August 15, 1978 - November 20, 2022


Nicole Dubois, of Lake Forest, California, died on November 20, 2022 of liver failure associated with metastatic breast cancer.  She was 44 years old.

Nicole was born on August 15, 1978 in Mission Viejo, California.  She graduated from Santa Margarita Catholic High School in 1996, and went on to attend Pitzer College for her Bachelor’s Degree where she graduated in 2000. Following her undergraduate studies, Nicole attended the University of Southern California for her Masters in (Urban) Planning and graduated in 2002.

Nicole began work at LSA Associates, Inc., in 2002, and was ultimately promoted to Principal and Managing Principal.  It was at LSA that she met the love of her life, Arthur Black. Arthur and Nicole married on July 9, 2010. They welcomed Clifton in 2012, Andrew in 2014, and Marcus in 2018.  Despite her illustrious career, Nicole’s greatest pride and joy was her family.  She believed that being a wife and mother was the greatest privilege of her life.

Nicole is survived by her loving husband and children; her parents, Vivian and Gerald Dubois of Lake Forest, California; brothers, Gerald Dubois of Lake Forest, California,; sister/niece, Elana Dubois of Lake Forest, California, and mother- and father-in-law, Marjorie and Arthur Black of Saint George, Utah.  She is also survived by many sisters- and brothers-in-law, uncles, aunts, nieces, nephews, cousins, and friends.

She was also grateful to have known brothers Daniel Greenfield of La Crescenta, California, and John Day of Santa Rosa, California, and sister, Wendy Allen of Placentia, California.
