John W. Doolittle, CAPT, USN (Ret)

Chief Business Development Officer, KAATSU Global, Inc.

John is from Walnut Creek, California.  He earned a Bachelor of Science degree from the United States Air Force Academy in 1992, and a Master’s Degree in Defense Analysis, Special Operations Low Intensity Conflict from the Naval Postgraduate School in 2005.  After 25 years in Naval Special Warfare (SEAL Teams), he recently retired and accepted a position at KAATSU Global, an organization focused on improving injury rehabilitation, sports recovery, and human performance across the globe.

After an inter-service transfer and “cross-commissioning” from the Air Force to the Navy in 1992, John transferred to the Navy and completed Basic Underwater Demolition/SEAL (BUD/S) training as the Class Leader of BUD/S Class 213.  From 1996 to 2017, John was assigned to various SEAL Teams and conducted multiple deployments throughout the European, African, Pacific, and Middle East theaters of operations.  While getting his Master’s degree, he did a solo swim across the English Channel in memory of a fallen teammate & friend, to raise money for the UDT/ SEAL Association and the Navy SEAL Foundation.  Most of his Navy career was focused on our military’s reaction to 9/11; a busy time for John and his family.  John’s last duty station in the Navy was at U.S. Special Operations Command (USSOCOM), where he led the USSOCOM Human Performance Program (HPP), which employs a small army of physical therapists, strength coaches, trainers, nutritionists, psychologists, and counselors.  These resources are now embedded in all of our nation’s special operations command elements around the globe, and are focused on repairing and sustaining our nation’s most important weapon system; the Soldier, Sailor, Airman or Marine.  It was during this time that John was introduced to the impressive rapid rehabilitation and human performance capabilities associated with KAATSU.

John and his wife, Katie, are raising three children: Sean (16), Ryan (14), and Meg (12).  The Navy has taken the Doolittles around the world; now John brings his proven leadership experience to the KAATSU Global Team.

Leidy Weinstein

President of LifeForce IQ

Leidy Weinstein grew up in the slums outside of Cali, Colombia. Leidy was raised by her grandmother and did graduate from the local school at 16 but became pregnant that year. At 17 years old she found herself sharing a room with a relative in Cali and raising a newborn. Then, just two years later, she was shot by robbers; her right arm was shattered and had to be reconstructed with metal plates. In 2014 Leidy met her soul mate and husband David Weinstein and got pregnant. She gained over 100 pounds! When their baby was born Leidy tipped the scales at 250 pounds. To make matters even worse the plates in her arm broke during the pregnancy and she could not use her left arm. After a seven-hour surgery, they were able to reconstruct her nerves and put in new plates. One day in the summer of 2016, while she was recovering Leidy, proclaimed that she wanted to help women lose weight and take control of their health starting with herself. She lost 100 pounds, sculpted her body, and won a bikini championship. She started the company LifeForce IQ with her husband David. LifeForce IQ takes a radically different approach to optimize health and vitality. It approaches each person by transforming their health biologically, one cell at a time. The equipment and training protocol combines t “Kaatsu”, a Japanese compression training system, with traditional exercise. Today Leidy is the president of Lifeforce IQ and a professional Kaatsu personal trainer.
