looking for nutritionist in Brookline

I was on this website (or a linked one) about 5-6 months
ago when we were trying to switch our very allergic puppy to adult food (with lots of complications) looking for someone near Boston who works on nutritional needs of dogs and found a listing for a woman in Brookline- I can no longer find this person on AVH or AHVMA directories- does anyone have an older listing (maybe she has moved or just didn't keep up her dues and got dropped from the list) or know of someone near Boston (we live in Somerville) who would be knowledgeable in trying to work out digestive problems/allergies which appear to be food related?

Thanks for any help that can be offered
