ISSA Certified Nutritionist(note that despite the name, this certification alone does not allow the use of the term “Certified Nutritionist” in many states, including New York)
Only a person certified by the State Education Department may use the titles certified dietitian-nutritionist, certified dietitian, or certified nutritionist in New York.
Certification is not required to perform nutritional counseling in New York, but only individuals certified by the New York State Education Department may use the certified dietitian/nutritionist titles.
The initials used in connection with a licensed physical therapist’s name are “P.T.” Only the use of the abbreviation “P.T.” is protected in law, which means that only a licensed physical therapist can use these initials. Although an individual can include the academic degree in one’s signature, these designations are neither recognized nor protected by Education Law or the Rules of the Regents. You may find that there are other individuals using initials that may look like they are a physical therapist. CPT, for example, is used by certified personal trainers, but they are not licensed professionals and they are not physical therapists.
