While an Education and Media Specialist at the United Nations,[7] Arnold created multi-platform programming with A-list celebrities like Jay-Z[8] and Angelina Jolie.

Arnold's most high profile show, “Exiled!”,[9] was predicated on uprooting sheltered, affluent American teenagers to live with indigenous communities throughout Kenya, Thailand, Panama, Namibia, Brazil, India, Vanuatu, Norway, and Peru.

[17] This led to an Executive Order signed by the Trump Administration[18] that proposed a new HHS rule[19] that received bi-partisan support from the Senate Finance Committee,[20] the House Committee on Oversight and Reform,[21] Senator Warren (D-MA), Blumenthal (D-CT),[22] Grassley (R-IA), and Young (R-IN).

[23] Arnold was a featured presenter at the White House Organ Donation Summit, which also included major partnership announcements with Facebook, Twitter, Instagram, and NASA, and a $300 million bioengineering investment from the United States Department of Defense.

[28] Arnold was a surrogate for the Biden 2020 campaign,[29] continues to serve as a political and social voice on Fox News Channel, MSNBC,[30] as well as international outlets.

ORGANIZE's work to modernize the living donation technology infrastructure was also featured on the May 14th, 2017 episode of HBO's Last Week Tonight with John Oliver.

[51] Notably, an ESPN article recounts a story of Arnold negotiating with the Boston Red Sox during the 15th hour of labor during her first pregnancy.

[52] Arnold married social entrepreneur Jeremy Goldberg, President of LeagueApps, at the Seeds of Peace Camp in Maine in 2008.
