To answer your question the answer is yes. Having a RD to refer to is always the best way of approaching dietary issues with your clients. The best way to figure out which one to chose from, is to do some research online and find those who match your philosophy and needs and then meet with them to see who you would like to work with. Check their credentials, work and education history as well as references (if available). This kind of relationship can work both ways. I hope this helps.
