CAROL BANISTER

RD/LD, MS, CDE
Founder Banister Nutrition LLC

Carol is the owner and founder of Banister Nutrition LLC. She opened the doors in 1981 and has been a trailblazer in the field of Nutrition and Dietetics in Oklahoma City and the surrounding areas ever since.

After completing her nutrition and dietetics education at Kansas State University, Carol was recognized by her alma mater as Entrepreneur of the Year and served on the Kansas State alumni board for the College of Health and Human Sciences. She was president of the Oklahoma Academy of Nutrition and Dietetics and worked with the Oklahoma Eating Disorder Association as a pioneer in the field of eating disorders. Carol has also served on the internship board at Oklahoma State University.

As the founder and owner of Banister Nutrition, Carol spends a considerable amount of her time managing the practice, which continues to grow and thrive. She says she is elated about the outstanding quality of the Banister Nutrition team and the way everyone works together to provide excellent medical nutrition therapy to patients across the state. Everyone on the BN team is dedicated to the support of their patients, providers, and each other.

After 42 years in private practice, Carol still loves working with patients when time allows. Her approach with patients is unique because of the care she takes not only to understand their food choices, but also to understand the impetuses behind those choices. Food is the core of health, and for many people, food choices are guided by lifestyle and emotional factors.

Carol is a Certified Diabetes Educator, which is a great complement to the nutritional guidance she provides to patients with diabetes.

In her spare time, Carol enjoys biking, hiking, working in her flower beds, trail walking, or traveling. She says the things she enjoys most are spending time with her son and his family in Edmond, or her daughter and her family in Denver.

“On a daily basis I get to hear about and participate in the process of people making changes with thinking, self -talk, behaviors, food, nutrition and movement. They get happier, healthier, more energetic, and empowered. I will never in a million years tire of watching this transformation in the lives of those who have trusted us.”

DOMINIKE ROUNDS

RD/LD
Registered Dietitian

Dominike’s past involvement in sports, including cross country, basketball, soccer and volleyball, made her very aware that athletic performance was directly influenced by food intake as the source of fuel. She learned early in life that food and nutrition affect physical as well as mental health.

Dominike is personally acquainted with the challenges to finding peace and joy in our relationship with food. She says, “Food is a source of celebration and brings us pleasure – and pleasure is good medicine.” She takes an ‘all foods fit’ approach, advocating neutrality in our perception of food and bases her guidance on evidence-based research. Dominike says her desire is for her patients to feel confident in their food choices, which will result in positive and sustainable behavior changes, whether dealing with diabetes, gastrointestinal issues, heart conditions, weight management or any other nutritional/health concern.

Dominike grew up in Arizona, graduating from the University of Arizona with a degree in Nutritional Sciences. She moved to Oklahoma to complete her dietetic internship program at the University of Oklahoma and remained to work in the clinical nutrition field prior to joining Banister Nutrition.

Her own journey of recovery from an eating disorder inspired Dominike to become a dietitian. She is very open about her experience with an eating disorder and hopes to inspire those struggling with any disordered eating patterns:

“My eating disorder was fueled by social media influencers in addition to pressure to fit a specific athlete aesthetic. I believed my restrictive eating was ‘healthy’ and good for my body. I was brainwashed with misinformation. I found secretive ways to hide my eating disorder, which caused me to be isolated. I couldn’t enjoy valuable time with my family and friends. My journey to recovery was not easy by any means. Just eat more — if it were only that easy. I sought help from a team of professionals that included a dietitian. They gave me a safe space to heal and made me feel heard and valued for once. The dietitian gave me courage to face my fear foods while helping me find coping mechanisms to fight the voice in my head that was telling me to go back to old habits.”

The recovery journey was a far greater challenge than Dominike ever expected, with far greater rewards than she ever imagined. She knows her personal experience in the depths of despair with an eating disorder followed by full recovery has provided her with a great depth of knowledge, unique understanding, and authentic compassion to work with those struggling with any type of issues with food.

Dominike now has healthy respect for her body and practices daily affirmations to support body positivity. In her spare time, she likes outdoors with her husband and one-year-old son, working in occasional runs when she can, exploring local coffee shops, grabbing a burger at S&B Burgers, or enjoying some slices at Hall’s Pizza Kitchen.

“It’s so rewarding to have a positive impact on someone’s relationship with food. I love being a part of each person’s unique health and fitness journey. When they experience improved lab values, more energy, and no more gut discomfort, it never ceases to make me smile. These experiences are why I love what I do.”

ANNIE THORP

MS, RD/LD
Registered Dietitian

Annie has worked with people of all ages and walks of life in achieving their nutrition and health goals. In the past she counseled families and individuals with a variety of health goals as the dietitian at a community health center in rural Oklahoma and the supervisor of their Women, Infants, and Children clinic. Following that she worked at a private practice on the East Coast counseling her patients and running a diabetes support group.

Annie attended the University of Central Oklahoma and graduated with her Masters of Science in Nutrition, Dietetics, and Food Management. As someone who grew up enjoying cooking (and especially baking!) and was also intrigued to learn how food affects the human body, she decided to take a nutrition class in undergraduate, and from then on she was hooked! During her internship she knew she wanted to educate patients in an outpatient setting, and has since then deeply valued incorporating a therapeutic approach to nutrition practice.

Each of us is on our own journey at our own pace, and Annie considers it a joy to support and collaborate with her patients to find practical sustainable ways to achieve their unique goals. It is her passion to build a relationship with them based on trust and compassion.

In her free time, Annie loves soaking up Oklahoma’s bountiful sunshine with her family, taking walks or going to coffee with friends, singing and playing the piano, and reading Curious George and Narnia books with her four kiddos.

“I so enjoy watching things ‘click’ for people, whether it’s learning more about how their bodies work, or strategies that they find fit just right for them in their current moment.”

RUTH SIMON

Student Intern

Ruth is currently a senior at the University of Central Oklahoma and pursuing an undergraduate degree in Nutrition and Dietetics. Her goal after graduation is to pursue a Master’s program in hopes of becoming an occupational therapist for pediatric patients. Ruth developed a passion for nutrition through her curiosity to learn about healthier preparation techniques that can help her family and church community in their preparation of cultural South Indian food. Looking from a patient’s perspective is what Ruth wants to do when helping her patients achieve healthy, strong lifestyles. She is blessed to be working with an amazing group of women who are compassionate about helping others, and she is excited to expand her knowledge in nutrition and patient care.

When Ruth is not busy with classes or helping with creative content for Banister Nutrition, you can find her serving in worship, media, or children’s ministry at her church, sipping on an iced latte while reading the Bible at a local coffee shop, or hanging out with friends or family eating takeout and enjoying pleasant conversations.

“Just as each part of the body does its own work, making the whole body grow and be strong with love, I believe that each position in the healthcare field plays a role in a patient’s journey to have a healthier and happier life. I am looking forward to this next season with Banister Nutrition for experience with patient interaction, knowledge about nutrition, and tips for growing relationships with my patients and co-workers.”
