About Us


The Langlois family business was successfully started by Jeffrey’s grandparents Les and Bertha Langlois at the urging of their son, Dr. Leslie Langlois, M.D. As a child, Dr. Langlois suffered from many health problems and encouraged his parents to open a health food store, because it was the “thing of the future.”

It is one of the oldest and longest running health food stores in the state of Wisconsin. The first store opened in May of 1946 on 27th and Center St. They regularly sponsored health expos in downtown Milwaukee at the Expo center with hundreds in attendance and lectures by Paul Bragg (well known author). Later they opened other locations. Les and Bertha ran all stores with the help of their daughter Marcie Kerschner, until the death of Bertha in 1983.

At this time Jeffrey purchased the family business. Since then the West Allis location has closed allowing the Brookfield store to expand into a successful nutritional consulting practice and retail store.

Beginning at an early age, Jeffrey Langlois also developed many health problems, similar to his father, who died of Crohn’s disease at the age of 37. After Jeffrey graduated from UW – Madison in 1983 with a BBA, Jeffrey returned to Milwaukee with hopes of improving his own health which had further deteriorated. Modern medicine proved to be of no help to him, so he began taking classes and doing a lot of his own research. It took over 15 years to build his health back to where he feels better today than he did when he was 20 years old.

Jeffrey Langlois has studied with the top holistic doctors in the United States, if not the world.

He is an Advanced Nutrition Response Testing practitioner, Certified Nutritionist, Certified Nutritional Consultant, Doctor of Traditional Naturopathy, Enzyme Therapist, Quantum Reflex Analyst, Quantum Biofeedback Specialist, Touch for Health – level II certified, and many more. Jeffrey’s passion is to improve the health and vitality of the world through better eating, proper supplementation and energy medicine.



Drew Detzner, BA, CNC, MH, graduated from Valparaiso University with a Bachelor’s Degree in 2006. Drew experienced several health challenges during his time in college that eventually led him to eating better, supplementing, and ultimately Nutrition Response Testing. His health improved dramatically, and Drew recognized that the he was not the only person who could benefit from these practices.

Drew has been on staff at Langlois Vital Nutrition Center since 2007 and started his nutrition practice in 2011 after going back to school.

Drew’s belief in the validity and effectiveness of Nutrition has led him to pursue ongoing education in multiple disciplines. He graduated from Trinity College in 2008 as a Certified Nutritional Counselor, and then again as a Master Herbalist in 2009. In March of 2012, he completed his certification as a Natural Health Practitioner. He is pursuing his Naturopathic Doctorate from Trinity and is concurrently enrolled at Mount Mary College and will graduate with his Master’s Degree in Community Counseling with a nationally recognized certification in Trauma and Addictions.
Drew’s passion is helping his clients achieve and maintain better health, and nothing excites him more than seeing success brought on by positive decisions.

For over 50 years, Langlois’ Vital Nutrition Center has been on the cutting edge of service and education in the Milwaukee area for health and wellness, always-putting quality, honesty, and knowledge above making a sale.
