“Kiera is outstanding. She really listens to my concerns and is open to change anything in the plan at any time if it is needed. If you are on a budget, she understands and helps guide you. Bettering your health and eating better is not as expensive as you think if you have someone like Kiera by your side helping you. She was always so encouraging, understanding, and helpful. I recommend her to anyone who is looking to speak with a nutritionist. Having PCOS, losing weight is a challenge in itself. She was determined to find foods and lifestyle changes related to PCOS patients to ensure it was helping. I cannot recommend her enough!”

Kiera does a fantastic job to not only provide recommendations but also the science behind them. I had a much better understanding of the different factors that could be contributing to my health concerns just after 1 session! Kiera has also laid out a plan and timeline for how we will work on each of my concerns. Highly recommended!

I had an amazing experience working with Kiera. I have been experiencing a variety of digestive and bloat problems for years that other healthcare professionals hadn't taken seriously or spent the effort trying to diagnose. Kiera really listened to my case and was able to start implementing changes that have already helped significantly improve my symptoms. She was very attentive and was able to see me as a human and not just another case. Couldn't recommend her enough!

Kiera helped me look at my nutrition from a bigger-picture point of view, and was happy to take time to educate me so that I could be more aware of the nutritional implications of food choices I make. She also gave me great practical advice for shopping and meal planning. Now I’m more aware, my diet is healthier AND more enjoyable, and I feel better and more energetic than ever.

Kiera is an amazing listener and one of those rare people who immediately makes you feel comfortable opening up. I appreciate her wholistic approach and that she tailors her guidance to you as an individual, your goals, background, and lifestyle. She’s really made the confusing world of health/ wellness feel less stressful and easier to navigate.

Kiera was great! She’s super kind and patient. She didn’t try to rush the appointment and took the time to actually explain things in a way that made sense. I really appreciated her knowledge and expertise and she also called out where the science wasnt clear so that I could made informed decisions. Would highly recommend.
