When I started practice as a Nurse Practitioner nearly 8 years ago, I quickly realized two things. First, many patients were desperate to lose weight. In fact, I have heard many stories from patients saying that when they asked for help they were told to just eat less or a healthier diet, and exercise more. Unfortunately, many patients feel they alone are responsible for managing their weight loss and resort to treatments that have no basis in research. The second thing I realized was that I knew very little about what research-based treatments WERE available to help patients with weight loss. I quickly set out to learn all I could to help my patients. I was grateful to find the Obesity Medicine Association, a group of experts who helps patients achieve a healthy weight using up to date research. Since this time, I have committed my practice to helping patients achieve a healthy weight and improve metabolic health.


My favorite part about helping people achieve a lower weight and improve their metabolic health is that often other chronic health conditions like high blood pressure, high cholesterol, and diabetes also improve or resolve. I no longer prescribe medication just to treat one issue. I now incorporate nutrition, lifestyle changes, and medications in a way that addresses a person’s whole health and can even reverse disease. I have learned that there is no ONE treatment for everyone, and that for most people, weight is a chronic issue and must be treated this way.


Lori’s practice experience includes family practice, endocrinology, and comprehensive obesity treatment dealing with both medical and bariatric surgery treatment options. During this time, she achieved advanced education and certifications in both obesity and diabetes. She is currently accepting patients for weight loss, patients who have experienced weight re-gain after bariatric surgery, patients with thyroid disease who do not feel their symptoms are controlled, and those with prediabetes or diabetes who want to improve or reverse their disease.

If you’re in the Modesto or Stanislaus County area, you may know Lori from her years at Cornerstone Family Practice and Sutter Endocrinology.  She is currently working at St. Mary’s Bariatric Clinic in Grand Junction, CO.


Lori Wenz specializes in weight loss in Stanislaus County and all of California.

“I can’t believe that I was on hundreds of units of insulin and now with your help I do not need any insulin at all AND I have lost over 50 pounds!”

“ I appreciate so much that you are willing to help me with my weight loss in a way that I do not feel judged or pressured to make changes that I am not ready to make.  You have helped me make changes in my food choices that I can live with and I have lost 38 pounds!”

“I have lost 108 pounds in the past year and I feel that I have a completely new life!  I am able to do simple things that I couldn’t before like go shopping and not need to take the electric scooter.  I have energy at the end of a work day and want to go to the gym.  I am so thankful for your help.”

Carol Rowsemitt, PhD, RN, FNP-BC, FOMA

Board Certified Family Nurse Practitioner

Certificate of Advanced Education from the Obesity Medicine Association

Fellow Obesity Medicine Association

I love what I do. For almost 20 years, I’ve been helping people lose weight and keep it off on the Central Coast of California and now in Rhode Island as well. I was introduced to this area working with Dr. Thomas Najarian in his Los Osos practice. Dr. Najarian is responsible for ground-breaking work in inventing new medical, non-surgical approaches to weight loss. I worked with him to design approaches to thyroid treatment that make sense for many who struggle with symptoms of low thyroid which often accompany weight loss attempts.

With a bachelor’s in chemistry from Boston University and a Ph.D. in biology from the University of Utah, I came to nursing with an unusual background. After deciding to change careers, I received my bachelor’s and master’s degrees in nursing at the University of Utah, with an emphasis in diabetes care. In my years as a biologist, I worked in ecological physiology, studying how animals detect and respond to environmental changes such as day length, temperature, and food availability to determine when to breed or what time of day to be active. This background is highly relevant to thinking about the biological forces which drive us to eat as well as preventing weight loss with insufficient food.

​Carol has worked with fellow nurse practitioner Kris Dilworth, co-founding Diabetes Wellness Center, where she spent several years working in diabetes management and education. She then joined Dr. Najarian at his weight loss center in Los Osos. After he retired, she started her own practice in San Luis Obispo County, always working with a supervisory physician.

​The foundation of her approach to patients is understanding the challenges people face trying to lose weight and keep it off. Carol follows the scientific literature in this field and participates in Obesity Medicine Association twice-yearly conferences where she is known as “The Thyroid Lady” from her presentations to the group and persistent interest in explaining an ecological view of thyroid. She and Dr. Najarian published two papers in the online journal, Thyroid Science, providing an explanation of why they believe that most of the health care community does not interpret thyroid lab values appropriately, particularly for weight loss patients. (See Thyroid page on this website.)

She is accepting new weight loss patients, as well as with people who have thyroid disorders with or without weight issues. Many providers pay more attention to thyroid stimulating hormone (TSH) than to any other factor when evaluating thyroid.  Carol assesses a variety of lab values as well as listening to your report of symptoms to determine how to evaluate and treat thyroid problems.
