Dr. Maurice Cephus | Aloha

Undergraduate work at Patton College...right down the street from Oracle area where Steph Curry handles his business (for the time being).
Graduate work at Palmer West Chiropractic in my hometown of San Jose, CA

I'm passionate about seeing my patients improve their health and quality of living through chiropractic care. I can't put into words how gratifying it is to be apart of their recovery to health and wellness!

Becoming a partner with Centro has given me the freedom to focus all my energy towards my strength... patient care.

I enjoy eating good food...I know, I know everyone likes to eat, but I'm talking about the kind of eating where you grab a pillow and blanket afterwards. Food and spines communicate with me, we have conversations together you understand; a bond! lol


Dr. Richard Hill | McMinnville

Undergraduate degree: BS in Military History with a minor in Systems Engineering from the US Military Academy. DC from Western States Chiropractic College (now University of Western States). Graduate of the Whiplash Biomechanics and Traumatology course from Spine Research Institute of San Diego (2013, 2018).

I'm passionate about understanding individual injury cases to make sure that patients not only get the best care and rehabilitation right now, but also make sure they have all the tools they need to ensure the fullest recovery possible for the future.

Working with Centro allows me to meet so many people who would otherwise live and work in pain and help them recover from their injuries and equip them to remain pain-free. When your not helping people get better, what do you enjoy doing? Riding my motorcycle and target shooting.


Dr. Adam Isfeld DC, MS | Gresham

 I am a graduate of UWS Chiropractic School. I was born and raised in Gladstone until 11 years old when my family moved to Happy Valley. I attended Clackamas High School, where I was an 8-time letter earner and OSAA All-State in 3 sports (football, wrestling, track & field). I was offered to continue my football career at the University of Oregon in the early 2000’s. I participated in 5 bowl games and 2 Pac-10 Championships. I graduated with a BS in Exercise Science and a minor in Strength & Conditioning.

 I started my work career in construction as a carpenter in commercial dwellings. I then accepted a job as a Safety Director for a mining and metal fabrication shop. I worked mostly with training employees, ergonomics, occupational safety and worker’s compensation. I owned a construction company that did mostly remodels and general contractor work. I finished my past career as a safety manager on the Intel campus working closely with OSHA, BOLI and the Worker’s Compensation Division. 

 I left my job at Intel to pursue a career with Portland Fire & Rescue, who put me through EMT training, but I ultimately decided to attend UWS to pursue my Doctorate in Chiropractic Medicine and a Master’s Degree in Sports Medicine. My hope is to be part of the healing solutions that so many people are in need of today. My biggest goal is to raise awareness of pain remediation and help everyone that I can in a more natural manner.


Dr. Jason Kennedy | Woodburn

Dr. Kennedy was born and raised in Southern California. His first experience with chiropractic was as a senior in high school when he took a field trip to the Los Angeles College of Chiropractic (LACC) in Whittier, CA. He was so impressed with the facilities and all of the things a Chiropractor could do, that he signed up for their weekend course to become Certified Chiropractic Assistant. It was during this course that he fell in love with the profession and decided to devote his life to it. Many years later, while in his first years of practice, he felt a call to service and enlisted in the United States Army. After 4 years in the service he decided to further his education and enrolled in the Acupuncture program at his alma mater, now called Southern California University of Health Sciences (LACC). After he graduated with his Masters degree he moved to Oregon to experience all that life in the pacific northwest had to offer. (This was an easy decision as he had been visiting Keizer for about 5 years and just fell in love with the kindness of the people and the natural beauty of the area.)

Dr. Kennedy learned about Centro Chiropractic from his colleague, Alex Alcaraz. He and Alex both attended the same Acupuncture school and after Alex moved to Keizer and started working for Centro as a massage therapist he recommended that Dr. Kennedy meet with the owner. Centro Chiropractic allows Dr. Kennedy to care for his patients with compassion and to provide the kind of high quality health care that people deserve. He is able to give them his full attention and the best experience every single visit. Every day is a reminder that chiropractic care is a wonderful and powerful way of restoring function to peoples bodies and lives. At home Dr. Kennedy has a very neurotic Australian Shepherd named Snickers that loves to go on walks and get a little too excited about other dogs. Dr. Kennedy also loves to hike and just be in nature. He enjoys table top and card games and loves to spend time with friends.
