What people are saying...

I've been working with Alissa for over a year. My health has improved greatly with her advice and direction. Alissa is always supportive and gentle, but she's strict in a nice way whenever I need the push to look after myself. Alissa's approach combines using science data and listening to/observing signs of my body, striking a balance between the both. All in all, I can confidently say that my health has improved greatly since I started working with Alissa. I feel so much more confident with myself now. Thank you.

JWClient

Simple, straightforward advice from a lady that truly knows what she’s talking about. I haven’t had to deal with my insomnia for weeks by following the advice from Alissa.

YKClient

I initially contacted Alissa to discuss my issue with being unable to lose weight. Alissa asked me to fill out a very comprehensive questionnaire and on our first session she asked additional questions about my lifestyle etc. She also requested I do some blood tests which were very eye-opening. Alissa created a protocol tailored to help me overcome my issues and after a few weeks of following her guidance, I felt much better. Alissa also recommended supplements to support my immune system and optimize levels of vitamins and minerals to increase my energy levels. I’m very impressed with how amazing she was at reading and understanding my body and how she tailored the treatment to meet my needs. Working with Alissa is one of the best decisions I have made. I am now armed with the knowledge to better manage my health and overall, I have never felt better.

MKClient

I can't thank Alissa enough for the help she's given me with improving my diet. I sought her advice to change my diet to help with anxiety and PMS, as well as to live a healthier lifestyle. Thanks to her recommendations, I feel fitter and healthier than ever. I haven't missed the foods she advised reducing, as the alternatives have been so delicious. My skin is clearer, I can run further and the anxiety is now at a much more manageable level. Thanks so much Alissa!

MJClient

Alissa has helped immensely with my inflammation and arthritis symptoms. She is extremely knowledgeable on food and nutrition for healing. Her excellent advice and education has helped me manage the condition which has improved hugely since I first saw her. Highly recommended

JPClient

I highly recommend Alissa, she really cares about her clients and will leave no stone unturned to achieve results.

AZClient

I'm am beyond thankful to have found Alissa. I went to see her after trying to manage my health problems with conventional medicine for over a year without much success. I received very comprehensive advice from Alissa. She included physical, psychological, and environmental factors in the diagnostic process and created a personal treatment plan, which was adjusted according to symptoms. I‘m much improved after a very short time frame (6 months). Her guidance, supplements, and support have revitalized my mind and body, I have loads more energy and am equipped with a far better understanding of my body and triggers.
