Classic Hyperbarics

I bought a chamber from Mark in 2019 he was great to work with, i had not used my chamber for a while so i asked Mark how to sell and he offered to sell under Consignment for me, he picked my Chamber up in May 2025 letting me know he had buyers who were interested. I texted every few months with extremely limited response then all communication stopped. At this point it appears Mark has stolen my chamber and wil not return it. I would not recommend buying from Mark as it appears he just stole my $40,000 chamber, not cool Mark i want my chamber back.

Mark sold me a chamber a few years ago. I used the chamber for about 1 year to try to help with Lyme disease symptoms. I didn't get any relief from using it so I reached out to Mark to see if he could sell it for me. He said he would, then never followed through. I called and emailed multiple times and he does not respond. He will sell you a chamber, but don't count on any help afterward. Furthermore, a good friend of mine owned one of Marks chambers, and contacted Mark to have him sell it. Mark drove to Utah and took my friends chamber on consignment to sell it for my friend. That was 8 months ago. Mark will not return calls, texts, etc. My friend filed police reports, and Mark still has not returned any calls/texts. I think this operation is somewhat of a scam. Beware!

Our chamber has been great. We have had over 100 dives so far no issues, very happy. We have had improved vision and I have had improved sleep as well as less bathroom trips at night thanks to reduced prostate according to my Urologist. Mark has been great to work with and offers the best value in hard chambers and I looked at everything out there.

We purchased a chamber from Mark roughly two years ago and had him customize it to our particular needs. The chamber turned out great!! We had many questions in the beginning and Mark was very patient and also available. We have used this chamber no less than 150 times and it has met our expectations every time. I have contacted Mark with questions over the past two years and he has always responded. I would purchase another chamber from him with no reservation.

Purchased my Chamber and had it installed late July…I have a lung disease I am trying to resolve without having to take pills or eventually having a lung transplant. Mark has been great and very helpful with everything, answering my questions even months after my purchase. Chamber after four months has done better than I had hoped and I am looking forward to my next follow up in 6months with my doctor.
