About Us

We create results based nutrition programs.

Dustin and I have collectively been in the health and fitness industry for over 18 years. My husband, Dustin, is the most gifted certified personal trainer you’ll ever find (bias alert!!), with a huge passion for seeing people transform their body, mind, and health. He’s also a fitness model and former All-American athlete, so he kind of knows what he’s talking about :). He also received a degree in Sports Marketing.

My (Leslie) academic background is actually in International Business and Spanish, and I’m also Precision Nutrition Certified. My love of nutrition, health, fitness, bio hacking, and all things non-toxic really took deep root when I met Dustin. We got on a crazy kick together to eliminate as much of the junk in our world as possible.

We then soon decided to open up a smoothie bar and conduct all of our nutrition coaching from our store and all of our fitness-related business out of our gym space. We made smoothies and coached clients at our store for about 3 years, but now we focus on our online and in-person coaching.

I also absolutely love making fantastic-tasting food and smoothie recipes, so we spend a good amount of time hanging out in the kitchen (hence our nutrition coaching company is called “Fit Body Kitchen”…Where we show people how to “Eat Clean. And Get Lean.)! 

It’s been an amazing journey of coaching wonderful clients and seeing them reach their goals of better health. Nothing excites me more than seeing our clients reach their goals and having their health and lives transformed. I love to encourage. I love to see the “light bulbs” come on. And I love to see our clients take ownership and get excited about continuing to grow in their knowledge and practice of health, fitness, and nutrition.

We both share a passion for being the biggest health geeks possible and learning how to improve our health on every level. We love sharing this passion with YOU!

Thank you for your support!

Dustin & Leslie

What our Clients say

  • I found my experience with Fit Body Kitchen to be an overall excellent experience! First, you won’t find nicer people to work with. They are focused on you and tailor the program to fit YOUR needs. Second, they are extremely knowledgeable. I have been interested in nutrition and exercise for most of my adult life and found some new tidbits and insights that were very helpful to my health journey. Third, the program works! I lost 7.5 inches in 30 days! I was already a size 4, so they helped me fine-tune my body inside and out. Fourth, the program is sustainable. I have incorporated the lifestyle changes into my daily life and plan to continue going forward. You can’t go wrong with Fit Body Kitchen, and I would not hesitate to use them again in the future!

  • I love working with Leslie and Dustin. With their help I was able to lose over 10 pounds and get off my acid reflux medication. They always have helpful and healthful tips for me and suggestions on foods to choose. I hope to keep working with them. It has been successful for me.

    — Kim S. —
  • I used to hate dieting until I found Fit Body Kitchen. I’ve lost 47lbs so far! Best of all I like the flexible dieting approach that Dustin and Leslie take that allows me to eat the foods I want  while still getting results! Thanks

  • I found Leslie & Dustin at Fit Body Kitchen when I was trying (to no avail!) to lose my last few pounds of baby weight. I have always considered myself healthy and work out regularly, but still could not drop those final 10 pounds. I was skeptical when I got started only because I thought I already knew how to eat “healthy”. Boy was I wrong! What I loved about working with Fit Body Kitchen was that it wasn’t just about being on a diet or losing weight, it was about making educated decisions about what you eat to nourish your body for the long term. I learned so much about the food choices I make on a daily basis & how I can make cleaner, healthier choices every day. During my program, Leslie bent over backwards to make herself available for any questions or help that I needed. She always encouraged me along the way with texts, calls & emails and kept me motivated to stick to my customized plan. And it didn’t hurt that the results came fast, too! By just implementing a few simple & healthy choices in my diet I was able to shed those final pounds & feel the best I’ve felt since before my pregnancy. I now feel educated & empowered to continue to make healthy choices to maintain the success that I’ve had with Fit Body Kitchen. Thanks Leslie & Dustin!

  • I’ve put on 12lbs of lean muscle mass. I’ve always wanted to “bulk up” but I when I tried on my own I just “fattened up” so I decided to get some help from Dustin and Leslie. I’m glad I did!

    — Tony F. —
  • I couldn’t be happier with the results I accomplished during my fit body challenge. We all know that eating healthy and working out are the basics to accomplishing your health goals but there’s so much more to it then that. During my 30 day challenge not only did I loose pounds and inches but I was informed about what I didn’t realize I was doing wrong. I’m still using all the knowledge they gave me and am continuing to learn from it as well. Leslie and Dustin welcomed me with open arms and I felt at ease with their guidance during every step. Can’t wait to do it again!

  • My sister and I have been working out with Dustin for a little over 2 years now. I can say that I am so much stronger then I ever thought I could be. He never ceases to amaze me on how many different workouts he can put together. We do something different each workout and he continues to shock my body with constantly changing things up. His knowledge on nutrition is endless. Any question we throw at him, he has the answer for. I love getting nutrition advice while I workout. Dustin and Leslie are both very educated in their business and are fun, kind people to be around. We enjoy every workout even though I leave exhausted.

    — Nicole E. —
  • Last November I decided I wanted to lose weight. I had tried in the past, but was unsuccessful. Since it was right before the holiday season, I had my doubts. But Leslie told me it was the best time to try. So I did. She made it so easy, and I lost 5 lbs between Thanksgiving and Christmas. Not only did I lose weight, but I lost 9 inches over my entire body. I highly recommend Fit Body Kitchen. Thanks, Leslie!

    — Melissa E. —
  • My sister and I have been working out together with Dustin for over two years now. He is skilled, thoughtful, sensible and a pleasure to work with and talk to. Dustin knows just how and when to encourage and when to push us. We are stronger and more flexible than we ever imagined we could be. Working out has become fun. Dustin & Leslie have also guided us in our nutrition to help us succeed, and it has been great.We give them our highest recommendation.
