How Nutrition Counseling Works

I currently hold a certification as a Specialist in Performance Nutrition (SPN). Before I started working with Katie and Esther, I was doing all the Colorado nutrition consultations with my clients. I was able to help my clients with their nutrition programs. However, as I became busier, my time was limited because I needed to focus on my clients’ exercise programs. They were not getting the detailed attention that they needed to help them succeed quickly.

Katie, Esther and I have the same philosophies when it comes to exercise, nutrition and health. We educate our clients that an all or nothing approach will never work. You can’t exercise all the time and hope to lose weight and be healthy. On the flip side of that, you can’t try to eat healthy all the time and hope to lose weight and be healthy. By incorporating a proven exercise and nutrition program together, you will get the best possible results – better than just focusing on one of these disciplines.

Most personal trainers in Northern Colorado will give you nutrition advice in order to help you with your goals. However, they are not as educated as a registered dietitian. This is why I have partnered with Katie and Esther to give you the best possible plan to help you with your health and fitness goals. Here are their bios:

Katie Kissane, MS, RD, CSSD

As a registered dietitian nutritionist and lifestyle coach, I specialize in simplifying complex nutrition science to help clients achieve their goals while enjoying delicious food. With expertise in sports nutrition, weight loss, and disease prevention, I work with individuals of all ages and backgrounds. My personal journey, including struggles with health during college athletics and my mother’s diagnosis with Celiac disease, ignited my passion for nutrition. I firmly believe in the transformative power of nutrition and exercise, advocating for lifelong lifestyle changes over temporary diets. Let’s collaborate to create a tailored nutrition plan that fits seamlessly into your busy life. 

I’m an RD/RDN passionate about helping northern Colorado residents shed pounds, boost energy, and overcome disease. With certification as a First Line Therapy (FLT) provider, I specialize in wellness coaching and weight loss. Hundreds of patients have successfully achieved weight loss and improved health under my guidance. I’m all about enjoying good food and wine with friends, and I believe healthy eating can be affordable and simple. By billing through health insurance, I make nutrition therapy accessible to all. Partnering with Dennis, I advocate for a holistic approach to health, combining exercise and nutrition for optimal results. Let’s embark on this journey together to transform your health and lifestyle with real food and sustainable changes.

Client Testimonials

Dennis is the best personal trainer ever...truly! After a few workouts, I was doing things I didn't even know I was capable of! I will never train with anyone else. If you're looking for someone to take your money and go easy on you, Dennis is NOT your guy. However, if you want a serious trainer that will work you to your fullest potential and help you meet your goals, give Dennis a call. Not only have I lost weight as a result of his workouts, but, my flat tummy is back! Woohoo! Thank you Core Fitness!!!

At the age of 23, I was diagnosed with POTS (postural orthostatic tachycardia syndrome). Which meant that any form of physical exercise would prompt dizziness and the occasional fainting. Whenever I stood up too fast or got out of bed, I'd get lightheaded and dizzy. As a very active, young individual, not being able to hike, play sports with friends, or make simple positional changes made life very frustrating. Most importantly, for my dream career I needed to get SCUBA certified, but was unable to do so with my condition.

My doctor recommended that I seek out someone to help me with consistent and graduated physical activity to strengthen my cardiovascular system. That's how I came across Dennis Blair and he does a great job creating a plan to help me progress with my physical activity. He is exceedingly thorough and thoughtful when it comes to my specialized training plans. We went from simple exercises on the ground to standing and jumping! I've been working with Dennis for roughly 1 year now and, WOW, what a difference it has made. Dizzy spells and lightheadedness are now infrequent and I've been able to get back into rock climbing, riding my bike, moderate hiking, and get out of bed in the morning. Plus, I am so close to being cleared for SCUBA diving! I could never have gotten to this point without Dennis.

I am so grateful for Dennis and his dedication to helping me get back to the active lifestyle I once had lived and working towards my dream job.

Thank you, Dennis!!

At the ripe old age of 64, I knew I needed to do something to ward off the effects of being undisciplined with my diet and physical activity most of my life. With a strong recommendation from a friend who had had incredible results working with Dennis for a couple years, I knew it was an opportunity I could not turn down:) Now after two years with Dennis as my personal trainer coaching me through 2 workouts per week, I can testify I have not only lost weight, but, more importantly, I am stronger in all areas of my body! The strengthening has allowed me to do things I could not do before (i.e. walking all over New York City). Dennis was sensitive to where I was when I started with him, and, he designed a program personalized to what I needed and wanted. He is encouraging, professional and gets results because he expects results!
