Q: How did you get started on FATCO?

I grew up on the East Coast and graduated from college with a degree in Mechanical Engineering in 2005. Soon after I graduated, I moved out to San Diego, where I quickly got a job in Automotive Manufacturing (at a company called Autosplice).

I worked there for 10 years. I enjoyed my job and was making really good money (maybe about $90K when I left) but I never felt like I was recognized or used to my full potential. I was a female engineer who worked at a company where all of the executives were men. I recognized that there wasn’t much potential for upward growth, so I started contemplating my next move.

I first read It Starts With Food back in 2012 and did my first "Whole30" that year. Eating Paleo Changed My Life! I felt better and had a ton more energy! As I started paying more attention to the foods that I was putting into my body, I also started paying a lot more attention to the products that I was using ON my skin. I started taking a deeper dive into the products I was using on a daily basis (shampoo, body wash, makeup, etc) and realized that many of these products were full of toxic chemicals and dangerous ingredients. So, I started making many of my own personal care products.

I started researching and learning a lot about the topical benefits of tallow from grass-fed cows. Through the Weston A Price Foundation website, I learned that Tallow from grass-fed, pasture-raised animals is very high in vitamins A, D, K, and E, all of which are very important for skin health.

Tallow is also incredibly nutrient-dense and healing for skin conditions like Eczema, Psoriasis, Keratosis Pilaris and Dermatitis. So, I slowly started integrating more animal fats into my recipes, and the products I was making were amazing!

For a long time, Fats and Oils have gotten a REALLY bad rap. But more recently, many people in the medical community are beginning to recognize the health benefits of integrating healthy fats into your diet. Things like coconut oil, avocados, and grass-fed butter are becoming more and more acceptable, and are even being touted as "good for you"!

We use similar vegetable-based fats (shea butter, coconut oil, cocoa butter) in our products, but we also integrate healthy animal fats into our formulations, too! Fats and Oils are so incredibly healing for your skin, and can actually aid your skin in its own ability to balance itself! Fats and oils are truly remarkable for your skin!

Surround yourself with people who believe in you and believe in what you are doing. If the people in your life don't believe in what you're doing as much as you do, it will eventually become toxic and stifling to your success.

I am not an esthetician. I do not have a deep-rooted background in cosmetics or the skincare industry. All I knew was that I was making some really amazing skincare products in my kitchen and that other people would benefit from them! And I also knew that no one else was touting their use of animal fats as a key ingredient. But I did know that those in the paleo community would be very receptive to these types of products!

So, I started to do some research into the rules & regulations within the personal care category. Lucky for me (at the time), there were very limited regulations around what was required to legally start producing skincare products, or around what ingredients were allowed and which were not. While this was beneficial for me, in the end, I believe that it’s extremely disappointing for the general consumer. This means that big businesses can use whatever ingredients they want (good or bad) and never have to run it by a governing body. Personally, this scares the crap out of me, as a consumer.

Unfortunately, many commercially available personal-care products on the market today are full of toxins and chemicals! This makes it very difficult for the consumer to know what's "good" and what's "bad". Many products contain ingredients that can affect our fertility, can disrupt our hormones, and that can cause cancer!

Many companies claim that these chemicals and toxins are found in such small quantities that they will never really "cause consumer harm." But considering that the average woman uses 12 skincare products per day and that these products are used repeatedly every single day, this can result in our bodies being bombarded by chemicals! And this is from products that we believe are going to be helping us!

So for a long time, I wanted to start a business, but couldn't think of anything that I was passionate enough about to make it into a business. But as I began to learn more about the dangers of conventional skincare products, along with the recent popularity of “healthy fats”, I thought that I might be onto something.

Eventually, a friend of mine gave me the push I needed to start FATCO! She convinced me that these products I was making were unlike anything she had used and that there really was nothing else like it on the market! And she was right...these products are truly one of a kind, even 6 years later!!

The "Nose to Tail" philosophy is one that I personally believe in deeply, and it has become a key pillar in our brand ethos! You can even see our dedication to this philosophy in our logo! “Nose to Tail” is the idea of using every single piece of the animal, and not letting any of it go to waste. This means using the bones for making broth, eating the nutrient-dense organ meats, and using the fat to create some pretty kick-a$$ skincare products!


The meat industry is one which is NOT going away anytime soon (almost everyone I know personally eats meat) so we believe in supporting the ranchers who are doing it right and not supporting the ranchers who are doing it wrong. This is why we're so picky about who we source our tallow from. We only use the highest quality tallow that comes from grass-fed, pasture-raised, happy cows! Our current primary source for tallow is based out of Colorado, and they source their fat from 25 US-based, family-owned farms.
