Sarah Johnson – Broker 

Sarah’s favorite part of her job is building strong relationships with her clients to ensure a calm and smooth process for everyone involved.

By listening to her client’s needs and concerns, she can guide them through the process of buying and selling with ease. Sarah brings integrity, enthusiasm, hard work, kindness and joy to every detail of her real estate transactions.

Born and raised in Portland, Sarah knows the city and surrounding areas extremely well. A Wilson High School alum herself, her three kids are now on track to attend Wilson too, as Sarah has settled back into the SW neighborhood where she grew up.

Before moving back to Portland, Sarah and her husband moved 7 times in 8 years, so she understands the transitions of moving, finding a home and relocating, and wants to help ease that process for her clients.

When not working, Sarah can be found volunteering at her kid’s schools, in her community, and at her church. She also loves to spend time in the kitchen cooking and baking, and hanging out with friends and family. Sarah values giving back locally and globally, and a portion of all her sales go to Embrace Oregon and Haiti Foundation of Hope.

D. Kolin Better – Broker 

Stock Photo by Wellness Stock ShopWhether buying a home for the first time or investing in multi-family real estate, Kolin believes that the key to his success is a balance of business acumen and emotional intelligence. With a wealth of experience as a builder of businesses across multiple industries, including commercial real estate, technology, and hospitality, Kolin brings to the table a calm wisdom borne of high pressure situations.

Becoming a residential real estate Broker has allowed Kolin to use his experience to impact people’s lives in a direct and personal way, cutting through the potential stress to find a smooth and seamless way forward.

Kolin lives with his wife, child, and menagerie of pets in inner Southeast Portland. When not working, he enjoys the outdoors, cooking, cocktails, sporting clays, and lacrosse.  He can also be found hopefully waiting (and waiting) for his beloved Alma Mater (Tulane University in New Orleans) to field a decent football team.

Kolin has pledged to donate a portion of every commission to the Happy Hippie Foundation, which rallies young people to fight injustice toward vulnerable populations nationwide.
