The adventurous couple has been together since high school but only began pursuing climbing in 2015.
Lehmann began learning climbing techniques by watching YouTube and passed on his knowledge to Unger.
However, due to the extreme conditions surrounding Everest and other tall mountains, they sought out other solutions.
We were really proud of ourselves.
However, he has not been seen since, and a search mission was abandoned on June 6.
Of course, we know that mountain climbing comes with risks, Unger adds.
But it happened to our friend and our Deaf community, and its not easy for us.
Lehmann and Unger are now looking to make more history for the Deaf community.
Their next goal is to complete all Seven Summits, which are the highest mountains on each continent.
So far, the couple has already summitted Everest, Kilimanjaro, Aconagua, and Denali.
Its available for people with disabilities.
