Doug Davis - Founder/Owner

I have been looking at heart rate data for almost 30 years, while doing triathlons and cycling. Starting with Cooper’s AEROBICS and using his system of points, I examined and interpreted my data, as a method to measure physical activity and plan my workouts.

My first experience with a bicycle computer that showed heart rate, was a Pacer 2000. I was watching it intently while going down a hill when my recently married wife yelled at me to "Watch Out!" as a truck came around a curve toward me.

I’ve always been interested in cutting edge technology, especially as it relates to health and fitness. I have been using power sensors for 17 years, comparing power to heart rate. About 30 years ago, I started a gymnastics equipment business, Tumbl Trak, which has done very well, from which I have recently retired.

Now, my goals are to continue setting personal records for Watts to Heart Rate Ratio, eventually for a period of one to two hours, indoors. While pedaling, I harvest my energy, filling battery after battery!

My ultimate goal is to connect group and individual fitness apps, and to integrate this data with data from green machines that produce power.

Jody Avery - Business Development

I have two teenage boys that keep me active. I love soccer and still coach when I can, but if the sun is out you might be likely to find me camping on the beach somewhere enjoying some of the sunshine we don’t get in liquid form.

I was raised in the beautiful Pacific Northwest, where you learn two great lessons in life. First, how much there is to do outside in this wonderful part of the world. Second, how to build an immunity to rain! Growing up, it was easy to take advantage of outside activities with all that’s around here. I was always busy cycling, hiking, running, or swimming. I was actively involved in sports all year around for as long as I could remember. I had passion for playing that I didn’t know could turn into a career!

After ten years of being a jack of all trades in the construction industry, I decided to follow my passion and move from small town Port Townsend across the water to Seattle and launch myself into fitness as a career. I began training clients and was quickly promoted to General Manager where I had a successful 11-year career running health clubs and promoting fitness. I enjoyed a lot about the health and fitness industry and getting the opportunity to work around like minded people. Putting on fun events like Biggest Loser and Body Transformation contests, I spent my time and energy educating and motivating people to change their lives.

Although I loved working in the health club industry, I felt a strong desire to be closer to my boys and explore other career avenues that still involved health and fitness. Meeting the founder of TumblTrak and Fitness in a Heartbeat, Doug Davis, might have seemed like an accident two and a half years ago, but it has launched us into a great adventure creating a business fueled by passion for combining fitness education and cutting edge technology for all ages that would become the Heart Tech Plus platform.

Anthony Ciak - Executive Director

I started my career at the Boys and Girls Club helpings kids realize their potential. It unlocked what I had working with kids and identifying what they didn’t know they were capable of versus what I knew they could do.

This love for potential bled over into my excitement for fitness and health. In my own early career, I found, working with Jody, that there was amazing potential unlocking what people didn’t think they were capable of. I quickly found that the excitement we had for health and fitness was infectious and something we could share with others. It didn’t just need to be through our passion, but it could also be through our love for business!

I went back to college for business, graduated, and worked with a startup for two years in Seattle that required that same sort of love, passion and perseverance. I learned from it and gravitated back towards helping people through health and fitness and haven’t looked back!

Heart Tech Plus represents so much of what I love. Fitness. Health. Wellness. Awesomeness. I mean… shameless plug for the crazy amount of joy I get from spending time with my girlfriend, Jen, and our dogs Atlas and Sky. Of course ;) But seriously, thank you from the Heart Tech Plus team for the opportunity to transform yours, and the people you love, lives!

Kimberly Bushy - Office Administration

I have a bit of a unique resume. After graduating with a Bachelor’s Degree in criminal justice I decided I needed a little adventure in my life. I signed up as a volunteer with a non profit organization to help organize and lead tour groups through Asia doing humanitarian projects. I worked with them for about 4 years, and got the amazing opportunity to travel to remote villages, experience different cultures, and help people with enormous needs. I was always tasked with the “boring” job of organizing schedules, keeping track of passports, booking hotels, and keeping track of the money. It was during this time that I discovered I really enjoy working in administration.

I met and married my husband while working with this non profit, and shortly after we were married, we moved to Africa for a year to work in a poor township.

I have always had a gift for administration – and that is where I really thrive. After being a stay-at-home mom for several years, I jumped at the opportunity to join the amazing Heart Tech Plus team as their Administration coordinator. I am super excited about what this product can do, and can’t wait to see how it changes the lives of those who use it!

Bethany Friedrich - Education and Outreach

I have been a sports and fitness junkie since I was a young girl, as I happily spent my childhood stealing bases and diving after loose balls. Because the opportunity to play team sports does not present itself as often as an adult, it is now more likely to find me road cycling, backpacking, snowboarding or mountain biking with my husband, Adam, and our dog, Penny.

I graduated from Western Washington University with a bachelor’s degree in Therapeutic Recreation and Environmental Education. For the past five years I have worked as a certified therapeutic recreation specialist, making it my life’s work to get all kids moving, recreating and enjoying the out of doors. My personal interest lies in kicking down barriers that keep children with and without special needs from having the opportunity to run, jump, climb and play.

My favorite thing about the Heart Tech Plus system is watching how children engage and respond to it. To witness their curiosity and motivation after being able to peek inside their bodies and see their hearts working is definitely something special.

As an Action Based Learning Certified Trainer, I dream of the day that children will have more opportunities to move and play and learning will be done, in part, through movement and experiential education. I also dream of gluten free/dairy free desserts, u-cut flower farms, and learning to sail, but those things are less relevant so we will conclude here.

Rich Butterworth, M.Ed - Ambassador

A New England native and serious Boston sports fan, I am surprised and pleased to officially be part of the Seattle-based Heart Tech Plus team! My entire teaching career was spent in the Hamilton-Wenham Regional School District, where I taught Physical Education at both the Elementary and Middle school levels, and was also the Intramural Director. In addition, I coached baseball and basketball at the high school, where I had the pleasure of coaching my sons, both of whom went on to play college basketball. My daughter’s early and enduring love of animals led her to a career as a veterinarian. I went ‘back to college’ with my kids, and earned a Masters of Education in Technology degree. Dedicated to finding avenues of funding to bring my ideas to fruition, I was involved in the application process and the awarding of a Lighthouse Grant to implement technology in Hamilton-Wenham’s K-12 physical education program. I was the lead teacher in the district-wide effort funded from this Carol M. White Pep Grant award.

With this training and experience behind me, I have dedicated the balance of my professional career to the implementation of technology into all aspects of physical education programs nationwide, traveling throughout the country working as a technology consultant. Most of my extensive experience has been working with PEP Grants as both a Data Collection Specialist and Assistant Program Director. I also worked for eight months in Florida for the Polk County School District as a Teacher Resource Specialist for their PEP Grant. In education, I believe that if it is relevant and important, there are ways to find the necessary funding to support technology projects and program needs. My real passion is Heart Rate Technology and I can honestly say that I have been on a quest to find the best heart rate system for students and teachers, and Heart Tech Plus is the one.

Chris Mekelburg, Ed. D. - Ambassador

Dr. Chris Mekelburg Ed. D. – Rockville Center School District, Long Island, NY
As an elementary physical education teacher for the past seven years, I have had a unique journey which has led me to best practice in teaching in the public school setting. Since the beginning of my professional career I have written and administered a 1.4 million dollar federal PEP grant which has transformed the districts PE department. This opportunity provided me the ability to re-write the districts PE plan and seamlessly integrate technology into every class and teaching space.

The use of heart rate in physical education is the only way for an educator to objectively assess the effort and health of their students while participating in class. Concurrently this technology should be utilized to drive the decision making process as a research based approach to education. This technology allows for the seamless and objective evaluation of students, physical education teachers and directors of physical education programs. This technology has now reached the level where affordability and usability have met a balancing point and every district and teacher has an opportunity to change their program.

As a doctoral candidate in Education Leadership I have been able to mesh theory and practice on a daily basis inside the gymnasium walls. The use of data to direct program funding, continuation and relevance has been at the forefront of positive change in my district. My expertise lies in the incorporation of 21st century skill and technology into the Physical Education pedagogy.

Ross Chakrian - Ambassador

Hello everyone! I am extremely excited to be a part of the Heart Tech Plus Brand Ambassador team! Currently, I am one of the elementary physical education teachers at Waverly Elementary School in Ellicott City, Maryland, where I have been teaching for the past 7 years. I strive to give my students the best possible learning experience in my class on a daily basis and I hope to one day become a state, regional or national physical education teacher of the year!

I am passionate about quality, purposeful physical education. My belief as a physical educator is that I must practice what I preach and on any given day after school, you can find me running sprints or working out at the gym. On the weekends I like to get outside and enjoy nature by going hiking, backpacking, rock climbing or camping with my wife and friends. Living a healthy, active lifestyle is very important to me.

My Bachelor’s degree is from Salisbury University on Maryland’s eastern shore. Following the completion of my undergraduate degree in physical education in 2009, I enrolled in a one of a kind Master’s degree program at the University of Northern Iowa, focusing on teaching with technology specific to the physical education setting. This Master’s program coupled pedagogical and technology classes at the university with a teaching immersion experience within Grundy Center Community School District. I taught at Grundy Center Elementary School during the day where I put the theory and content I was learning from my Master’s classes into practice on a daily basis. While teaching in Grundy Center, I had the chance to implement heart rate monitors, activity monitors, fitness assessment software and computer projection systems to enhance instruction and help his students make the “brain-body” connection. It was here that I learned not only how to effectively incorporate this type technology to supplement instruction, but also how to effectively manage it. I have written and won multiple local and national grants in order to acquire funding to use my knowledge and experience to effectively implement a heart rate monitoring program and an activity monitoring programs at Waverly over the past several years.

Brian Hull - Phys Ed Ambassador

Hello everybody! First and foremost, I am extremely excited to be a part of the Heart Tech Plus Ambassador team! Currently, I am a Physical Education teacher in Denver, Colorado at Bruce Randolph School (Denver Public Schools). I was one of the first Physical Education teachers that partnered with Heart Tech Plus and have been using their products, web portal, and app for the last two years.

I am completely “all in” as a Physical Education teacher. I personally believe that Physical Education is the most important subject in today’s schools, due to the fact that more and more studies keep coming out proving the correlation between students’ academic success and behavior to physical activity. Furthermore, I get so excited when implementing technology into my classes, such as my Heart Tech Plus heart rate monitors. I immediately become passionate of my students’ success when I witness them taking ownership of their own learning and evaluating their heart rate monitor data and goals!

On another note, for my undergraduate studies, I attended two colleges: Metro State University in Denver, Colorado and Sterling College in Sterling, Kansas. At these schools, I had the privilege of playing collegiate baseball and earning my degree in Human Performance and Sport with a teaching licensure in K-12 Physical Education. I have been using my P.E. degree for 6 years now; I’ve been teaching in public schools in Denver for 5 years and in 2011, I was the Recreation Coordinator at an adult Detention Center!

Last but not least, when I am not at work, I live for the time that I can spend with my wife, Danielle, my 1 month old son Aiden (who was born on Thanksgiving 2016) and my yellow Labrador Retriever Jake! I also try to find time to spend with my identical twin brother, Brad, who is also a Physical Education teacher in Wheat Ridge, Colorado!
