The PORTH Story

Personalized sammamish

Early in his residency at the University of Washington, Dr. Rooz and his wife went for a hike east of Seattle.

On the way home they stopped at Homegrown in Sammamish, and immediately felt something for this place. Dr. Rooz loved the Sammamish small town feel, with a diverse population and a strong sense that it was on the brink of change. This town was growing in leaps and bounds, and he wanted to be a part of it.

A few weeks later, Dr. Rooz's real estate broker introduced him to TRF Sammamish Project and the rest is history!
