Adventure Consultants report on summits and people by 2016:
Da Jangbu Sherpa, Nepal, 13 summits
Pemba Chhoti Sherpa, Nepal, 11 summit
Kami Rita Sherpa, Nepal, 14 summits
Purba Chhoter Sherpa (Ang Jangbu), 8 summits
Chhewang Dorji Sherpa, Nepal, 9 summits
Chhiring (Tsering) Namgel Sherpa, Nepal, 4 summits
Da Thuk Bhote, Nepal, 3 summits

It can be hard to determine who is who sometimes, as there are some similar names. For example in 2013 two different Kami Rita Sherpa high-altitude workers summited with different guide firms. Nepal may not issue summit certificates to Nepali who don't buy a permit. One problem firms must contend with is summit fraud attempts. See also
