Meet the Team
Matthea Rentea, MD
CEO, Board Certified Internal Medicine & Obesity Medicine Physician
Hi I’m Matthea, the owner and physician here at RMC! I have been a physician for over 10 years, and though I've worked with a wide variety of patients and conditions, have always found myself drawn to helping my patients achieve their best metabolic health and wellness goals.
A person’s inability to lose weight is often seen as a moral character flaw. As a physician I know that this stigma would never exist for a patient being treated for something such as asthma. Yet with weight, the standards are different. I aim to change that!
When I am not helping patients, I love spending time with my family and finding new ways to improve my own health and wellness! I enjoy meal prepping and am always trying new foods, and I love to get out and take evening walks with my husband, four year old son, and stepchildren.
I am here to work with you and approach the topic of metabolic health in a loving, compassionate way, helping you better understand and manage your health, and achieve your best long term results!

I'm Denise, a registered dietitian and certified diabetes educator. I enjoy working in health promotion. I am married to my husband John, and we have two adult daughters; Kate and Kimberly, and a pampered cat named "Grant".

Michelle Schultz, RD
My name is Michelle, and I’m a Registered Dietitian with over 20 years of experience helping individuals improve their health with nutrition. My goal is to offer practical strategies to assist those working to better their health through lifestyle behavior changes. I want to empower individuals with not only a better understanding of nutrition, but how to implement changes in a manner that is sustainable long term.
I’m a busy mom of 3 - ages 18, 17, and 14. My husband and I own a cattle farm, and to say that keeps us moving would be an understatement. I love to exercise and spend time in the kitchen. I’m an avid Illini fan and Cubs fan, and I cherish my family and friends.

I'm Adrienne, RMC's Office Manager! I am an organized and creative person, and I love the work I do here at RMC! I was raised in Alaska, so I enjoy spending my time outdoors.
