Owner and Broker of Sage Door Group, Nicki Thiessen was driven to create something that would help people find better housing solutions by fronting her company with integrity. More than 20 years ago she began her path in real estate as a mortgage loan processor. With her love of numbers and analyzing data she obtained her Real Estate Appraiser license and started a successful Real Estate Appraisal company in 1998. She sold that business when her family moved but continued in Real Estate, and held her Certified Residential Appraiser License in 5 states; giving her a wide variety of marking conditions. In 2016 Nicki received her Realtor license in the state of Missouri and began flipping houses, purchasing rental properties, and helping friends and neighbors buy and sell their homes. In 2018 she continued her education and has received her Missouri Broker’s License. Her love and passion for everything real estate continues to grow every day and she is excited to share her knowledge with other realtors, investors, homeowners, employees, and anyone who wants to listen!  Nicki and her husband live in Grain Valley and are active in their 4 children’s lives.  Their oldest son attends William Jewell where he plays soccer and is studying law and politics.  Their daughter played hockey at the AAA level for several years, and is now pursuing a career in Real Estate with ambitious goals.  Their youngest 2 children attend Grain Valley schools and are very involved in sports including baseball, Soccer, and basketball.  Nicki and her family enjoy taking summer vacations together, attending sporting events (obviously!),  and just relaxing at home together on rare occasions.  Nicki believes that the foundation of family, business, and all things should be faith in God.  That belief, along with her passion for Real Estate and work ethic created Sage Door Group!
