Sequoia Integrative Medical Services was founded in 2020 by Dr. Mary Kate Friess DNP, FNP-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 4 years, the business has flourished, growing from 0 to over 900+ active patients and expanding to a service area that spans across Wisconsin and covers 60+ 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.

I’m Allison, a Family Nurse Practitioner. I recently graduated from Concordia University Wisconsin and am board-certified by the ANCC. I am born and raised in the Green Bay, WI area, and have been practicing in health care since 2009 in various roles.
Throughout my career, I have been dedicated to providing patients across the lifespan the right care at the right time, primarily working in skilled nursing facilities, assisted living facilities, and home health. It has become increasingly apparent to me that these three areas of healthcare have some of the highest disparities, and I am looking to positively change this.
