  • positive review  I was introduced to Garrett and Tandem Nutrition through a friend that had great results. Working with Garrett, or Coach g, was the best decision of my life! I had previously struggled to stay consistent with my diet as I fell victim to many so called "fad diets." Coach g helped me realize that I could still enjoy food and be healthy at the same time! I saw great results and lost, and kept off, around 20 pounds during our time together. He truly cares about each one of his clients and Tandem has a great team of dedicated and compassionate individuals. If you are ready to make sustainable life changes look no further than Tandem!

    positive review  So many great things to say about the Tandem Team! I had the privilege of working with Jason Barnes as my coach and he was the most helpful, positive, and motivating Coach I could have had. Garrett and Jason often offered words of encouragement and were always there to answer any questions I had. I started my journey with Tandem wanting to be a physique competitor, and over the course of my 11 week prep, the knowledge and information they shared with me was always science-backed, so I had a sense of comfort knowing I was doing the best I could for my body while on a prep. I loved having the support from not only Garrett and Jason, but the whole Tandem community, as multiple people would reach out to me regarding my progress! Another one of my favorite things Tandem Nutrition offers is community events, so you can tell they are invested in making the community a healthier, happier place. I love what you guys are doing, and keep up the great work!

  • positive review  I worked with Garrett for over a year through multiple fat loss and maintenance phases, and I cannot say enough good things about my experience! He was so flexible and supportive, and was always there to answer my questions, no matter how small or silly they seemed. Not only did I get amazing results, both aesthetic and performance-based, but he really helped me change the way I think about food and dieting. I was still able to enjoy the important things in my life while still losing fat and gaining strength. He kept me accountable, and I felt like he was truly invested in my success, celebrating my wins and supporting me through the not-so-great days. Working with Garrett was an honor and a pleasure, and I would recommend him without any hesitation!

    positive review  The Tandem Nutrition team absolutely knows what they're talking about! They're full of useful information, and I love that they preach eating the foods you love while becoming healthier. I don't at all understand Coach g's obsession with pancakes ?, but I guess I can let that slide ? #teamwaffles ? If you're looking for coaches who are willing to work with you, who are kind and supportive, but who are also willing to tell you the truth when you need to hear it, these are the folks for you.

    Garrett understands food ingredients in a way that most do not. He translates this to common sense small changes in daily food choices that are easy to adopt. As a client of his for over a year, I highly recommend his services.

    positive review  Garrett is very knowledgeable and knows how to individualize your program so it works for you. He’s very motivating and makes this an easy process/transition. I’m a personal trainer, but my nutrition was lacking and what I was doing wasn’t working. Garrett helped me get my nutrition back on track. I highly recommend him!

  • Garrett has been so helpful. Mentally I know how to eat to be healthy, but having G walk with me has been wonderful. He has listened to my thoughts on calories with my age and physical abilities and adjusted where it was needed. The way he coaches and his encouragement speaks to me and motivates me to want to be better each day! He is a true blessing in many ways.

    positive review  I have been working with Coach Jason for a month now and I am beyond happy with my progress thus far!! I still have 12 weeks left of my program and I can’t wait to see the changes at the end of this! Tandem Nutrition takes the hard work out of eating healthy by providing you all the tools you need to be successful, you just have to be willing to make the changes to see results! Positive, encouraging, and super knowledgeable are just a few of the words I’d use to describe Jason and the Tandem team!

I have learned more about nutrition, balance, and how my body works than in the previous 33 years combined. I fully recommend the Tandem Team, regardless of your goals! I have zero desire for body competitions, but still got 100% focus towards my own goals of weight loss and energy gain. Thanks so much Team!

    Have you tried every diet only to fail? You name it I’ve tried it. I started working with Garrett in July. I had been working out 5 times a week faithfully. Only I was stuck. I had been trying to lose weight but this time I couldn’t. I was to the point of giving up. Garrett has changed my life! He is so knowledgeable, he is so responsive to all your questions. He truly gets involved and genuinely cares about you as an individual. I have been so successful since I met Garrett! He is amazing! Sometimes there are not enough words to describe how great of a person he is.

    positive review  I began following Garrett on Facebook because of the great information he posts, and after following his social media presence in the nutrition industry for a little while, I finally reached out to him directly. Garrett was immediately responsive despite not knowing anything about me. Ever since our initial interaction, Garrett continues to impress me with his passion, enthusiasm, and knowledge. He strives to help others grow, improve, and become their best self in many aspects of life, even beyond nutrition. Garrett carves time out of his busy schedule to help me grow my business in DC out of the kindness of his heart — truly selfless. I'm honored he sets time aside to help me develop. Garrett is thoughtful in his responses, his questions, and is incredibly motivating. I learn a ton from him every time we interact. Garrett genuinely cares for each and every one of his clients and works tirelessly to guide them and support their success. His extensive knowledge and education paired with his empathy, energy, work ethic, and upstanding character — it's a top-notch recipe for an amazing coach!

    Garrett is a true professional has a complete understanding of macros needed, physical conditioning needed and blood chemistry. He has helped me learn how to approach all three of these key factors to better my life. He is not intrusive but compassionate about his approach. Give him a try if your willing he can help. He has for me and I know others who have experianced the same.

His knowledge of nutrition and macro counting that he has shared with me has helped me make better food choices on a daily basis. I highly recommend Garret to anyone wanting to make a change in their body composition!

    negative review  I started my journey 3 months ago with Tandem Nutrition (working with coach Kasey). In these past 3 months I have learned so much about myself, let alone how to lose fat. I honestly didn’t think I could lose fat and weight on my own. I started this journey at 183 lbs and today I weight in at 168.4. I’m extremely proud of myself for the goals I have accomplished during this time. I am extremely grateful for Tandem Nutrition. Coach Kasey is an amazing person and taught me a lot. Thank you!

  • positive review  hey everyone! Garrett is the best health coach I've ever encountered. he actually cares about you and your goals. he's not just someone that throws facts at you that you don't understand then doesn't help you at all. He helps and a lot. I've lost so much weight under his guidance and on top of that I've gained A LOT of muscle so most of weight loss is pure fat! I was dieting long before I met him I did lose 12 lbs however I was not happy! Dieting sucks. now I don't feel like I'm dieting but rather feel GREAT and losing body fat is a plus while feeling good! 10000000000000% recommended!!

    I've tried everything....starving myself, going to the gym daily, low carb, low fat, high protein, etc., etc., etc. I would get so frustrated after trying these "fads" that I would become demotivated within 2 weeks and give up. I got to a point where my clothes didn't fit, I was tired and didn't feel healthy. Finally, I was introduced to Tandem Nutrition and this has been life changing. Garrett taught me the basic concepts of Macros and what good nutrition looks like. He has debunked myths that I have followed for years that were never successful. Finally, I have a nutrition plan that I can follow with normal, everyday food and am now much more knowledgable of what a good diet looks like. Garrett holds you accountable but also recognizes that life can get in the way and is your biggest cheerleader. He is reachable 24/7, always pleasant and supportive. Thank you Garrett for your expertise and support...you have been a blessing to me.

    If you’re looking for someone to assist you in reaching your weight loss goal, look no further. From the beginning until now Garrett has been fantastic: professional, incredibly knowledgeable, courteous, thorough, understanding and my biggest cheerleader. Garrett is easy to communicate with and responds to my questions and concerns in a great timeframe. I had lost a considerable amount of weight a few years back and due to the stress of a natural disaster I had gained back nearly 30 lbs. I was stuck and couldn’t figure out what to do to get motivated. I reached out to Garrett and within a brief period of time he got me back on the path. He listened to me, asked me all the right questions and formulated a plan to help me lose weight and work towards maintaining good overall health. So far I’ve lost a little over 10lbs at a safe and reasonably comfortable pace. I’m still working on the last 16lbs and do so with complete confidence with Garrett as my Coach! �����

  • I was fed up with gaining weight, pants that felt too tight, not feeling comfortable/confident in my clothes, not sleeping well, and was struggling with energy. I knew something needed to change. I had tried other diet programs in the past, but had trouble sticking with it, or would lose weight just to have it creep back up again. I saw that a high school classmate of mine had success working with Garrett and checked it out. This is the best thing I could have ever done! I'm just a normal gal - married, work full-time, mom of two - with all the normal stresses we all have. Garrett helped me work a plan he put together for me after getting to know what my day-to-day life was like and the goals I wanted to achieve. It was different than anything I had ever tried before...and it worked!! I'm down 2 dress sizes, 20 pounds, and 20 inches in 6 mos!! I have a lot more energy, I'm sleeping better, and I'm enjoying how I look in clothes. And, the great thing is...you get to eat normal food (gasp)! I was able to do this with the only exercise my crazy life could accommodate at this time...walking! No crazy stuff here, folks. Just good, straight-forward advice that ANYONE can follow. He is very encouraging, has great tools to help you along the way, and is a great motivator. I highly recommend if you're ready for a change to work with Garrett!

    Working with Garrett has been a rewarding experience and a great investment for my health. Learning more about nutrition and having someone hold me accountable was something I needed to help get me in the right direction. He always answered my questions and was very prompt at getting back to me. I have a very busy life that I enjoy, which makes nutrition go out the window at times. Working with Garrett I learned how to look at some foods differently and find alteratives to what I was already doing. It was a great learning experience and I would recommend him to anyone looking to take the next step on their fitness/health journey. Great job Garrett!!

    I have been working with Garrett for about 8 weeks now. I'm beyond blown away with his attention to detail. I have done every yo yo diet in the world and for the first time in quite some time I'm eating foods I enjoy AND losing weight. In the time we've spent together I'm down 14 overall body inches and several pounds. I've hit PRs with lifts I've trained for years on and overall I'm thrilled. I highly recommend Garrett to anyone wanting someone who can program macros and workouts as well as having an awesome motivator in your corner.

    positive review  What if I told you, there is a trainer who is breaking the mold of diet and training? What if I told you, you could eat the foods you love and still have a plan to lose fat and keep it off? Then, Tandem Nutrition and Coach g (Garrett Serd) are the answer to your struggles. Don’t be like me, don’t waste your time stalking this man on various social media to see what he’s saying and what others are saying about him (I followed him on IG and FB for nearly two years). Without a doubt I’d recommend coach g to anyone looking for nutrition and training guidance. But you get so much more than just that, he’s a great motivator, he’s always positive, he’s a spiritual and religious guide as well (for those who want it, he’s never pushing anything on anyone), think of coach g as a life coach. It’s a total package, body, soul and mind!! Coach g truly does care about his clients, he’s checked on me more than I have, he has always kept the lines of communication open. I have dealt with other online coaches in the past who barely cared if I even checked in and were too busy with other things. Coach g brings his focus, positivity and dedication to each client. His portfolio of clients is the real testament to his success. His training and nutrition plan approach is amazing and hits all your needs, but I’d recommend you come with questions and that’s where you will see why he’s the best. He will listen to you concerns, he will make changes where and when needed, best of all you will notice how humble he is in his method. He will never push an agenda, he wants you to be happy and have the tools to be successful in attaining your goals. Coach g is truly in tandem with your success and goals. Its not a one size fits all approach at all, yeah there might be similarities in the approach but each one of his clients has their own customized training and nutrition plan, which I love. He will make himself available when you need him, he offers so much of his time and knowledge in pursuit of dispelling the many myths around training and nutrition. Just follow him on IG or FB, it’s a free education on those topics, imagine what you’d get if you hired him as your coach.

Jason and Garrett in particular can help you reach any goal you have in mind and work with you to bounce back if you struggle or even fail. They treat you like family because when you join Tandem you ARE family?
