Customer's reviews

This was hands down the best chiropractic experience of my life. From the moment I walked in, the staff made me feel comfortable and cared for. The chiropractor took the time to really listen, explain everything clearly, and create a plan tailored to me instead of rushing into adjustments. The adjustment itself was incredible, gentle, precise, and immediately effective. I felt lighter, more relaxed, and could move with ease right away. What impressed me most was the holistic approach; I was given stretches and posture tips to help maintain the results long-term. Since my visit, I’ve noticed better sleep, more energy, and far less daily discomfort. If you’ve ever doubted chiropractic care, Dr Alessi and Dr Rennie with Alessi Functional Health will completely change your mind. ~ mariana V
I can’t recommend Dr. Rennie enough—she’s just amazing! From the moment I walked in, I felt like I was in good hands. She took the time to really understand my background and needs, which made a huge difference. It’s clear she genuinely cares about her patients. The way she explains everything makes you feel at ease, and her personalized approach has really helped me feel better. I’ve seen such improvement since I started seeing her! And I have to give a shoutout to Alanna, the office manager. She’s fantastic at working with my schedule and always makes the whole process easy and stress-free. Her friendly vibe really makes a difference. Overall, my experience with Dr. Rennie and Alanna has been awesome. If you’re looking for a chiropractor, you’ve found the right place! ~ Tyler H
Overall Great experience and very knowledgeable professional team. I noticed positive results from the very first visit. Dr. Alessi and his team put together a good custom program specifically to improve my problem areas in my neck and lower back. Dr. Alessi explained everything in a way I could understand when reviewing my x rays together on the first visit. This is not your typical Chiropractic office they don't just look to put the problem at bay they strive to correct the problem for long term relief and a better quality of life. When speaking to all team members from Dr. Alessi to his front desk and other doctor you can tell that they all have a passion for the work they do! I Highly recommend giving them a call! You will be happy you did! ~ Frank S
