Reviews From Clients
Posted on Google Sydney PanikkarTrustindex verifies that the original source of the review is Google. Jaqueline is the kindest, most supportive nutritionist I’ve ever worked with. She has been sensitive to my history of disordered eating/body image struggles and guided me to a much healthier relationship with food. She had no qualms about accommodating my veganism and clocked the signs of my insulin resistance right away (I had no idea). I am so grateful that I had her to support as I went through the process of PMOS diagnosis. She’s conscious of the cost of supplements/affordability and helps me adjust things when I need it. I really cannot cover all the amazing ways she has impacted my life in one review!Posted on Google Markus LotzTrustindex verifies that the original source of the review is Google.

The transformation I’ve experienced with her has been more than just physical! I’ve mentally come a long way from a place of disordered eating and that’s thanks to her support and guidance.
