Grissy Sime Mora

Adult Technical Instructor

Who are you? Where are you from? What do you do in the gym?

I’m Grissy, an adult instructor at Whetstone. I am originally from Santo Domingo, Dominican Republic but I’ve been living in the US since I was in elementary school!

When not a Whetstone, where might we find you?

Probably in the lab at CSU, I’m currently a PhD student in the Health and Exercise Science Department.👩🏽‍🔬

A favorite non-climbing activity?


What are you most stoked about these days?

Exploring Colorado! Since I moved at the end of last summer, I've been trying to go and explore as much as I can this summer.

How did you get involved with the gym?

I became a member as soon as I moved out here last August, then started working as an instructor in May.

Best thing about FoCo / NoCo:

All the fun events there are in Fort Collins!

What’s a low-key flex you can boast about?

I personally think I have the coolest birthday of the year… February 29th… aka THE leap day.

Favorite spot to recreate in:

When not in Colorado, the Catskills in NY are pretty rad.

How does climbing foster community?

Climbing creates an easy environment to meet new people and create lasting relationships.

Favorite climbing style?
