Be Careful!He validated my insurance before I seen him and as a good faith I signed all the usual papers . He got Insurance payment and my daily payments. I stopped going to him because see no benefit.Now 4 years later He is asking more money saying insurance not paid him enough. going crazy with Collections and lawsuits for money.When we seen him he always told us no worries we will take care of insurance. He is a liar and extremely greedy person. Be careful!

Dr Fredrick gave me desperately needed relief from my migraines and neck pain. I was finally able to sleep after my first adjustment. He gave me a thorough physical exam and showed me why I was experiencing this pain. Then he discussed a treatment plan with me. Tiana, his receptionist, graciously took my appointment with very little notice.

Dr.Fredrick have helped me in 2 different occasion. Thank god for him and his office he got me up an running. As a single mom every minute is very important to us and work even more. He help me reach my goals and got me up and running quick. I appreciate everything he has done and his staff are wonderful. I would recommend anyone to his office. Thank you Dr. Fredrick.

Dr. Mark Fredrick extends the utmost care and professionalism to all patients. I have been going to Dr. Fredrick for several years and have received nothing but great care from him and his team. From my soccer days, to getting therapy and treatment for my knee, and, most recently my shoulder, or for the much needed back adjustments, I know I can count on his expertise to heal me! With no doubt hes the absolute best! I highly recommend him!!!

He was highly recommended by my primary care physician, I needed therapy for my broken wrist and was also having a lot of pain on my left knee to the point I couldn’t walk, but in 5 visits I feel better, the pain is gone and I can perform my daily activities, he is the best, I love that he not only adjusts but also massages where the pain is, He charges a reasonable price, HIGHLY RECOMMEND HIM

Doctor Fredrick has the hands of a healer. He has helped me over the years no matter what the problem has been. Ive has so much trouble with tension in my neck and back lately and he has been a lifesaver! I recommend him to everyone I know.

Dr. Fredrick is an extraordinary healer. I have been going to him for over 26 years and have referred many now happy clients with their chiropractic needs. You will be wowed with his ability to assess and heal. From the office professionals of his entire team to his holistic remedies for overall health issues, you will be totally satisfied.

Highly recommend Dr Fredrick, and also his staff. I started seeing him after a car accident. He is very professional, and highly skilled. Also his massage therapist, Patty, is fantastic. Ive seen a number of chiropractors over the years, but I continue to see Dr. Fredrick whenever my back is acting up.

I sought out ALL KINDS of treatments for my coccydynia (coccyx pain) for 2.5 years (physical therapy, medications, specialist, including another chiropractor) to no avail. The pain was daily and overwhelming. I read a book about coccyx injuries and then by Gods grace, ended up at Fredrick Chiropractic . Everything I read in this book, Dr. Fredrick knew about and did! After just 6 treatments, I was pain free for the first time in years! This man knows what he is doing! He has a kind heart and really appears to enjoy helping others with their overall health! I am so very happy! I have recommended many friends to go to Fredrick Chiropractic! Thank you so much Dr. Fredrick and staff! Diane Arndt

Ive been going to Dr. Fredrick for years!! Hes very thorough and takes time to get to know his patients. He has helped me multiple times to recover from back issues!! Ive been going to him for over 20 years and will continue to go to him! I would and do recommend him. His staff is very friendly too!! Patty gives great massages too!!

I went into his office after I had a terrible fall and thought I made need surgery but after 2 weeks I am feeling awesome thanks to his care and they have an awesome staff waiting to help you they really care ! So Thank You so much

Wonderful place. Highly recommend it. Dr. Fredrick and his staff are so caring. My back is so much better, on the detox plan. Lost 24 pounds in 6 weeks. They are like family.

I have been going to see Dr. Fredrick for a few years now. I am always pleased with my care. I received massages this time and they were very relaxing as well.

Coach-Bob Carey Dr. Mark Fredrick is by far the most comprehensive and competent Chiropractor that I and my wife, have been fortunate to visit. not only is he extremely through, he has great integrity. you could not find a better all around general health facility or clinic anywhere!

Dr. Mark is amazing and gives extremely thorough adjustments! When I get off of the exam table my whole body feels relief from my head to my toes.I sit at a desk all day and it can be very stressful on my neck and lower back. I try to get in at least once a week for an adjustment and some stim treatment, its so worth it. Thanks Dr. Mark!

There is so much to say about Dr. Frederick. So for 10 years Ive been seeking Chiropractic care. Some were ok some were not. My first visit I was Very impressed. Dr. Frederick did a complete exam unlike anything any Chiropractor Ive seen including xrays and , measurements and some orthopedic equipment did some kinda work up on my feet. WOW.. Then I had an Amazing massage by Patti. I bought some Awesome Protein powder, and on my second visit I truly felt a difference in my body, my pain and range of motion was better. I am very excited about Dr. Frank and his staff because I really feel as though He gives care to his patients just as he would family. I recommend his pratice 100 percent. Finally I can see the rainbow at the end of the tunnel. Who knew my relief was always 3 mins from my house...😊

I am no longer in pain and did not need to take any medication! Do see Dr. Fredrick. Great Staff. He is also Dr. OZ Certified!

I love Dr. Fredrick!!!!! He is very good at his job and cares allot about his patients and for that I give him a A+

Dr Mark performed therapy on a severely injured hamstring. Within weeks I was running again. The staff is great. All around great experience.

When I first came in I was crying and hurting real bad but after several visits I can now do things that I havent been able to do in years. I can mop the floors and help out in church and do things i couldnt do before. Thank you so much Dr. Fredrick! We have so much fun here

Dr. Fredrick is an outstanding chiropractor and I have and continue to recommend his practice to anyone needing care from head to foot!

I came in and I could barely walk or breathe after a car accident and Dr. Mark has helped tremendously. Staff is friendly and wonderful and I would highly recommend anyone in pain to come check him out.

Best kept secret in Gurnee! Pain gone and I cant believe how well I can move around. I had therapies, drugs and they didnt work, this did.

He takes the time to get to know what is causing the issue and works hard on correcting it.

Excellent care from a an expert practitioner.

Dr Frederick always has the solution to fix your pain!
