The experience was very professional and educational and thorough. The experience shown in my condition was easily recognizable. Always a joy to feel better when I walk out the door.
August 14, 2024Bill P.Verified patient
Im a 74 year old woman who has suffered with back issues since I was 15 years old. I've had 2 long term Chiropractors during those years. Dr Fennama is the first to incorporate exercises during my appointment time in conjunction with an adjustment. I've only had 2 appointments but I'm already feeling a marked improvement. I'm looking forward to continuing my treatment program and am expecting continued improvement
July 15, 2024Kathryn D.Verified patient
Friendly and comfortable environment. Everyone listened and was willing to work with whatever I needed to make sure the problem was fixed. It did not feel rushed like most offices can make you feel sometimes.
December 5, 2023Susan T.Verified patient
I have every confidence that my issue will be taken care of. I was very pleased with how Dr. Fennema took the time to evaluate me and listen to my concerns. I look forward to my next visit.
August 31, 2023Linda J.Verified patient
It was a great first experience. I knew from previous experience that I wouldn't be adjusted until x-rays came back but I got a very good feel for the office, his touch, and how smoothly everything runs there.

I have been afraid of chiropractors for a very long time due to a bad experience. Dr. Jason is remarkable. Very kind, patient and conscientious. I will be going back for at least 6 weeks, and I plan to go after that periodically for maintenance. If he could make me comfortable, he’s very good. I’m sorry I waited in pain for months before seeing him.
October 5, 2021Lisa J.Verified patient
Dr. Fennema listened carefully, explained clearly, and began a program to help me. he was friendly and took time with me. I am very impressed.

I have been treated by Dr. J and his staff for many years with back physical therapy and (2) total knee replacements. Due to the experienced staff and their deep understanding of therapy, I have been able to achieve full recovery and have maximized the outcomes with their treatments and care.
May 3, 2021Gary M.Verified patient
Currently go to seem Dr Jason 3 times a week. I suffered from headaches for a long time and thought they were just a normal thing. I started feeling better within the first week with Dr Jason. Now I rarely have headaches and if I do it’s probably from another reason, not my posture.
September 25, 2020Matt M.Verified patient
Jason was very knowledgeable, friendlyand to the point. I’ve been to quite a few chiropractors and have been in the gym industry for 6 years and this was my best encounter yet.

I visited Dr. Fennema's office after I had hurt my lower back whilst working out. To make a long story short, I was seeking some relief for my back pain, which I did not receive after 2 visits.
What I did receive, was a "consultation" that ultimate led to a heavily suggested 24 chiropractor visits, where they conveniently lower the price if you pay upfront. I was weary of the amount of visits suggested and cost, so I visited a different chiropractor the same day (who helped to alleviate my pain that visit, by the way).
I was also called repeatedly late at night by the doctor on his personal cell phone urgently seeking to start me on this 24 visit program.
Outside of the staff being very friendly, my experience with this office was altogether poor.

Dr. Jason was very helpful when explaining my X-rays and spinal conditions. I found the program he put me on releived my discomfort quickly. He was very thourough when explaining how the program was improving my spine. The staff is very friendly and helpful as well.

I had an excellent visit. The practice is busy but each patient receives personal care and attention from several members of the staff throughout the visit. My care is continuously high-caliber, quick and thorough. I reap the benefits of each visit for several days after, as well as long term improvements to my chiropractic and overall health.

All of the staff at RHW are professional, friendly and attentive. I came in with terrible back and leg pain and with regular treatment, I am feeling much better. I would highly recommend RHW. In fact, I have.
