Testimonials

“Dr. Krystosik has helped me tremendously. I was experiencing severe digestive symptoms that were controlling my life and preventing me from doing things I needed and wanted to do. Dr. K helped me identify the underlying cause of my symptoms, and now I am feeling great! My regular doctor couldn't help me and wanted to send me to a gastroenterologist. Dr. K was able to help me safely and naturally without the use of medication. It is truly a complete night-and-day difference from where I started. I highly recommend seeing Dr. Krystosik to keep you healthy!”

“Dr. Krystosik has been instrumental in improving my health. I was battling severe digestive issues that significantly disrupted my daily life. With Dr. Krystosik's help, I identified the root cause of my symptoms and have since experienced a remarkable turnaround. Unlike my regular doctor, who suggested consulting a gastroenterologist and prescribing medication, Dr. Krystosik offered a safe, natural solution. The difference in my health now, compared to when I started, is like night and day. I highly recommend Dr. Krystosik to anyone seeking to maintain good health.”

“I first started visiting Dr Krystosik over 10 years ago. Both my father and grandfather passed away from cancer, and I wanted to be proactive in addressing any potential genetic tendencies in my family. Dr Krystosik has utilized various tests to determine delayed food allergies and deficiencies within my intestinal system. The results of these tests allowed Dr Krystosik to coach me toward better lifelong health. I have made the necessary adjustments to address the deficiencies that were discovered, and I follow his guidance on proper nutrition, which has allowed me to lead a very active life. Since I have been visiting Dr. Krystosik I now consider him to be my family doctor!”

“Dr. Krystosik is a very caring doctor who genuinely cares about his patient's health concerns. He always gives me clear, quick answers and educated advice on solutions that work best for my body. I have seen several doctors in the past (including holistic), and he is the only one who found an underlying cause through testing. I have Crohn’s disease and constant flare-ups. Dr. Krystosik put me on a natural regime along with good, clean diet instructions. It’s been just over a month, and so far, my extreme bloating and abdominal discomfort have vanished, and my bathroom habits are regular again. I have a long path to healing, but so far, so good. I am confident that he can help me stay on my path to healing my gut once and for all. Thank you!”

“I’ve had a total recovery from my stomach problems with Dr. Krystosik’s care!! I suffered for 5 years with severe stomach symptoms, and traditional doctors could do nothing for me! I am now 100% better. So thankful! He also did great wonders for the severe back spasms I had. He is very knowledgeable and can help you with any symptoms you may have in any area of your body. Totally Worth it!!! Working in healthcare myself, I can confidently recommend him.”

“Dr. Krystosik is the best. He always makes time to call when I have a problem, gets me into the office on short notice, and has healed me naturally without harmful medications. Dr. J changed my life, and I don't know what I would do without him!”

Jacqueline W.

“I came in with IBS-like symptoms that were ruining my life. It was chronic for over a year and I’m only 29, regular MDs told me it’s just something I’ll have to manage and gave me meds that might have made it worse! Nausea, bloating, and fatigue were the main symptoms every day. I happened to stumble upon Dr. Krystosik's office while considering an alternative approach, and I thank God that I found this place! Dr. K has a masterful approach to diagnosis and nutrition, and it’s all about the gut and what we are eating! Do the tests he recommends, they will pinpoint you’re issues with high accuracy, you won’t get these at the hospital (I know from experience). Dr. K will tailor a diet and medicine regimen specific to you. What he’s done for me has already worked in just 3 weeks! It’s a miracle that most of my symptoms are already gone!”
