I highly recommend Cristina and her services. She will really take the time to get to know you and give you the attention and time you need to find a solution to your problem
G.M. A person living with Sjogren's
Working with Cristina helped me understand how to eat healthier with my rheumatoid arthritis.
She answered many of my questions that only someone with clinical training and lived experience could answer.
I was so fortunate to be in Cristina Montoya’s beta group for her incredible program.
This program had the perfect amount of information given in enough time to digest it, put it into practice, and form new healthy habits.
N.E. A person living with Lupus
The Low FODMAP Diet for Sjogren’s was the best presentation on something related to Sjogren's that I've ever attended. Practical, useful advice, rooted in science. You are an approachable and good presenter.
