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.

Set back from the street for real privacy, this Wallingford townhome greets you with its peaceful flagstone garden patio and a slate-tiled entry. The lower level holds a half bath and a bedroom beside direct access to the rare attached 2-car garage (alley-accessed, so hauling groceries or gear home is effortless). Head up to the main level, where Brazilian cherry hardwood floors carry through the living and dining space, warmed by a gas fireplace, and the kitchen (granite counters, stainless appliances, an island for casual meals) becomes the natural gathering point. A balcony off the dining area brings the outdoors in and is perfect for morning coffee. Upstairs, vaulted ceilings and skylights flood both bedrooms with sunlight, and the primary suite, with skyline views, a jetted tub, dual-sink vanity, and a walk-in closet, feels like its own private escape. Just off the hall, a ladder leads up to a small loft, the kind of tucked-away spot made for reading, meditating, or losing an afternoon to a creative project. Hydronic radiant heat (recently serviced), a new water heater, a security system that stays, and fresh paint and carpet throughout mean the work's already done. NO HOA DUES, and the location does the rest: Walk Score 84, waterfront dinner at Westward, weekend coffee at Mas Cafe in Fremont, Green Lake and Gas Works park close by, and an easy Eastside commute via the RapidRide E Line or the Microsoft Connector shuttle three blocks away.
