““Savannah has been terrific to work with. Dealing with gut symptoms was new to me and she was always knowledgeable on strategies and discussions on things I’ve read. Doing the food elimination diet was a challenge, but I couldn’t have done it without her guidance and encouragement. “”
— Oliver M.
“I could not be happier with the results I have seen since the beginning of my work with Savannah around my health and weight loss journey. Savannah is a kind presence, and exceedingly knowledgeable. She explained many concepts in ways that were easy to understand and incorporate into my own approach to my nutrition. I am now better equipped to manage my health in ways that seemed out of my control before.”
— Lyrra I.
“Savannah is a great listener and a wonderful source of knowledge. I especially appreciated the fact that it wasn’t a discussion just about food, but over all health and wellness. Left with a full grocery list and recipes. The best part was her explanation of what’s happening when I eat food and how and why my body can react the way it does.”
— Cassandra C.
“Before working with Savannah, I was stuck between constipation and diarrhea, and I was having acid reflux everyday. I was feeling nauseas, gassy, and so uncomfortable daily. I felt like I had tried everything from the low FODMAP diet and seen multiple dietitians and functional doctors without relief. Since working with Savannah, she has helped me through my issues and now I feel great! I can now eat more foods than before and don’t face daily constipation/diarrhea, nausea, and acid reflux.
Thank you for your help! I am so grateful! You helped change my life AND relationship with food!! ”
— Mia K.
“Before working with Savannah, I struggled for years with excessive loose bowel movements and gas, as well as nausea when laying down. I felt nervous when eating because I didn’t know what my digestive reaction would be. I needed to be prepared for frequent visits to the toilet, which left me feeling incredibly frustrated and confused. I went to a doctor who recommended I remove gluten, dairy, and nuts from my diet. The guidance reduced some digestion issues, but unfortunately didn’t make the significant difference I wanted.

Working with Savannah, I learned about gut health, and she helped me identify factors that were contributing to my symptoms. She started our session recommending a stool test; and based on the results, provided resources to include polyphenol, probiotic, and prebiotic supplements in my diet. She supported me through a journal app that logs daily food and activities; and taught me about the low FODMAP diet, nutritional goals and meal structure to make sure I was covering all the elements I needed to achieve healthy digestion. I also got a bunch of meal and product ideas and nutrition information that made a positive difference.

I now have more predictable, firm, and less frequent bowel movements, and seldom experience gas and nausea! I feel more confident each month with my food intake, am now less dependent on supplements, and have been able to eat some gluten, dairy and nut foods without noticeable issues. Such a big relief! I think the changes she helped me make will stay with me forever.

Thank you to Savannah for her role in my happier quality of life!! Highly recommend to anyone experiencing digestion issues!!”

“Savannah has helped me so much in my health journey! I came to her with stomach issues, absolutely no energy, and I needed to lose weight. She was able to meet me where I was and make doable suggestions to get me to where I am today! I have lost 30 lbs., I have more energy than I ever had before, and my gut issues have cleared up. I am so thankful to have worked with her”
— Dawn C.
“I have had chronic diarrhea for at least 50 years and was unaware of what caused it or of the existence of any help for it. After mentioning the problem to several doctors, a doctor gave some basic dietary information and medication, but not enough to stop the symptoms.

Savannah listened to my problems, helped me identify the causes, educated me about foods, gave me lots more necessary knowledge, and helped me completely end the difficulties that I had for many years I can hardly believe how much help she patiently gave to me.

Savannah REALLY listens! And, as a secondary benefit, I lost nearly 30 pounds. I recommend her very highly! ”
