About Sally

Writer. Speaker. Explainer.

Nutrition & Lifestyle Medicine and Complementary Health

Hello! I’m Sally

Nutrition copywriter, author, speaker, and perimenopause nutritionist.

My story

Nutritionists have a reputation for being pious, clean-living individuals, baking kamut muffins for fun.  I hate to disappoint you – I’m really not like that.

I was a terrible pescatarian in my teens and early twenties. Well, more of a ‘pastafarian’​ given I lived on pasta bake and cheese. My poor food choices led to zero energy, spots, raging pre-menstrual tension, bloating, crazy bowel habits…

But everything changed when I started working at Tullivers a fantastic health food store in York, UK. Here I began my journey into the world of nutrition, herbs, and positive lifestyle changes.

It was so rewarding helping customers that I decided to become a Nutritional Therapist. For more than a decade I ran a private clinic in York. I’m now a lifestyle medicine and nutrition copywriter, author, speaker, and perimenopause nutritionist.  I run workshops on a range of topics to improve employee wellbeing and work 1-1 with perimenopause clients.
