Sequoia aims to provide every patient with a tailored and unique clinical experience, meeting each patient where they are in an effort to help them work toward the best version of themselves.
Create a world with the best medical and psychological care available to all we meet, wherever they may breathe.
Sequoia Integrative Medical Services was founded in 2020 by Dr. Mary Kate Friess DNP, FNP-BC, PMHNP-BC and Jennifer Vanden Heuvel. These visionaries had a dream and a mission of serving our aging population as best they could. Boom — Sequoia was founded, offering in-person and Telehealth medical services in assisted living facilities.
Mary Kate and Jen wanted to offer more comprehensive and individualized care to those aging in place. Many barriers exist that limit aging adults from receiving adequate medical care. Transportation. Resources. Weather. Physical limitations. Even fear.
Sequoia opened its physical headquarters in Kaukauna in 2020 amid the uncertainty of the pandemic. Incredibly, in 5 years, the business has flourished, growing from 0 to over 1700+ active patients and expanding to a service area that spans across Wisconsin and covers 200+ different communities. Much of the success that this business has experienced can be attributed to the dedicated team made up of nurse practitioners, RN’s, and LPN’s, who provide patients and families with peace of mind that medical care doesn’t need to be inconvenient.
