Massoud's unwavering commitment to his community was deeply influenced by his family's upbringing in St. Nicolas Achrafieh. He was the youngest of a family of 3 brothers, Maroun and Nabil. His mother, Faride Massoud, co-founded the Lebanese Red Cross and dedicated over 50 years of her life to humanitarian work. His father, Dr. Joseph Achkar, was a doctor who modernized Geitawi Hospital, established a school for the blind and deaf, and actively participated in organizations like Caritas. He was also appointed as the first knight of the Order of Malta in Lebanon. Growing up in a household where benevolent work took center stage, Massoud inherited his parents' values of compassion and service.

Massoud was driven by a strong sense of purpose and belief in Lebanon's sovereignty and as such, strongly supported the Lebanese army. He then joined the resistance with Bachir Gemayel after the army was attacked at the war's start. He became known for his bravery in defending Achrafieh during the 100-day war. Massoud co-founded the Lebanese Forces and created the Beirut Defense Units, focused on protecting the city from outside threats. He held key roles, including coordinating efforts between different groups and authorities during the war. As internal conflicts grew, he distanced himself from all sides.

Massoud, despite his war involvement, transcended its confines. Beyond a fighter, he became a potent political activist and mediator, rivaling party machinery with limited resources. Backed by local residents, he tirelessly championed his community and fostered cross-community alliances for a brighter future.

Throughout the years, Massoud remained true to the causes he truly believed in. Some that were connected to dealing with our past, including the plight of over 17,000 disappeared during the Lebanese war. He also focused on shaping our future with a strong emphasis on social justice, advocating for essential rights like access to medication, retirement, better living conditions, and education. His commitment extended to addressing day-to-day concerns, even within municipal matters.

Devoted to Sagesse Achrafieh, Massoud's connection endured. An athletic student turned chief scout, he remained passionately engaged in the school & the clubs’ growth. He extended his commitment to the Basketball & Football club committees, contributing to their notable success during the 90s.

Massoud courageously participated in elections in Beirut I, challenging powerful political machines. He believed access to parliament was a "tool, not a means to an end." Despite three attempts in 2000, 2009, and 2018, his determination remained unwavering.

Bonded in love, Massoud married Greta AbouNader, his life long partner, and nurtured four beloved daughters: Maria, Raissa, and twins Nay and Christina. His family embodied his vision for a brighter Lebanon.

At his funeral, a daughter movingly conveyed, 'Your dedication to our nation and its people has left a profound void, but we will carry on your legacy of dignity and compassion. Proud to call you our father, we honor you.

Massoud, a beacon of service, succumbed to COVID-19 complications on January 11, 2021. During his hospitalization at LAU-Rizk, a candle walk was organized in Sassine Square for him, and prayers echoed across the nation for his recovery.

In his passing, he garnered universal acclaim for his dedicated service to the nation and his deep connection with its people. In recognition of his four decades of unwavering commitment, Massoud posthumously received the prestigious National Medal of Honour, Knight rank, in 2022.

To honor his memory, a street was named after Massoud, situated near his office in Geitawi and marking the entrance of Ashrafieh
