The Peninsula Y is a valuable resource to our community providing an array of programs and opportunities for every age level. It is a privilege to serve as a instructor and personal trainer and assist members in attaining their goals, to reach their full potential of fitness and vitality. My educational background is in Fine Arts, I also have degrees in childhood education. I have a masters degree and PHD in human resources which includes resolutions of strife between individuals and the administration. I teach classes at the Y in Pilates, 50/50 a combo yoga/pilates class and body balance which combines pilates and strength exercises. In all of my classes there is an emphasis on core strength, stability and body alignment. I have certification from the Y organization as well as national certification in advanced personal training through NCSF (National Council of Strength and Fitness). My intention is to develop a personal training program to suit each individual's unique needs and goals. I wish to achieve the highest level of fitness, self esteem and confidence for every client. I want you to look forward to your workout! Physical activity not only improves strength and stamina of the physical body it also improves your emotional outlook and gives you a more positive and upbeat perception of life. I will help you to attain the results you have been looking for and a body that you will be proud of. I look forward to working with you.

He has been working in the fitness industry for two years, but has been involved in fitness, working out, and sports for many. His goal in training is to provide a fun and effective way to improve the overall quality of life for all of my clients, helping them realize their full potential while reaching their goals and making their activities of daily living easier.

John Squire

John grew up in England and from an early age loved playing sports. He began playing soccer at a young age and was training to play professionally. He still enjoys playing indoor soccer today. John has always enjoyed the fitness training aspect of playing sports and continued over the years to be fitness oriented. Four years ago he had the opportunity to move to the USA and pursue a career in the fitness field. Shortly after arriving he attained his ACE Certification in Personal Training and looked to gain employment at a gym. He was fortunate enough to work for a charity organization, where he worked closely with Physiotherapists providing fitness training for elderly clients, people of all ages recovering from severe injuries and clients with long term medical conditions. This involved improvisation and finding alternative techniques to achieve fitness goals to accommodate for the limitations of his clients. John loves meeting new people and helping them achieve their fitness goals, whether the goal is to strengthen muscle, burn fat, gain more flexibility or just a desire to lead a healthier lifestyle. He has a great sense of humor and brings to this his clients so they can see that exercise and being healthy is not a chore, but can be a positive part of life.
