I am a devoted chiropractor committed to enriching lives through optimal health. In 2012, I became a personal trainer while in service in the U.S. Marines. Since then, I have guided individuals of all ages to achieve their health and wellness goals. With a degree in kinesiology and rehabilitation science from the University of Hawaii, I developed a passion for complementary and alternative medicine, emphasizing the body's innate healing abilities. After graduating with a doctorate in chiropractics from Southern California University of Health Sciences, I have utilized my expertise in chiropractic, rehabilitation, and nutrition to empower patients towards optimal well-being.

 I am a  compassionate healthcare professional, dedicated to helping patients, whether recovering athletes or those facing chronic pain, to achieve their health and wellness goals.
