Sedenquist was president of Mohawk Management Corporation in Pasadena, California, and the former president of Sedenquist-Fraser Enterprises, Inc., which owned and operated a plastics factory. Sedenquist co-founded Commercial Pacific Bank in Santa Cruz, California, and served as board chair. She had served on the board of trustees on University of La Verne since 2010.

The Women's Civic League named Sedenquist as the Woman of the Year in 2011. From 2016, she served as the co-chair of the Scoreboard Task Force, a research committee affiliated with the City of Hope’s Center for Cancer and Aging, and composed of cancer survivors who provide information and feedback to a national group of oncologists working to develop new and improved patient care protocols for older patients with cancer. The University of La Verne endowed a scholarship in her name shortly after her death.

In her capacity as a real estate developer and broker, Sedenquist served as president of the Pasadena Association of Realtors, the Society of Exchange Counselors, and the Los Angeles County Boards of Real Estate. She served on the board of directors of the California Association of Realtors. She was the founder of the Foothill Apartment Association, a trade organization for property owners and managers.
