Hyperbaric Oxygen Therapy (HBOT) can help you reach new heights in health, naturally, using 100% pure oxygen.
Not all equipment is created equal. No zip-up HBOT at Rainier Hyperbaric. Rainier Hyperbaric offers state of the art Sechrist hard shell monoplace chambers for individualized hyperbaric oxygen therapy sessions to increase the body’s ability to fight infections and improve the rate of healing.
This noninvasive and painless treatment can help those who suffer from chronic illness, injuries, infection, PTSD, and catastrophic events such as strokes or brain injuries. HBOT treatments involve increasing the atmospheric pressure in 100% pure oxygen inside a pressurized chamber. Tissues become saturated with oxygen, which promotes healing that cannot be achieved with any other therapy.
A typical series includes 60-minute sessions, 4-5 days per week for a minimum of 30 days. Depending on the severity of the issue and the body’s response to HBOT, the treatment period may be longer.
Visit our About HBOT page to read how HBOT is used to treat various debilitating injuries and conditions.
We are excited to announce that Rainier Hyperbaric is now officially recognized as a Certified Woman Owned Business by the Washington State Office of Minority & Women’s Business Enterprises

Love this place !Posted on Michelle CorderoMay 9, 2026Trustindex verifies that the original source of the review is Google. Jack and Michelle are so amazing! I have been trying to get my mom a referral for HBOT and her insurance was taking a long time. I had been looking for a business that has the right equipent so that my mom could get pure oxygen and the right amount of pressure. I tried many locations that only had mild chambers that were unable to do what Rainier Hyperbaric can do. My mom was diagnosed with melanoma that spread to her lung and her brain in 2023. She immediately went through 10 rounds of whole brain radiation. Due to this treatment, she started to cognitively decline. I found out about the possibilities of HBOT and that it was a possible treatment for post radiation damage. She is on her 12th treatment of 20 and she is already improving cognitively. She has more energy and finally has hope that she will be able to live a more normal life. Jack and Michelle together as a team are so welcoming, helpful, and understanding. They quickly added us to the schedule and have been such a warm and kind place for my mom to get this treatment. I am eternally thankful for the guidance and kindness that they have shown my mom and my entire family. I am still working on a referral so that insurance will cover the rest of the treatments needed. However, there is no one else in the area that offers this level of treatment for the price. I will recommend them to anyone I know that is in need of this treatment!Posted on Tereasa TapiaMay 9, 2026Trustindex verifies that the original source of the review is Google. We are about halfway through our 20 session allotment and are seeing great improvements to overall health. I can’t say enough about how wonderful hyperbaric oxygen therapy has been. I see total improvement overall - far surpassing what we originally expected. Jack and the team are so helpful, caring and took the time to explain the entire process to us. They offer affordable options for all situations. I highly recommend this therapy to anyone looking to improve cognitive abilities, wound healing, and just overall benefit to quality of life!Posted on Jason ThomasApril 12, 2026Trustindex verifies that the original source of the review is Google.

Adding Hyperbaric to my healing process has sped up my recovery time by at least half!! There new chambers are so much roomier and the atmosphere they have created at Rainier Hyoerbaric is 5 star. I would recommend this to anyone going through a healing journey! 🩷Posted on Lenna ShepardDecember 31, 2025Trustindex verifies that the original source of the review is Google.
