She is part of a prominent family of voice actors, being the sister of Víctor Ugarte and Xóchitl Ugarte, and the niece of Eduardo Fonseca, who also facilitated her start in the industry. Her early training included studying acting at the Centro de Arte Dramático y Teatro and education in advertising. Her first credited role was providing the voice for Brian Cooper in the series Doctor Quinn, Medicine Woman.

Among her most recognized performances are Kasane Randall in the science fiction series Scarlet Nexus, Randgrid in the action series Record of Ragnarok, and the personified warship San Diego in Azur Lane. She also voiced Aira Misono in the fantasy romance The Saint's Magic Power is Omnipotent.

A significant period in Ugarte's career began in late 2012 when she relocated to Paris, France, which led to a hiatus from regular dubbing work. While residing in France, she worked for a firm specializing in architectural and urban visualization and debuted as a translator of French projects in 2018. Her formal return to voice acting occurred in late 2020 during the COVID-19 pandemic, when she began recording projects remotely from her home in France. Her comeback project was the anime Azur Lane for Funimation, which marked her reintegration into the industry on a regular basis. As of 2026, she has returned to reside in Mexico City. This successful return demonstrates her lasting presence and adaptability in the field of voice acting.
