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.

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!

I have been down for almost a week due to the pain in my lower back. This morning the doctor gave me my adjustment but then I saw their clinical massage therapist named Melissa. And now I’m up walking around my house. That lady is a miracle worker. I’ve cried every day from pain for the last 4 days and today I cried because I was finally able to lean forward to wash both my hands in the sink at the same time without pain. Crazy and tmi I know. But we take for granted the little every day things. If you’re looking for a spa like easy massage this isn’t it. If you’re looking for results and actually getting those tough muscles worked out so you can start living again… this is your spot!!!! Thank you so much and I look forward to seeing y’all again.
