“DR.J was great straight forward and to the point like I want from my doctors. Very thorough !! Office was clean and with multiple tools to help with my needs I feel confident I will be feeling better in just a few short visits. Don’t hesitate to visit for all your chiropractic needs. Thanks again Doc”

“Very informative and communicative. Waiting area very presentable, clean and nice. Examination room very cold because it's the back near the door, it was extremely cold out so I'd say it was my only discomfort although a small heater was provided. This didn't deter me from definitely going back. I learned a whole lot about my self and my concerns were addressed and doc made sure to ensure I was comfortable and understood exactly what was going on and what to expect moving forward if I continued with his services. He broke it down from the finances and and the physical changes that will occur. It was an amazing experience ”

Dr John was amazing! Great bed side manner explained everything and very pleasant. He hears you out on everything you have to say. I can’t wait to continue care with him while he helps me on this journey to fixing my back problems.

Although the wait time was long, I am satisfied with Dr. John’s service. He is pleasant …which made up for wait. He conducts thorough assessments right in the comfort of his office…X-rays as well. Overall, my experience was good. My back pain subsided after just one treatment. Will follow up.

This is one of the best chiropractor visits I have ever been to. The Dr. Was very polite and patient. Made you feel as if this was a home visit. Definitely knows what he is speaking about. Currently pregnant and my alignment was so comfortable and relaxing. I have already booked my next appointment and would advise you to try him also.

I was blown away by the experience with Dr. John from start to finish. He is extremely compassionate and makes the plunge into chiropractic an easy one for ‘non-believers’ through his charisma and clear knowledge. His technology is like none I have seen in a chiropractic office. He is humble, kind and makes you leave knowing there is a clear plan in place to address your issue. Have already recommended him to multiple people and I left the office about an hour ago.
December 19, 2019Katie S.Verified patient
He was patient and understanding and up front with expectations. I was given time to ask questions and to further understand my treatment plan. Hopeful that the plan helps with problems.
November 7, 2019Adero F.Verified patient
Nice office. Young lady at front desk was very pleasant. Muni-Metered parking on the block $1.50 for two hrs. Free municipal parking around the corner. Come at least half hr before appointment to fill out forms-lots of questions. I was taken in within 10 minutes after completing forms. His consultation included standing on two scales to determine weight distribution, assessing posture distribution, infrared device to locate hot spots in the spine, a manual assessment to pinpoint misaligned vertebra, and xrays of neck and back taken in the office. Cold laser therapy followed by warm hydrotherapy was my first session. No adjustments untill after xrays are processed and reviewed which will be my next appointment.
October 7, 2019Carolyn C.Verified patient

I am looking forward to receiving treat from Dr. Gehnrich.
April 24, 2019Jaclyn V.Verified patient
This was not your typical chiropractor visit. The office is absolutely immaculate and the staff was extremely warm and welcoming. Dr Gehrich has an unbelievable bedside manner and you can really see that he has an intense desire to help. He carefully listens to your concerns, conducts a myriad of tests and carefully constructs a treatment plan based on his detailed analysis. The technology in the office is second to none.
I felt like I was very well taken care of, all my questions were answered and I’m extremely happy with my visit. I’d highly recommend.
November 7, 2018Daniel D.Verified patient

May 4, 2018Sean R.Verified patient
I was very pleased with my visit. Dr. John listened carefully to my complaints of chronic back pain and he came up with a treatment plan that works. I appreciate his holistic approach to chiropractic care. His appointment times are very flexible and this allows me to keep my visits despite my crazy work schedule. Dr. Johns up beat bedside manner is wonderful and I can tell that he enjoys what he does.
February 12, 2018Maloree B.Verified patient
Speaks really fast, i felt like i was being sold something, rather than carefully explaining what's happening and how to fix it. He explained, but slow it down please.
More than 1 year agoInitials hidden
After going through countless doctors and therapists for chronic back pain I thought that my problems would never be solved. No one was able to simply look at me and give me a diagnosis of my problems until I went to John. He is very knowledgeable about the human body as a whole and makes you feel like you will be able to overcome the situation eventually. I would highly recommend to anyone and I do look forward to working with this talented man.
January 23, 2018Isaac D.Verified patient
He is so wonderful and explains everything that your body is going through in your time spend wit him. The office is so relaxing and i always leave with a smile on my face. My back pain and even little aches and pains have gone away since I began seeing him. I can not say enough praises for everything he has done for me.

He was very knowledgeable and informative??
November 9, 2016Bernadette I.Verified patient
I could not be happier with the results I've had under Dr. John's care. I do not have back pain but Dr. John has been able to help me with some issues I've been having with my shoulder and leg. I had been in physical therapy for months and saw some improvement with my leg but almost no change in my shoulder. After one visit (not exaggerating) with Dr. John there was a marked improvement in both. He even helped relieve pain in my knee that has been there so long, I had gotten used to it. Dr. John practices a holistic approach that leads toward healing rather than masking pain.
August 31, 2016Deborah U.Verified patient
I would recommend anyone to Dr. Gehnrich. That's hard for me to say because I am VERY PICKY. When I walked into the office I felt like j was walking into a spa. The ambiance was very relaxing. The office is very clean. Dr. Gehnrich greeted me as he walked up to the front desk. He was very friendly and warm. He made me feel very comfortable. He took his time and explained everything. He listened to my concerns. Very caring. I LOVE the fact that his practice focuses on wholistic care. If you're looking for a great chiropractor contact Dr. Gehnrich you won't regret it.
August 9, 2016Chiniqua D.Verified patient
Rhino Chiropractic has had a tremendous positive impact on my quality of life. Spending most of my day sitting at a desk typing away, I have developed discomfort on my neck and back. This discomfort built up over the years and eventually became too much to bear. When I first came to Rhino Chiropractic to see Dr. John Gehnrich, I was in such pain that sleeping had become a luxury. After a few sessions, my life started to get back to normal. While I was in regular treatment, my tendinitis on my right wrist flared up. My wife happens to mention it to Dr. Gehnrich who with an adjustment during one of my sessions corrected my wrist and the pain went away. The attention given to my care and wellbeing is unmatched by other places I have been to. I want to thank Dr. Gehnrich for helping me get back on track with my health.

I love Dr. John, he knows just how to meet each specific patients needs and goals and he does it with a cheery disposition. Every adjustment is a pleasure and my progress & immune system stamina is remarkable.

Dr. John was able to treat my injury and showed a caring disposition. His positive energy made me confident. I would get better in the quickest my body would allow.

I've been treated by Dr. John for 2 months now. I came because of pain in my right hip & groin, and I had a terrible limp. He used the cold laser on my hip & groin and I've seen a remarkable improvement in the pain & also the way I walk. In addition, I had trouble swallowing & had a CT scan nothing showed that impeded my ability to swallow. I was scheduled for a esophogram for this, however after a few weeks of treatment with Dr. John I no longer have problems swallowing. The office is state of the art with friendly staff, and great atmosphere.

My visit today was good. I like getting adjusted because I feel like my joints more more freely. I work on a computer a lot during the day my neck tightens. The adjustments give it more of its natural movement.

I have been seeing Dr. John for over 10 yrs. He has helped me tremendously. He has spent the time with me to figure out a program that works for my condition. His office staff is friendly & efficient. I highly recommend Rhino Chiropractic & Dr. John Gehnrich.
More than 1 year agoEB
Dr. Gehnrich has a great bedside manner and can easily see when he checks my spine what is bothering me. Whenever I feel a cold coming on, I immediately visit "Dr. John" and along with some supplements and his adjustments I am feeling much better quickly. I am a regular patient, visiting at least weekly to stay healthy.
More than 1 year agoAS
My visits to Dr. John are inspiring. I may come in tired, stressed or sore, but I leave the office invigorated and ready to conquer any hurdle. Dr. John is very knowledgeable. He provides his patients with relevant facts and citations as well as links or books to learn more. Dr. John is patient and always available to meet the patient where they are in their process or chiropractic stage.
