Samantha Penlington Headshot Nutritionist & Registered Nurse

Samantha is a Nutritionist and Registered Nurse, and is currently pursuing further education to obtain her Registered Dietitian license. Prior to attending Western University to obtain her second degree in Foods & Nutrition, she completed a Bachelor of Nursing Science degree through Laurentian University.

Samantha has extensive experience working as a Registered Nurse before deciding to pursue a second degree in nutrition. She has a wide variety of patient care experience in various healthcare settings, particularly in critical care and public health. She also spent a year working at a Digestive Health Clinic, where she worked on developing educational resources for people struggling with irritable bowel syndrome (IBS), GI disorders, and those following a low-FODMAP diet.

Carly is a black labrador retriever who has been with NutritionRx / CrossFit London since 2009. Originally fostered by Jen & Dave to become trained as a service dog for a child with autism, Carly was released from Autism Dog Services because of her overly-friendly personality (as if that’s even a flaw), and was adopted permanently into the family.

Carly’s hobbies include chasing balls and sticks, snuggling with her favourite humans, and offering kisses and tail wags to new clients. She usually sleeps in the corner of the NutritionRx office on her bed during client nutrition counselling sessions. If you have an allergy or fear of dogs, please alert our team prior to your initial assessment and arrangements can be made to have Carly stay at home.
