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!

Brooke Simonson

Certified Nutrition Coach

I am a Nutrition Coach specializing in evidence-based, sustainable weight loss.

Unlike restrictive, one-size-fits-all diets that only provide short-term results, I promote science-backed nutrition & lifestyle habits that work for your unique likes, dislikes, and time constraints so you can lose weight permanently, have high energy throughout the day, feel completely in control of cravings, and stay consistent long-term!

Natasha Sullivan, CMA

Certified Medical Assistant

I'm Natasha Sullivan.  I have been a Certified Medical Assistant for 14 years.  I love my job and my patients.  When I'm not working I have 2 teenage children and 3 step children I keep up with.  I'm very passionate about fitness and nutrition so that's a huge part of my life and makes me so thankful to be apart of this team! 

Adrienne Butler

Office Manager

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 a lot of my time outdoors.  My hobbies include traveling, fishing and photography; which I love so much that I started my own photography business.  When I am not in the office, you might find me spending time with my family or playing pickleball with my friends!
