Our Mission


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.

Our Vision


Create a world with the best medical and psychological care available to all we meet, wherever they may breathe.

Our History


Sequoia Integrative Medical Services was founded in 2020 by Dr. Mary Kate Friess DNP, FNP-BC, Jennifer Vanden Heuvel, and Chad Weston Gardner MSW/CAPSW. These three 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 and psychological services in assisted living facilities.
Mary Kate, Jen, and Chad 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 2021 amid the uncertainty of the pandemic. Incredibly, in less than 3 years, the business has flourished, growing from 0 to over 400+ patients and expanding to a service area that spans from Beaver Dam to Green Bay and covers 21 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.


Meet the compassionate and dedicated Sequoia team. We are a group of experienced medical professionals who are here to support and uplift you or your loved one in their journey. With a shared commitment to providing exceptional care, we are ready to lend a helping hand, a listening ear, and a warm smile. Trust us to be your companions on this path, dedicated to enhancing the well-being and quality of life for each individual we serve. Let us be your trusted partners in elder care, ensuring comfort, dignity, and personalized support every step of the way.

Allison from Sequoia

Allison Rutten, APNP, FNP-BC

I am 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.

Pam from Sequoia

Pam Leplavy, RN

Hello! My name is Pam and I have been a registered nurse specializing in geriatric and mental health since 2010. I was fortunate enough to be Sequoia’s first nurse, and so proud of the growth, success, and team that is now in place. I love my job and my work family…along with all the patients, families, and facility partners I come in contact with. Like they say… It is truly not a job if you love what you do.

In my non-working hours, I prefer to be a homebody or spend time with my two grandchildren, Beckham and Chandler. I live in the Appleton area and would love to get to know you and your families!

She has specific experience with dementia and Alzheimer’s, as well as a passion for psychiatric care/mental health for all ages.

Heather from Sequoia

Heather Aland, LPN

I have been in the healthcare field for 19 years. I was born and raised in Kenosha County, Wisconsin, and I moved to the Green Bay Area 13 years ago to pursue my nursing dreams. I graduated from NWTC in 2015 as an LPN.

Starting at a very early age, I’ve had a burning desire to help others. I became a CNA as soon as I could. I spent my younger years working in group homes, TBI hospitals, and in home health. Since becoming a LPN, I have focused on our aging population and their quality of life and care. I set out each day looking for opportunities to make someone’s day better.

With Sequoia, we work closely as a team, making each interaction a priority. From Triage, Telehealth and in-person visits, our team is dedicated to you every step of the way.

I love exploring the benefits of essential oils and their positive impact on body, mind and environment, and going on long rides on the motorcycle with my husband. My four children and 11 grandchildren are the center of my world.
