Nick sivek - commercial leasing specialist

Nick emigrated from the Czech Republic as a young child to the suburbs of Chicago where he spent most of his life. After earning a B.S. in Psychology with a specialization in Human Resource Management from Illinois State University, Nick's love of the outdoors brought him to Sedona for a year. Following that, Nick earned a Masters of Science Degree in Industrial-Organizational Psychology from Western Kentucky University and felt the call of Sedona. Upon arrival, Nick worked on small consulting projects in the hospitality industry in Northern Arizona while also teaching at Coconino Community College in Flagstaff.


In order to plant deeper roots into the community of Sedona, Nick received his real estate license and spent time working in property management before joining his long time friend Jack at McMahon and Miller Commercial Real Estate. Nick values the small town atmosphere and community bonds that are inherent to Sedona and his practice of real estate. In his free time, you might find Nick climbing rocks, at the gym, or picking up trash on the trails, and he will usually be with his dog, Tuba.
