—you need to understand how things are built.

I’m talking:

  • Plumbing

  • Electrical

  • Millwork

  • Installation timelines

  • How trades interact

Designers are the connector between all of these people. We are basically conducting an orchestra of trades.

And here’s the truth:
If you don’t understand construction, you’re always a step behind.

Go to job sites. Ask questions. Pay attention. This is where you become valuable.

4. This Job Is Hard Work (Like… Really Hard Work)

I don’t think people talk about this enough.

This job is:

  • Long hours

  • Constant decision-making

  • Managing clients, vendors, and contractors

  • Problem-solving all day long

I’ve worked my ass off to build this career. There’s no shortcut around that.

But if you love it? It doesn’t feel like a grind—it feels like building something meaningful.

5. Keep Learning + Build Your People

The best designers I know are constantly evolving.

I’m always:

  • Taking workshops

  • Learning from peers

  • Talking with architects and builders

  • Staying curious

And honestly, your community matters so much. Having other designers and creatives around you to share ideas, troubleshoot, and grow with—it’s everything.

Final Thoughts

Interior design is a layered career. It’s creative, technical, emotional, and strategic all at once.

There’s no one perfect path into it—but the designers who last are the ones who:

  • Put in the time

  • Learn the technical side

  • Stay curious

  • And aren’t afraid to work really, really hard
