Mike lives a healthy and active lifestyle with many hobbies including snowboarding, mountain biking, basketball and golf. Upon turning 40, Mike, noticing changes in his body, began to explore longevity medicine. What started as a personal interest, gradually developed into a lifestyle, which attracted the interests of friends and family. This momentum eventually grew into Mike starting BodyTimeMD in the fall of 2022 to provide an Executive Longevity Medicine service to those with shared values in health.
Crizen Hasegawa
Crizen graduated from Purdue University in 2001 and worked in aerospace industry as a project manager for 4 years.

Shortly after getting married in 2005, Crizen left the aerospace industry and went on to Cosmetology school. She was quick to build a loyal clientele and she opened a salon in downtown Chicago just as Mike decided to go to medical school. Crizen and Mike had 3 children while Mike was in medical school and ER training. Crizen supported her family for almost 10 years before the family decided to move to Austin for a better lifestyle.
Crizen was not always into health and fitness but after having her children, she saw the importance of living a healthy and active life. She has since become a fitness fanatic and works out at 5am every day. She also became passionate about nutrition through her health journey.

In 2012 Jenny traded in the briefcase for the diaper bag to stay home and raise their boy and girl twins. Raising twins has sharpened skills such as patience, planning and logistics. As Operations Manager, logistics and planning will be key to success in her role working closely with clients.

Originally from New York City, Ruby grew up in the fashion industry, modeling herself, but was always drawn to helping people. After graduating from Vassar college and working as an EMT and research technician, she went on to earn her medical degree from Tufts University in Boston and completed her Emergency Medicine residency at the University of Massachusetts in 2006. After moving to Austin, TX in 2012 and working for one of the large hospital systems while raising 3 kids and supporting her husband’s new business, Ruby realized the impact her work lifestyle was having on her health and felt compelled to practice medicine the way she originally envisioned: focused compassionate care. She went on to pursue her interest in complimentary medicine and completed a fellowship at the Andrew Weil Center for Integrative Medicine at the University of Arizona in 2019.
As a lifelong student of medicine struggling with her own journey through perimenopause, Ruby took on more training and recently became a certified functional medicine practitioner through the Institute for Functional Medicine this past spring. Through science-based integrative and functional methods that combine nutrition, mind-body awareness, movement and hands-on healing, Ruby found her passion for preventative care, focusing on optimizing metabolic, gut and hormone function. Outside of medicine, Ruby delights in equestrian sports with her two daughters, exploring all forms of music with her son, and cherishes quality time centered around healthy cooking and laughter with her husband.

Kathy Redden
Kathy’s journey as a leader in health and fitness began over 30 years ago while attending the University of Texas at Austin where she led group exercise classes at UT as well as over 20 local gyms and fitness studios while acquiring her Bachelor of Business degree in Accounting. Her speciality and intense passion has always been influencing and changing lifestyles. After many years of working in auditing, consulting and financial roles for her “day job”, while also coaching and training fitness clients on the side, she realized a career in Health and Fitness was a more well-suited match for her future.
Kathy eventually opened Tetra Fitness in 2012, an elite training facility in Austin. During her tenure, she created over 20 new class formats while also "Training Trainers" which developed many new Personal Trainers and Instructors in Austin. One of Kathy's favorite programs was the "T.O.O.S. groups”. This group of "Totally Out Of Shape" participants was led through a 3-month class to get them from a sedentary lifestyle to a routine of regular exercise and healthy eating habits.
Kathy has twice participated in CRUCE DE LOS ANDES (100K trail run) and the BC BIKE RACE (7-day Mountain Bike Stage Race) as well as dozens of Adventure Trail Races all over the United States. She has also led, organized and managed 12 Vacation Transformation BootCamps all over the world where groups of clients are "in her healthy care" for 5-7 days of adventure and fitness. When not training clients, you can find Kathy on her bike, surfing on Lake Austin, playing volleyball in the sand, or climbing a mountain.
