I have been struggling with Lupus for the past 17 years.There have only been 2 periods of time that whole time that its been manageable and just sorta there but not awful. Thr first time was when I was under the care of a chiropractor who had since retired. For the past 6 years I have tried almost every chiropractic office in McHenry county with extremely limited results. Until I found A to Z. Lupus is never pain free but I have been debilitating pain free since beginning treatments there. When I say I owe this to Dr. Zach I'm being serious - I'm doing things I used to be afraid of - like doing squats at Cross Kicks that are at my max - with the philosophy that "thats ok Dr Zach will fix it" - my point in this very long winded post - if you're looking for a chiropractor A TO Z is where you should be, if you have a chiropractor & don't feel amazing, you need to switch, if you've never been to a chiropractor - give it a try." My daughter who had Ankolosing Spondylitis- a debilitating disease also treats with Dr Zach - the fact that is mobile is a testament to his ability, skills & knowledge. read more

Dr Zach Ryan is a wonderful person & a great chiropractor. He has helped me with pain I experience from chronic Lyme disease. His adjustments are never "bone crackers" (something I've experienced with others in this field). Dr. Zach is sensitive to his patients' pain & is very gifted in making gentle adjustments. Abby who does massages for this practice is also a lovely person. She too is sensitive to a patient's pain & communicates well during her therapeutic massages. A massage with Abby is a perfect complement to Dr. Zach's adjustments. I highly recommend this practice to anyone who is in pain. These folks can help you feel better as they have helped me. read more

Wonderful! I wish that we could rate them even higher. They are currently not only helping me, but they are helping my 83 year old mother and y 13 year daughter who suffers with JRA. Dr. Ryan has relieved me of so much of my neck pain. It is so wonderful to have regained range of motion since my car accident. My daughter has experienced relief we never thought possible with her JRA. My mom who has a lot of trouble walking because of arthritis in her lower back is noticing a difference as well. Dr. Ryan not only treats you and your symptoms, he teaches you stretches and exercises to do on your own to make yourself better. This is an exceptional practice! read more

Dr Ryan performed quite the adjustment on me before I make the move out of state. It's been great for the short amount of time that I had having him adjusting my back. I wish he had an office up north so I could continue getting his 5 star treatment but I hope to get some great recommendations for my new residence in Wisconsin. He has been the best chiropractor I've ever had and I highly....yes highly recommended him for any and all back adjustment that u would need. He is so understanding of ur needs and so well trained that after one visit u will never go anywhere else. Thanks again Dr Ryan for all u have done for me and wish u all the best!!!!! read more

I had gone to the centegra immedia care with pain in my hip shooting down to the top of my knee. Had a xray all good there just gave me meloxicam to reduce inflammation. Saw Dr Zach Thursday afternoon n he stretched n manipulated back hip n leg muscles I iced 20 min each hour n did my tens unit on my hip with his guidance. Fanatastic!!! I could sleep at night without pain when I rolled over, woke up without being stiff n sore n had no shooting pain in the afternoon. HUGE difference!! A to Z Chiropractic is the natural care with results that truly make a difference. The future of healthcare! Dr Zach has definitely gained a new patient. read more

Dr. Zach and his massage therapist Katie, are definitely the "dynamic duo". No matter how you feel when you walk in there, you feel 100% better when you walk out. They both take the time to listen first, and then spend the time to make you better. Dr Zach does not just "crack your back and neck", and then send you on your way. He spends time with you and does therapy as well. So if you think you don't like chiropractors, then you definitely need to see Zach.....and then have Katie give you an amazing massage that will transcend you. It's definitely a great experience, that you will not get with any other chiropractic office read more

I have now been getting regular chiropractic treatments from Dr. Zach for 15 months. I am highly impressed with the breadth of his knowledge and understanding of a wide variety of musculoskeletal problems. As I said in an earlier review, I have been to well over 20 chiropractors. Dr. Zach is as good as they get. His integrative approach involves applying knowledge from a variety of sources and he never fails to help with whatever issues I bring to him. We are lucky to have someone of his talent, caliber, and competence in our area. And don't tell him I said this, but he is a pretty funny guy as well. read more

I've been to my fair share of chiropractors over the years and while I thought my last one was really good, I just wasn't getting any relief from extreme tightness. Dr. Zach may just be the answer! I had a chiropractor years ago who was wonderful, and not only adjusted me but worked on my muscle tightness as well as gave me exercises to help strengthen. Ever since he moved away I hadn't found one that would address the tightness, just a quick adjustment...until today! I finally see hope again and can't wait to see where I am a couple months down the road. Thanks Dr. Zach!! read more

Dr. Zach was amazing and has a great sense of humor! Aside from the initial reasons I sought out chiropractic care, he answered other, unrelated questions to help me in my overall health. I was comfortable the entire time. New experiences can be intimidating as it seems you never know what type of care you will receive, however, you can be sure the experiences at A to Z will exceed your expectations. I appreciate how welcoming he was to myself and my daughter. I highly recommend A to Z Chiropractic! read more

A-Z is the best!! I will always refer all of my family and friends there. Karen Owens is one of the staff members I have to thank in particular. She was raving about A-Z since the day we met, and boy was she right! She's a person that always makes sure you feel heard and is so understanding. I recommend is you have any questions or concerns talking with Karen first. She will make sure you get the care you need asap, and will also follow up asking for your doing post treatments. read more

I have been a patient here since they opened this office in Crystal Lake. It is a great facility and the chiropractic care and knowledge is outstanding. I see the doctor regularly for adjustments. I have experienced great physical relief after a session with Dr. Zach. I highly recommend A to Z. I have recently added some massage therapy to my care routine at A to Z. Abby is excellent. read more

Doc Zac really is the best! He always makes time for me when I'm in need of being squeezed into his schedule, and he always goes above and beyond to make sure everything is back to where its supposed to be! He has great bedside manner and I always leave feeling better physically and mentally. I would never hesitate to recommend A to Z Chiropractic. They are like one of the family! read more

Doctor Ryan is one of the best chiropractors I've seen. He is very knowledgeable and addresses every concern with expertise and professionalism. His massage therapist, Abby, is excellent as well. The office is conveniently located and spacious and appointments are easy to arrange via phone or email. I highly recommend this practice for chiropractic and massage therapy needs. read more

Dr. Zach and Abby are wonderful and knowledgeable folk!! I battled cancer in my left foot for 2.5 years and had to use a knee walker for all that time. The device ended up screwing up my lower back causing horrid pain. These two not only helped me get back on my feet but also helped to rid me of the pain and realigned my back. I would HIGHLY recommend going to these guys!!! read more

Dr. Zach is helping me through a back injury that is causing severe pain in my sciatic nerve. He can be trusted to know what he needs to do to as the professional, and also, what I need to do as the patient. Although going through this is somewhat uncomfortable, his knowledge and guidance are always right on. I have no doubt relief will be here soon. Thanks Dr. Zach! read more

Awesome place! Incredibly friendly, easy going, understanding, and knowledgeable. I've been going to A to Z for about six months, and have felt much better after receiving treatment than when I entered the building every single time. I've received adjustments as well as massages, and both have helped immensely in my recovery. Cannot speak highly enough of A to Z! read more

I always experience kindness and caring from Dr. Zach and his entire staff. The treatments I receive are always thorough and specific to my needs. Dr. Zach takes time to answer any questions I have about my condition and treatment. He's helped several family members from grandkids to grandparents. We feel very thankful. Quality care like this is hard to find! read more

I do not know what I would do without A to Z Chiropractic. I suffer from horrible seasonal allergies and Dr. Zach Ryan's adjustments are the only thing that helps me with relief. He has also been able to adjust my husband's elbow that he has not been able to move in years. We highly recommend A to Z Chiropractic! Karen Owens read more

I couldn't be more pleased with Dr. Zach. He is very concerned for his patients, always calling and following up the next day to see how they feel. He goes out of his way. He is personable and caring. I never write reccommendations but he certainly deserves the highest of remarks. We need more doctors like him! read more
