Michael Devon, NASM-CPT

* San Antonio location

Hello, I am Michael Devon and am a native of San Antonio. I started my path toward health and wellness with my studies in nursing. After completing my first year of nursing school I received my LVN certification. As I treated patients in nursing school, I soon realized that disease prevention was the key to ultimate wellness! Why focus on treating a sickness when we could prevent the illness in the first place? This led me to surround myself with those who shared my passion for dietary health and wellness. I’m nearing the completion of my Bachelor’s Degree from the University of Texas San Antonio…and as a supplement to my own research, I’ve completed additional courses outside of my major to absorb as much information on the topics of nutrition, exercise, and alternative health. My passion for fitness fueled me to receive my Certified Personal Trainer’s certification from The National Academy of Sports Medicine. I now have an integrative approach to health and thus stress the importance of proper nutrition and individualized exercise programs for all of my clients. Through nutritional education, people will realize how eating the right foods can be as beneficial as medicine. Ultimately, this will lead individuals down the path of long term health and prosperous living.

Ciara FloydHello. My name is Ciara Floyd. I have a passion for helping people improve their lives through exercise and nutrition. I have a Master’s of Science Degree in Exercise Physiology from The University of North Carolina at Greensboro. While pursuing my Master’s Degree I spent time training intercollegiate athletes. I have been coaching and training athletes for 10 years as a gymnastics coach, physical education teacher, and sports performance coach. I was also a collegiate track athlete for four years at Samford University. The majority of my career has been focused on athletic improvement. In the last few years I have spent more time working with a non-athlete population. I have found so much satisfaction in helping people meet their individual goals to live a healthier more fulfilling lifestyle through exercise and improvements in nutrition. I look forward to continuing this work and helping people meet their goals.

Kimberly Black, 200YT

* San Antonio location

I’m Kimberly Black and my passion for health and fitness has spanned throughout my entire life. I have always led an active lifestyle, playing sports, as well as coaching and refereeing in high school. This passion led me to obtain my Bachelor’s of Science Degree in Kinesiology with a specialization in Exercise Science from UTSA. While in college, I began to attend yoga classes and have been studying yoga ever since for the past 8 years now. Upon completion of my Bachelor’s, I decided I wanted to study yoga more in depth and I began studying to become a 200 hour registered yoga teacher. During my study I was able to link my passion for health and fitness with the yoga aspects of mind, body, and spirit. My love for yoga has grown indefinitely and I thoroughly enjoy spreading the message of self-acceptance, mindfulness, and self-awareness.

Michelle Baglio, RD

* San Antonio location

Michelle Baglio

I’m Michelle, and my nutrition started at a young age by learning to prepare delicious healthy foods at home with my mother. That skill developed into a passion for nutrition and a Bachelor of Science degree in dietetics from Indiana University of Pennsylvania. I then completed my dietetic internship with the South Carolina Department of Health and Environmental Control. I’ve been a Registered Dietitian (RD) for 16 years and I am currently working on a master’s degree in nutrition with Central Michigan University. I’m constantly in pursuit of additional continuing education, because nutrition is an evolving science. Throughout my career, I have been fortunate to live in all regions of the country as my husband has made a career in the U.S. Army. Through our travel, I have experienced multiple cultures, styles of eating, and food habits. My career as an RD is well versed as I have experience in research, acute care, bariatric surgery, and weight management. The experience I gained in all of these areas have enriched my career and enabled me to provide exceptional service and support to the individuals with whom I work.

A decade of my career has been focused on helping individuals achieve greater health and wellness through nutritional assessment and counseling. My philosophy is that every person is an individual with unique needs whether it is to lose weight or to manage a chronic disease such as diabetes (or both). Over the past few years, my focus has turned to integrative and functional nutrition. This approach is individualized to each person and evaluates all body systems using a combination of physical symptoms and laboratory tests to identify factors that may contribute to health or weight concerns and then providing the tools and support needed to meet their health and wellness goals. I am a member of the Academy of Nutrition and Dietetics and belong to several dietetic practice groups including Dietitians in Integrative and Functional Medicine, Weight Management, and Women’s Health. I’m excited to be a part of JKFITNESS and look forward to helping you with your nutritional needs.
