        Dr. Joe O'Tool

        Doctor of Chiropractic, S.F.M.A., A.R.T.

        Dr. Joe grew up on an acreage in western Iowa. As a child, Dr. Joe was fascinated with the human body and the wonderful healing potential it held, but it wasn’t until late in high school that he connected his interest with becoming a chiropractor. Through playing and coaching both football and basketball, he saw the impact that proper movement – or lack thereof – could have on the body. Prior to becoming a chiropractor, Dr. Joe accumulated a vast array of life experiences, including soil and agricultural testing, working in manual labor jobs, serving as a medication manager at a mental care facility, competing in triathlons, Crossfitting, and living abroad in China.

        Through it all, his passion for helping others and supporting true health rose to the top. Dr. Joe has had the opportunity to work with many healthcare professionals, from medical doctors and radiologists to Traditional Chinese Medicine doctors and physical therapists. Dr. Joe graduated from Palmer College of Chiropractic and often returns to speak at his Alma Mater. He currently serves as the official chiropractor for Relay Iowa (the longest relay race in the world), teaches anatomy & kinesiology at Body Wisdom Massage Therapy School and coaches high school football in his community. He and his wife, Angie, often travel throughout the US and internationally to speak on various health topics. In his spare time, Dr. Joe remains active through triathlons, Crossfit, and basketball. He enjoys being involved in his local church and loves spending time with his wife and three children. Dr. Joe sees patients out of our Grimes/Johnston location and often speaks on behalf of Lifestream at health workshops throughout the Des Moines Metro area.

          Dr. Sam O'Tool

          Doctor of Chiropractic

          Dr. Sam grew up in a large family on the outskirts of a small town in western Iowa. A natural competitor, Dr. Sam was active in any type of sport he could find, including basketball, football, and weight lifting. During his basketball career he sustained two major knee injuries that required complete reconstructive surgery. While Dr. Sam has always had an interest in the human body and how it functions, these injuries sparked a desire to help others function properly so they can prevent their own injuries and improve their performance. While getting his doctorate at Palmer College of Chiropractic, Dr. Sam had the opportunity to work under the guidance of an Olympic and professional sports chiropractor.

          Today, Dr. Sam continues to pursue his passion for proper function with his post-doctorate neurology program through Carrick Institute of Clinical Neurology. When not serving patients at our Ankeny & Ames locations, Dr. Sam loves spending time with his wife and daughters. He loves staying active and is driven to compete at whatever he does. He is a regular instructor at Body Wisdom Massage Therapy School and lectures often in various locations at the Iowa State Research Park.

              Rachel Swanson

              Healing Food Specialist and Massage Therapist

              Rachel grew up with the phrase, ‘be a jack-of-all-trades and a master-of-one.’ Since she simply enjoys the beauty of life, it took some exploration to uncover her passion in life: wholeness. She says, “Wholeness is complete well being in one’s body, soul, and spirit.” She truly receives satisfaction when seeing an individual’s life transformed from chronic fatigue to maximum energy; shooting pain in the feet to long walks in the park, etc. When working with patients, her goal is to maximize their fullest potential outside of a clinic.

              She became a Certified Healing Food Specialist in 2009 and an NTP in 2010 while studying in Oregon. In the world today, society is detached from real food; what it is and what it does for you. Her love for food transfers over into educating people on making wise food choices for optimal living. Beyond giving advice for proper eating, Rachel performs a functional nutrition exam to determine your deficiencies and determine any specific supplements your body might need.

              She also became a Licensed Massage Therapist in 2012 and specializes in clinical sports, and barefoot deep tissue. Along with fueling the inside, she finds an equal value in the health of movement. Because many occupations require a long stint of sitting, a lot of injuries happen that could be prevented if proper care is given. Her blend of understanding the importance of movement, and proper nutrition to fuel movement, gives Rachel a unique approach to care for your health.
