Dr Zeilonka is a wizard of the mind body. I am in private practice rehabilitation former nurse and it is with great enthusiasm i recommend the Wizard to the general public So many options that I cannot possible ever forget about my body mind. So in this day and age if I do not come to see Dr Wizard I will be in therapy for that. I forgot to take my mind body session and it was not recommended by me. in order to obtain freedom from painful body mind ideas I regulate things by popping in to see if the master of the mind body is working or has developed a new regime. Im waiting for the next one. Its just around the corner!!!
I cannot recommend Dr. John Zielonka highly enough, he truly saved me from debilitating pain in my hand, and I’m so grateful for his expertise, compassion, and care. For months, I was struggling with persistent pain, tingling, and discomfort in my hand. Working an office job with constant typing made things worse, and I was terrified I might need surgery just to get relief. That fear was really weighing on me. From the very first session, Dr. Zielonka put me at ease. He took the time to explain exactly where the problem was coming from, not just in medical jargon, but in a way that made sense to someone like me. It wasn’t just about giving me a scan or a quick fix; he walked me through why I was feeling what I was feeling. His hydrotherapy session was an absolute game-changer. I had never tried anything like it, but the session felt incredibly healing. He was so knowledgeable and professional, and yet he made me feel totally at home, like I was in a safe space where my concerns mattered, and where real, lasting progress was possible. Remarkably, after just one session, I started feeling significantly better. The tingling started to fade, the pain eased, and I could already tell that the strategies and treatment were making a real difference. I didn’t just feel a little better, I felt like I was getting my life back. I was able to go back to my day-to-day work with confidence, without being constantly distracted by pain. Dr. Zielonka is not only technically excellent, but also deeply caring and invested in his patients. He doesn’t rush you out the door, he listens, answers your questions, and ensures you understand what’s going on. He’s kind, patient, and genuinely wants to help you heal. Because of my experience with him, I’ve already referred him to several friends and coworkers who are dealing with pain. I know they’ll benefit just as much as I did. If you’re struggling with pain, tingling, or any physical discomfort, especially related to repetitive work like typing, do yourself a favor and book an appointment with Dr. Zielonka. He made a world of difference for me, and I’m confident he can help you too!! 😊
The best $99 I've spent on my spine. I'm so glad I took advantage of their consultation offer. I learned so much about my spine during the appointment and I'm way more optimistic about recovering and returning to a normal life after treatment. Dr. Zielonka's knowledge and confidence in his ability to help people is impressive and reassuring. I'm looking forward to working with their team to heal my spine.
First time visit was an overall consult with Dr. John Zielonka. Very impressed with my entire consult as Dr. Zielonka explained very thoroughly every aspect of my X-rays and other relevant issues pertaining to my chronic lower back issues. Start robotic laser decompression sessions three times per week for two months. Expensive yes, but, quality of life is at your utmost goal and we deserve it! Look forward to starting my sessions with Dr. Zielonka and having some success in regaining my quality of life back!
My first time visiting today and I'm giving this Doctor 5 ⭐. The staff is great. Holy cow are they ever good at reminders for the appointment. I am very pleased with my intake assessment. Dr Z gave me the full rundown. He took his time to explain everything to me and answer all my questions, and email everything to me including all the x-rays and full report. I left super informed and excited for the future.
