For me, real estate is about more than buying and selling homes—it's about building relationships, earning trust, and helping people confidently step into their next chapter.

As an educator at heart, I enjoy simplifying complex processes and empowering others to make informed decisions. Whether guiding first-time homebuyers, helping families prepare to sell, or answering questions along the way, I believe every client deserves to be heard, respected, and supported throughout their real estate journey.

With more than 10 years of experience in marketing, I understand the value of strategic planning, effective communication, and showcasing every home's unique story. My background in the arts has shaped my appreciation for creativity, thoughtful design, and attention to detail—qualities that help me present properties in their very best light.

Beyond real estate, I enjoy serving my community through education, volunteer work, and creative pursuits. These experiences have strengthened my belief that every interaction is an opportunity to make a positive difference. I strive to serve each client with integrity, patience, professionalism, and genuine care.

Whether you're buying your first home, searching for your forever home, investing, or preparing to sell, my commitment is to make the experience as smooth, informed, and enjoyable as possible.

Proudly serving Western Washington and beyond.

Because home isn't just where you live—it's where life happens.

Home Changes Everything.

Rare opportunity to own 1.12 fully usable acres in the highly sought-after Issaquah School District. This secluded, build-ready homesite in the Renton area skips some of the biggest hurdles vacant-land buyers face. The RA-5-zoned lot already has power, water, and a two-bedroom septic system on site—improvements that can cost tens of thousands of dollars and add months to the process when purchasing raw land. The septic may also be upgradeable to support a larger home, offering added flexibility. With 48,787 square feet, there is room to thoughtfully position a home among mature trees, enjoy the existing privacy, or potentially add a future shop, barn, or guest space. King County’s rural RA-5 zoning offers more breathing room and flexibility than a traditional subdivision while keeping you close to Renton and Maple Valley conveniences. Move from purchase to design and permitting without starting from scratch on utilities and site improvements. Ideal for a future homesite, custom build, or investment. Create a private retreat with space to spread out, pursue hobbies, garden, or enjoy a quieter setting while staying connected to nearby shopping, dining, recreation, and commuter routes. Secluded, fully serviced acreage in the Issaquah School District is increasingly hard to find. Buyer and buyer’s agent to verify all information, including school-district boundaries, septic capacity and upgrade requirements, permitted uses, access, and county development requirements.
