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.

    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

    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, it's 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...😊

    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. I've seen a number of chiropractors over the years, but I continue to see Dr. Fredrick whenever my back is acting up.

    I've been going to Dr. Fredrick for years!! He's very thorough and takes time to get to know his patients. He has helped me multiple times to recover from back issues!! I've 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!!

    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.

    Doctor Fredrick has the hands of a healer. He has helped me over the years no matter what the problem has been. I've had 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 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. 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 he's the absolute best! I highly recommend him!!!
