  • Are you wanting to lose weight or gain weight?
  • Are you looking to optimize your food choices to help prevent disease or manage a chronic condition?
  • Do you need some guidance with a certain type of eating plan you are following including: gluten-free, meat free, low carbohydrate, or other?

Please note: When requesting a nutrition consultation, depending on what type of nutrition consultation wants and needs you have, you may be connected with one of our additional staff members trained in nutrition, who hold certifications/certificates in nutrition but are not RDN's. These staff include: Keri Johnson, and Kerry Howell (see staff bios). Appointments with them can also be made by emailing
