Dr. Jeff Hartwell - D.C.

As a child, my mother was helped immensely with migraine headaches, neck and back pain by her chiropractor.  I was so impressed with this that I decided to pursue a chiropractic career as a 9th grader.  I am a 1988 graduate of Western States Chiropractic College.  I obtained a Licensed Massage Therapist status while attending Chiropractic College, and was able to supplement my hands on experience by working with athletes and other patients for years prior to graduating as a chiropractor. 

From 1988 through 1992, I worked as an associate doctor at Robinson Chiropractic Clinic in Molalla, OR, where in addition to standard treatment, I was able to run a rehab center for injury recovery.

I enjoy treating all kinds of conditions involving the muscles, bones, joints, and nerves.  Patients often comment on the thoroughness of my care.  A careful look at the musculoskeletal system from the feet to the head is a must when treating many cases.  I give credit to the Lord Jesus Christ for the gifts He has given me in being compassionate and skilled in using my hands to assist in patient's recovery.

Dr. Dain Cason - D.C.

Dr. Cason grew up with chiropractic care as his grandfather practiced in the Portland area for over 60 years. So he saw from a young age how influential “whole body” care can be. 

Dr. Cason joined the Marine Corp right out of High school and served in Iraq during the 2003 invasion. This taught him coping and communication skills. He served a mission for 2 years in San Antonio TX where he learned to speak Spanish and to serve wholeheartedly. He then attended OSU where he participated on the triathlon and cheerleading teams. Here he earned a Bachelor of Science in Pre- Physical Therapy. With that foundation he completed not only the standard Doctorate in Chiropractic, but also earned a Master’s degree in Exercise and Sports Science. He is a Certified Chiropractic Sports Physician as well as a Certified Strength and Conditioning Specialist. He has been through additional training in diagnosing and treating whiplash injury, and utilizing Active Release Technique. Because of his training, Dr. Cason offers a very cutting edge approach to treating injuries to joints, and muscles, with his passion being in rehabbing sports injuries.

Dr. Cason enjoys competitive running, cycling, and swimming. He competes regularly in Sprint, Olympic, half iron and Ironman triathlon distances. He is married with two young children. As a family, they plan to re-locate their home from Portland to the Canby area.

Dr. Andrew Patterson - D.C.

I was born and raised in West Linn and am the 3rd generation in my family to graduate from West Linn High School. 

I've been a chiropractic patient myself since a serious snowboard accident in 2000 left me with agonizing back pain. Immediate chiropractic care following the accident and regular adjustments since have been integral to my recovery. This regular care has also given me unique insight into the patient perspective, allowing me to personally relate to and understand my patients. Additionally, mentorship by my friend Dr. Jeff McNown helped my discover my calling to be a chiropractor. 

With a deep desire to help people and a fascination of how the body works, I attended both Cleveland Chiropractic College and the University of Southern California Health Sciences in Los Angeles where I graduated magna cum laude with a B.S. in Human Biology and Doctor of Chiropractic degrees. 

During my schooling and in the 2 years of private-practice that followed in L.A., I developed a sports medicine focus with an additional certification as a Certified Strength and Conditioning Specialist as well as work with collegiate and CrossFit athletes in the clinical and competition arenas. I always try to "see in my mind" what happened with any given patient's injury, be-it sports injury, car accident, slip-and-fall, etc., so I can better understand the injury, how I can help that person recover, and what we can do to prevent re-injury. 

Feeling the call to return home, I moved back to the great Pacific Northwest in August 2015 and joined the Hartwell Chiropractic team where I feel I belong. 

I now call Canby my home and will take any chance I get to be outside doing CrossFit, Spartan races, mountain biking, snowboarding, waterskiing, and backpacking.

Dr. Greiner attended Pacific University in Forest Grove, OR and received a Bachelor’s in Science in Exercise Science with a minor in Spanish. After graduating, she volunteered in Africa for 5 months working and teaching in rural communities and aiding women’s groups in health and financing for villages. It was during this time that she found her desire to work with and help others, as well as, began to discover the healing power of nature.

She also trained as a doula and studied with naturopathic homebirth midwives while in her naturopathic education.  She is also passionate about women’s health and pediatric care. She is trained in holistic pelvic floor therapy, a therapy involving trigger points in the pelvic floor combined with restorative breath-work tools improving connectivity to the body. This process is for women in all stages in life and enhances the circulation and flow of energy in the pelvic floor and can improve symptoms of incontinence, pain, urinary complaints and chronic pain that can develop in that area if left untreated.
 
Dr. Greiner completed a 1-year residency focusing on holistic primary care, drainage therapy, nutrition counseling, weight loss, women’s health and pediatrics. She is also very well trained in neural therapy, a form of mesotherapy that is used to treat chronic pain, chronic illness and athletic injuries.
