MEET THE TEAM


Heidi Peterson, RN
Heidi is a registered nurse who has previously worked in family practice, health coaching, IV therapy, and as a clinic manager for a small clinic. She has an intense passion for integrative care and a pure love for learning. Heidi’s passion for true integrative care began when she became a mother to children who required more than allopathic medicine could offer. This passion and love for learning allow her to grow personally and professionally while attending additional integrative conferences and gaining certifications along the way. She is a wife and mother of three active children who enjoys all things involving nature and family. You will find her cheering on her children in their life adventures, camping in the summer, and hiking with her dog year round.

Sandra Homan, NP
Hello! I am a Nurse Practitioner with eight years’ experience in Family Medicine and Urgent care. I graduated from the University of Illinois Chicago with a Masters of Science in Nursing in 2015. During my time in family practice, I have encountered many individuals with chronic illness and crippling complaints. Frustrated by the limitations that insurance and Western medicine hold, I began my journey to seek more.
Although constantly learning, I deepened my understanding and appreciation of integrative medicine when my daughter was diagnosed with Leukemia at the age of 3.5 years old. While researching ways to support my daughter on her journey knowing that her body would be need more than what Western Medicine could provide, I discovered Zuza’s Way Integrative Care. Dagmara helped our family safely navigate her journey and now she is thriving. I hope as a consultant and Provider with Zuza’s Way I can have the same impact while helping families to navigate staying healthy and finding the true meaning of wellness.

Kari Best, PA-C
Hello! My name is Kari, and I am a Physician Assistant, Registered Dietitian, breast cancer thriver, auntie to three beautiful nieces (my favorite role), triathlete and lifelong student of health, fitness, and nutrition.
My journey into integrative and functional medicine started after I was diagnosed with breast cancer in 2015. I completed the standard of care therapies recommended for me then started on a quest to determine the cause of my cancer. I knew I needed to make changes in my life, but I didn’t know where to begin. Thankfully, this led me to the book The Metabolic Approach to Cancer by Dr. Nasha Winters.
Dr. Nasha’s emphasis on the importance of both assessing and optimizing one’s terrain on the road to recovery transformed my understanding of cancer and my approach to practicing medicine. Now I strive to get to the root cause of medical issues and focus on prevention when possible. I am grateful to have had the privilege of studying with Dr. Nasha and working with Dagmara during this process and I am thrilled to be joining the team at Zuza’s Way Integrative Care. I look forward to supporting others on their unique journeys toward healing.

Jeanne Tregilgas
Hello, my name is Jeanne and I am a patient advocate at Zuza's Way Integrative Care. I began patient advocacy as my own advocate when I was diagnosed with lymphoma in 2019.
My personal journey with cancer led me to enroll in the first cohort of Dr. Nasha Winter's Terrain Advocate Program. Along with my enrollment in terrain advocacy, I have continued my education in health coaching and functional nutrition.
Prior to my cancer diagnosis, I worked in the health and wellness field as an Assistance Wellness Director for the YMCA, personal trainer, and strength and conditioning coach. Along with my work in health and wellness, I served full-time as the Program Director of a children's ministry.
I understand how overwhelming a cancer diagnosis can be. My role is to help you understand and implement a better way of cancer care.
