Halcyon Life's website describes an HBOT clinic in New York City offering hyperbaric oxygen therapy for Long COVID, Lyme disease, neurology, concussion and TBI, migraine, and multiple sclerosis. The chamber is a custom-built, modified 2.0 ATA hard-shell unit with protocol-ready configurations. Olympic gold medalist and world champion wrestler Helen Louise Maroulis is featured as a testimonial — she discovered HBOT after a PTSD diagnosis from multiple traumatic brain injuries in wrestling, calling it 'a game changer for not only my athletic performance but also my overall health and wellness.' The site offers extensive educational resources including 'What is HBOT?', scientific references, safety information, HBOT vs conventional methods comparisons, and session preparation guidance. Personal, caring, and reliable service with package pricing.
