Get to know Sonya

Where are you from?

I moved around a lot as a military kid — from Vermont to Maryland to Colorado — and now proudly call Colorado home.

What do you do when you’re not at work?

I spend a lot of my time volunteering with animal rescues. I have three dogs, a cat, and often foster pups to get them ready for their forever homes. I also love biking, paddleboarding, and being outside.

What’s your approach to financial planning?

My goal is to make sure clients feel supported and taken care of at every step. I believe that being helpful, clear, and consistent makes all the difference.

What’s something most people wouldn’t expect about you?

I’m a certified scuba diver and a martial artist — I’ve always been drawn to things that challenge both the mind and the body.

Who do you love working with?

I love working with everyone — especially when I get to solve a problem or help someone feel more confident in their plan.

What’s one value that drives your work?

Empathy. I want every client to feel heard, understood, and cared for — no matter why they’re calling or what they need.
