I’m so thankful to have found Peak Health! I became very sick with Chronic Lyme Disease last year and have been working with them for about 4 months now. I’ve been seeing Haley Young and Dr. Lazzell, and they’ve both been absolutely amazing. They truly listen, advocate for me, and always offer helpful solutions to manage my symptoms. They’ve also been great about working with my financial limitations, which has made a big difference. I’ve been getting IV ozone therapy as part of my treatment plan—nurse Vanessa is the best! The clinic itself is clean, welcoming, and helps ease any anxiety I might have. I also really enjoy their social media, emails, and blog posts—they’re always well done and full of helpful information. Peak Health is such a well-run clinic. I can’t say enough good things and always recommend them to friends, family, or anyone navigating Lyme Disease treatment.
I’ve been on a long and challenging journey dealing with Lyme disease, mold toxicity, and heavy metal detox. After visiting numerous offices and trying countless protocols over the years, nothing truly clicked—until I found Peak Institute. The team at Peak is truly exceptional. Their attention to detail is unmatched, and what sets them apart is their ability to look at the full picture rather than just isolated symptoms. They approach healing with a wide-ranging perspective, integrating multiple disciplines and innovative treatments in a way that feels both grounded and deeply personalized. Every appointment is punctual, and the environment is warm, professional, and genuinely caring. From the moment you walk in, you feel seen, heard, and supported—not just as a patient, but as a whole person. Thanks to Peak Institute, I’m finally experiencing real, sustainable progress in my healing journey. I’m incredibly grateful for their expertise, compassion, and the hope they’ve restored in my life. If you’re looking for a team that truly understands complex, chronic conditions and how to treat them at the root—this is the place.
Dr.Montalvo and her staff are amazing! Her nurse Vanessa is so compassionate in providing patient care. They really address your health needs I absolutely recommend Peak Health Institute for all your health and wellness needs.
