Theresa Yelek – Sasquatch Investigator in Northern Colorado

Bigfoot Researcher Theresa YelekI grew up in Prince Fredrick, Maryland until I was 8 years old. Then I was moved out to Colorado and fell in love with the mountains. I have been going to the mountains since I was a very young kid.

I am married to a wonderful man and we share two beautiful sons. My husband introduced Bigfoot into my life about 20 years ago. But, I did not really open up my eyes to Bigfoot until 2009.

I am a 100% believer and yes I have had the privilege to see one. My husband and I share
this passion together and this brings something very special into our marriage.

I love hiking, fishing, camping and just being in the outdoors. I also really enjoy photography and Bald Eagles.

Here’s some of my Bigfoot research articles:
