At first he and Morgan performed in New York, and later in Paris, and elsewhere in Europe and Asia, including Leningrad, Morocco, and throughout France, with a grand finale at the annual arts festival in Avignon.

He wrote of contrasts between the hectic life of performing in New York and Paris and evening walks in the countryside of Southern France, where it was "so easy to breath the joie de vivre and forget that there might be any destination or goal beyond just being itself".

[6][7] While living in southern France, Koob and Morgan conceived of developing a retreat center in an old monastery where they "could take a centuries long tradition and give it a modern twist to celebrate the arts, nature, health and spirit".

He helped Morgan found, manage, and fund Dance O Hawai'i, which performed throughout the Islands' communities and schools, as well as in the Asia Pacific region.

He furthered the legacy of Kalani's co-founder by dedicating a large studio – popular for weekly classes, ecstatic dances, and community gatherings – the Earnest Morgan Arts eXuberance (EMAX) pavilion.

[5][6][7][10] Lester John ("LJ") Bates III was appointed as Kalani's Executive Director in November 2012, and after a period of transition Koob officially retired in July 2013.

Koob's philosophy is expressed in Kalani's Mission "to provide a fun, safe and educational retreat village which encourages ALOHA love for life in each person's own deepest way through participation in abundant nature, culture and wellness experiences.

Kalani also sponsors special events; hosts diverse residential retreats and workshops; provides lodging and meals for guests; oversees volunteer, sabbatical, and visiting artist education programs; and houses a sustainable community of residents in an eco-village.

E Ho Mai expresses Koob's philosophy of aloha as a way of life:[5][14] We were north, south, east and west our working week and our days of rest our talk, our dance our noon, our midnight We believed that love would last forever and we were right.
