I found Clementine through a women’s business fair in Islington. Immediately, it was clear that Clementine is as understanding and committed as she is brilliant. Clementine guided me for the better part of a year through my health journey and I am very grateful for her!
Clem has equal amount of knowledge and compassion making it so easy to work with her and feel like you're in good hands. The face to face advice as well as all of the documents and handbooks she shares makes it really easy to absorb new information and feel like you can make progress. I really enjoyed my time with Clem and will 100% go back if I need any more support later down the line.
Clementine was a game changer in my postpartum journey. I was struggling to organize myself, not eating well, and starting to feel quite low about it. I was also desperate for expert guidance, feeling completely overwhelmed by social media. From our first session, I knew I was in good hands. Clementine's warmth and approachable nature made me feel comfortable right from the start. Not only is she incredibly knowledgeable, but she also has a genuine ability to connect with her clients, which made all the difference for me. She truly listened to me, and all her recommendations and tips came from a genuinely healthy place. She took the time to get to know me, understand my life, and address my true concerns. Her tips were completely tailored to my lifestyle and have made a radical impact holistically on my day-to-day life. She was also brilliant at ensuring I made progress without putting too much pressure on me. I really enjoyed our sessions—not only did we talk about nutrition, but we also discussed general well-being, which I really appreciated. Today, compared to when I first started, I feel less overwhelmed, more confident, and I know that some of her tips will stick with me for life.
I highly enjoyed my experience working with Clem. She made me feel comfortable, safe to explore my symptoms and looked after from start to finish. I feel a renewed sense of self, stronger in my gut, no symptoms and feeling lighter!
I worked with Clementine for a number of months and would not hesitate to recommend her. She is knowledgeable and insightful but her delivery of information is also empathetic and warm. She listened to my needs and how I wanted to work together and was always timely in her actions and follow ups.
I can't thank Clem enough for all of her help! After struggling with digestive discomfort for a long time, among other symptoms, Clem listened to my concerns and made a plan of action best suited to me. Within just a few weeks, I started noticing a huge improvement! My stomach issues have significantly decreased, and I feel so much better overall. She took the time to explain everything in detail and was always available to answer my questions, which made me feel supported every step of the way. I highly recommend Clem to anyone! Her expertise, kindness, and commitment to helping me feel better have truly made a difference in my life!
Clementine helped me during my first pregnancy adjusting my nutrition. I wanted to fuel myself adequately throughout the different trimesters both for me and my babies’ needs. She provided me with amazing advice and recipes at each stages of the pregnancy so much so I didn’t need to supplement. Blood tests showed that I didn't have any deficiencies, my energy levels were good as was my sleep. I was able to maintain an active pregnancy and deliver healthy baby (8lbs) on my due date. I truly believe that having had the correct prescribed diet, incorporating all the necessary nutritional values contributed to these positive factors. She also helped me with post natal meal options in the weeks following the birth. I would definitely seek her advice again if I had another pregnancy.
