Georgia Efthalitsides was announced as the new head volleyball coach on January 14, 2016.

In 2019, Efthalitsides led the Mavericks to 14 wins and their first ECC Tournament appearance since 2008. Mercy finished .500 or better in ECC play for the first time since 2005. Senior Imani DeBose and junior Natalia Garcia were named All-ECC selections. DeBose was named to the First Team and Garcia was tabbed an Honorable Mention recipient. 

The 2018 season saw Efthalitsides lead the Mavericks to 14 wins. The 14 wins were the most since 2005 and the six ECC wins were also the most since 2005. Senior Kaitlyn Partridge and sophomore Leilani Vazquez were named Second Team All-ECC, becoming the program's first All-Conference recipients since 2014. 

In 2017, Efthalitsides led the Mavericks to a three-win improvement over the 2016 season, nearly doubling their win total. 

Efthalitsides, a 2006 Mercy College graduate with a Bachelor's Degree in Criminal Justice and a 2013 Manhattanville College graduate with a Master's Degree in Physical Education & Sport Pedagogy, brings a wealth of experience to the position, having previously served as the head volleyball coach at The College of New Rochelle from 2009 to 2014. Efthalitsides experienced tremendous success while in New Rochelle, leading the Blue Angels to four conference championships, including two undefeated seasons in conference play in 2009 and 2014. For her successes, Efthalitsides was named Coach of the Year twice.

Efthalitsides experienced immediate success in New Rochelle, taking a 7-14 team in the year prior to her hiring and turning the Blue Angels into a 14-8 team that won a conference championship in her first season in 2009. In 2010, Efthalitsides led the Blue Angels to back-to-back conference tournament titles as they defeated St. Joseph's (Brooklyn) as the No. 2 seed.

After a two-year drought, Efthalitsides guided New Rochelle back to the winners circle in 2013, coaching the Blue Angels to an impressive 22-11 overall record as they secured their third conference championship under the leadership of Efthalitsides. In her final season as coach at New Rochelle, Efthalitsides oversaw a Blue Angels squad that went 25-8 and took home another HVIAC championship.

Prior to taking the reins at New Rochelle, Efthalitsides got her start in the college coaching ranks with a one-year stint at Nyack College as an assistant coach where she served as a technical advisor for the Warriors.

Efthalitsides' success can not only be found at the college level as she held the position of varsity head coach at The Ursuline School from 2006 to 2011 where she won two league titles and guided the team to sectionals all five years.

Efthalitsides also brings a strong administrative background to Dobbs Ferry, having served as the Senior Women Administrator (SWA) and Coordinator of Intramurals and Recreation at The College of New Rochelle. In her role, Efthalitsides oversaw the Wellness Center on campus, coordinated intramural programs and acted as the SAAC advisor. Efthalitsides also served as the softball coach and was responsible for many of the day-to-day operations of the athletic department.

Efthalitsides currently also serves as the head coach and club director of Alpha Gamma Juniors Volleyball Club in Sleepy Hollow where she oversees all the day-to-day operations of the program.
