Oleh is an anesthesiologist, resuscitator from Odesa. He's also a mountain climber. And as soon as a full-scale war began, his knowledge became truly priceless. Oleh shared his experience with rescuers. And on April 22, 2022, there was a arrival in a residential building, when it was the skills of mountain climbers-rescuers who helped save people's lives in a destroyed high-rise building.

Oleh has also organized a mobile volunteer hospital with 150 beds. His team consisted of 4 anesthesiologists and 8 surgeons. The man himself volunteered for the military enlistment office in the first days of the war, but due to his age, he was not accepted into the ranks of the Armed Forces of Ukraine. Therefore, he remained to help in the rear – both with his own hands and with the training of new personnel.
