Nate knows this market from the water up. Years spent on the lake have given him a real feel for how people in the Okanagan live, and what buyers will pay for the lifestyle. This insight shapes how he positions every property, from lakeshore estates to luxury condos.
“There’s no substitute for aggressive promotion, real relationships, and knowing the market cold. Every home has its own story. My job is to find it, tell it better than anyone else, and negotiate like it matters, because it does.”
In addition to his core business, Nate leads a dedicated advisory for professional athletes and their families. For this clientele, discretion isn’t a bonus, it’s the job.
Whether you own a luxury condominium, a prestigious residence, or a world-class estate, Nate delivers a single point of contact directing with the whole picture, supported by an entire team executing quietly behind him.

The Marshall family has a proud history in real estate and farming dating back to 1911; Scott knows the area like the back of his hand and every possible detail that is relevant to a potential transaction in the Okanagan. Meanwhile, the Thorlakson side of the family dates back even further into the 1800s with a proud history of ranching and lumber.
Growing up in a household with parents working in the Okanagan Real Estate market, Scott developed a passion for the rapidly-evolving industry. His father, Lance, was a very successful agent for over 20 years in the Okanagan Valley. After spending his childhood in Lake Country, Scott moved to Vancouver to attain his Bachelors of Commerce degree from UBC, the #1 Ranked Canadian business school, obtaining a double specialization in both Real Estate & Finance. Along with his formal education specializing in real estate, Scott has relevant experience with the Commercial Real Estate Development Association in Vancouver, and as a manager at the largest cherry operation in Canada.
After completing his four years of formal real estate education and starting his career as a fully licensed REALTOR®, Scott quickly obtained his trading services license in additional to his broker’s license.
After 8 years at a large international real estate company, achieving the top sales position out of its 200+ agents locally and #2 in sales for British Columbia, Scott transitioned to Sotheby’s International Realty Canada.
A large percentage of his business comes through repeat business and the referrals of satisfied clients. This is due to a high level of detail, accuracy and professionalism that is maintained while assessing and assisting clients with their real estate needs.
Scott has sold over $300,000,000.00 in real estate and has been involved in some of the most significant and unique transactions in the Okanagan Valley. In 2025 alone, he introduced the buyer for the largest residential sale in the Association of Interior Realtors’ history at the time and was involved in two of the three highest-priced sales of 2025 within the Association.
