Theresa Groskopp, CN

Theresa Groskopp opened a nutritional counseling and consulting practice in her Appleton-area home after obtaining her Certified Nutritionist designation in 2004. She acted on her concern over seeing so much chronic illness in the Fox Cities and beyond, and her strongly held belief that "Your health is the best investment you'll ever make."

Previously, Theresa worked in the medical and social service fields after receiving a BA in Business from UW-Oshkosh — a valuable foundation for what happened next. With her ever-increasing interest in health, she juggled work and studied nutrition. She completed the Certified Nutritionist Program with the American Health Science University, National Institute of Nutritional Education.

After her home-based practice was started, client interest set in motion the retailing of nutritional supplements in her office along with the creation of a website and online store for Natural Healthy Concepts. She also gave nutritional lectures locally with area groups and offered employee wellness information to local businesses.

Every product at Natural Healthy Concepts is still rigorously curated and selected by Theresa. She continues to seek out reputable brands whose supplements are scientifically researched and clinically studied, and contain the purest ingredients. It is also important to Theresa that these companies follow Good Manufacturing Practices (GMP) and utilize socially responsible practices in the manufacture of their offerings (e.g., non-GMO, sustainably produced, cruelty free, etc.). She also goes to great lengths to avoid products with artificial sweeteners, colors and flavors, as well as those with chemical preservatives.

Having fulfilled her small dream with the success of Natural Healthy Concepts, Theresa continues to stay involved with the business, while also taking time to enjoy the great outdoors, her family and her good health.

Lori Bray-Levinsohn, CHHC

Lori Bray-Levinsohn was born and raised in a large family in Elkhart Lake, Wisconsin. Her family had the tradition of all sitting down for dinner together each night, and the meal usually consisted mostly of the typical Midwest diet of meat and potatoes — and, being in Sheboygan County, a lot of hamburger and brat cookouts with fresh corn on the cob from local farmers on summer weekends. She hopes to see that tradition of the family dinner return to homes everywhere. They also lived in a house right on Elkhart Lake, which kept them busy with a lot of outdoor and lake activities.

She moved to the Chicago area and worked as a Flight Attendant for 20 years. Lori stopped flying when she got pregnant with her son at 44 years young. She struggled with earlier pregnancies and miscarriages before having a healthy baby. Due to this, Lori became a stay-at-home mom, content to spend as much time with him as possible. As her son was getting into his double digits, she decided she wanted to do more to help and inspire herself and others.

Lori decided to become a Certified Holistic Health Coach and received her Certificate from The Institute for Integrative Nutrition (IIN). Through her struggles with pregnancies, she got inspired to help other women navigate their journeys to become healthier and happier and to become parents, as well as guide them in making better choices for themselves and their children’s health. Being an older mom has also made her realize the importance of staying healthy for your family, and she also has a quest to keep kids healthy and centered with all that kids face in today’s world.

At IIN, she studied dietary theories, contemporary health issues and topics, and Eastern and Western nutrition with some of the world’s top health and wellness experts. While recognizing each client's bio-individuality, Lori works with people, helping them discover their primary & secondary nutrition choices as they create a healthier lifestyle.

Lori loves getting out and doing activities with her family, especially watching car racing at Road America. She has taken up paddle boarding as a hobby and loves to get out on Elkhart Lake and Lake Michigan whenever she can.
