My daughter was diagnosed with ADD 2 years ago. Her father and I really struggled on the idea of giving her a “magic pill” to control her ADD symptoms. We tried to do everything from extra help & tutoring to keep her off of the medications. Finally the principal sat us down & explained to us that our daughter was struggling and we needed to go with the concerta her doctor had prescribed. She was put on a high dose of the medication. While being on the medicine she did do better at school but she also had a “zombie” type appearance and lost her personality. After talking to Dr. Voortmann about how unhappy I was about putting my daughter on the concerta. We explored the different routes we could take with the NRT program. Since my daughter has been on the NRT and chiropractic program, her mental focus has improved dramatically and she has gone down to the lowest dose available on the concerta. It has been an amazing transformation!

Customer Testimonials

Hi, Just had to report that I had a FANTASTIC day, feeling the greatest ever! Not this desire to EAT everything I see, NO desire or want to feeling at all today, WOW what a GREAT feeling, what a GREAT day! Wondering why I can not have these days every day! I desire to have many many more days like this...also, had my hair cut yesterday, my hairdresser is amazed how thick those new dark hairs are coming in and there seems to be more and more each time, yippy! She is wondering will all my white hair turn back to my dark brown or maybe just be a salt and pepper look, and how long might this take to make a complete change? She is in awe of this process, as I am too! Today just encourages me that I will get to my pot of gold, losing weight and being this healthy person. I thank God for you and what you have done for me. See you Thursday! Abundant Blessings.

Restless legs kept me up at night. I could only ride in a car for two hours. The legs were just annoying, I couldn’t sit still, kind of hurt, but really just annoying. I had to take Advil to go to a three hour movie before legs started acting up around 9:30 pm every night. Exercise and Advil helped sometimes. Now I can sleep comfortably most of the time. If I forget minerals my legs tell me so. I can sit on the floor and I get up easier now.

I am pregnant and was suffering from nausea and vomiting and low energy. After 10 days - I haven’t vomited in 3 days, my nausea has improved a lot and my energy level is increasing.

“Before I came into Dr. Voortmann, I had high blood sugars due to type I diabetes, chronic fatigue, brain fog, intense sugar cravings and many other conditions that overwhelmed me and my health. Several weeks later after treatment my sugar cravings have gone down and my sugar levels have gone down 18 points and stabilized! I have more energy to keep up with my toddler daughter and I’m looking forward to my health improving even more! I have already seen improvements just in the last week”, she concluded.

“After many years of playing golf, baseball, basketball and everything else associated with sports, I found myself unable to walk without the most excruciating pain I had ever experienced in my life. I had spent time prior to this, visiting doctors and chiropractors all over the Midwest , attempting to ease the pain in my lower back. I did, finally, get some temporary relief with shots directly into the spinal cord. However, these would only help for about 30 days. Back surgery to fuse vertebra together proved to be of no help.

A year after my surgery, my wife also and some back discomfort. She made an appointment with Dr. Voortmann in Clear Lake . During her visit, she discovered that the Dr. had, had some success in treating people with spinal fusions, such as I had done. Within minutes of hearing this, I made an appointment and 4 weeks of treatment later I had very little pain left to cope with. Six to 8 weeks later I had no pain at all! Thank you Dr. Voortmann for a life without back problem, how great is that!!!

From Our Website

Our mission is to educate and adjust as many families as possible toward optimal health through natural, corrective Chiropractic care. This web site is an effort to clarify our procedures and answer some questions you may have about our office. Corrective Chiropractic care addresses the total body regardless of symptoms or pain. While pain is an indicator of a problem, a nervous system problem may be present without a pain response. Pain is generally the last symptom to be revealed and the first to go away.

When you enter the office, you will be greeted by a friendly, courteous staff that will take your important medical information and will guide you through our office. Please bring any pertinent information such as MRI reports or X-rays. A thorough chiropractic, orthopedic and neurological examination will be performed to help diagnose your condition. X-rays may be taken to help rule out aggravating factors. If needed, other diagnostic tests may be ordered. Once your doctor has reviewed the radiographs and their exam findings, you will be given a full report of what can be done to ensure the improvement of your condition.
