When she and her husband started a family, they moved back to her hometown of Ann Arbor, and Sierra brought her client-first commitment home with her.
With more than 20 years of experience in residential real estate and a master's degree in human services and counseling, Sierra works with buyers, sellers, relocation clients, first-time homebuyers, and investors across Ann Arbor and Washtenaw County.
