Teachings we offer include the following:
Yang Style Tai Chi Chuan- This style of Tai Chi Chuan (Taijiquan) is a martial art created by Yang Lu Chan from the Chen family style he learned and passed down through his family until his grandson Yang Cheng Fu began teaching it all around China popularizing the art where it became renowned for not only it's martial art skills but for its amazing health benefits. at Tide Change Tai Chi we teach two main Tai Chi Chuan forms. We teach the 24 Beijing form based on Yang Style that was popularized in China as a system of health care for the people and is the most popular Tai Chi form in the world. The form is perfect for this goal as it is long enough to attain great benefits but not too long that it is inconvenient to do for a daily health improvement and maintenance routine. Additionally we teach a longer 60 movement Yang Style form that lends itself greatly to feeling the flow of chi (Qi) energy in the body and has a more complete version of the Yang Style of Tai Chi with its additional movements. This form is based more in Grandmaster Cheng Man Ching's Yang style Interpretation. The Yang style of Tai Chi Chuan is a gentle, smooth and flowing art many describe as a moving meditation that combines breathing techniques with soft movements and is the most sought after and popular style of Tai Chi for health and wellness.
Qigong- An ancient Chinese art that translates as "energy work or energy skill'. The qigong we teach has several varieties from slow, flowing movements that greatly improve strength, balance, coordination and energy flow to standing qigong static postures known as Zhan Zhuang which translates as "Standing Stake" Qigong that teaches structure and improves the connection of the body, mind, breath and energy. We also teach a nearly 1000 year old Qigong routine called Baduanjin or "Eight Pieces of Brocade". Brocade is a fine patterned cloth material considered a treasure in ancient times and this form was named as such because it has eight moving exercise patterns and is a treasure for your health when used as a regular health maintenance routine. Baduanjin is known for greatly improving flexibility, strength, balance, coordination and more. The art of qigong is truly amazing for the body and mind.
Meditation- The meditation we teach ranges from Mindfulness meditation, Concentration meditation, Positive affirmation meditation, Walking meditation, Zen meditation (Chan is the word for Zen in Chinese) where clearing the mind and focusing on living in the present moment is the key and then into Taoist (Daoist) methods of meditation such as Wuji meditation (similar to zen meditation with a clear mind approach but with the optimism that with a clear mind there are then infinite possibilities), Zhang Zhuang meditation (Standing Stake Qigong) to energy movement meditation which is more active in its approach. One method of cultivating, building and storing Chi energy in the body is an ancient method known as Embryonic Breathing Meditation which combines focused breathing patterns with the mindful leading of energy in the body to accomplish the desired goals. Another active method of meditation we teach is known as Microcosmic Orbit Meditation where you learn to circulate the energy of the body through the two main energy meridians coordinating breath with the mind's intent (known as the Yi in Chinese). These Taoist (Daoist) methods of meditation are thousands of years old and are very deep in their scope. They enhance health, feel amazing and are excellent for the body and mind when the correct desired results are achieved.
Tai Chi Chuan as a martial art-Tai Chi Chuan has flourished for its incredible health benefits but is actually a Kung Fu (Gung Fu) style based on Daoist philosophy. Shifu Justin Guerin is a highly experienced practitioner of Tai Chi Chuan as a martial art and teaches both the health aspects and the martial art side for anyone seeking those methods.
Self Defense-Shifu Justin Guerin has developed a self defense course for people with no training to learn combining awareness with simple yet highly effective methods to keep oneself safe in the dangers of our modern world.
Jiu Jitsu/MMA-Sensei Justin Guerin teaches a full Jiu Jitsu program. This program is taught as a traditional Japanese Budo or "Martial Way" and can be used as a self defense modern martial art or for sport fighting. This Is the martial art of the Samurai warriors of Japan's past. In this program you will receive training in all the Japanese Jiu Jitsu techniques including striking, kicking, defense, joint locks, chokes, vital point striking and manipulation, submissions, grappling both standing and groundfighting, throws, takedowns, weapons defense, dealing with multiple attackers, general self defense, situational awareness, zen training, studying classical texts pertinent to Samurai Jiu Jitsu and more. Some schools teach only the ground aspects or the throwing aspects of Jiu Jitsu and some focus only on sport competition and not the real Jiu Jitsu. With Tide Change's Jiu Jitsu program you will receive the whole art of Jiu Jitsu leaving no stone unturned. Training is also done in the traditional Gi and without the Gi.
Tide Change also has a full Mixed Martial Arts program included and interwoven with our Jiu Jitsu program combing Jiu Jitsu with the skills of boxing, kickboxing, clinch fighting, wrestling, grappling, grappling with striking combined, throws, takedowns and developing a winning mindset as well as the body's physical attributes to perform at your best.

Water can be powerful and raging or tranquil and calm, a perfect symbol of Tai Chi's hard and soft. Tai Chi Chuan was created with Qigong and Daoist philosophy built into its foundation. Tai Chi goes with the flow of the current. The art is as deep as the depths of the ocean and it's your choice to explore what you want from it. You can wade in the shallow waters of Tai Chi or dive down into its depths. We are here to guide you in that experience. Tai Chi will teach you how to be in the moment.
