Gigliello had served as a King's assistant for four seasons before being promoted to head coach. In her first season, Gigliello took over a program which had won only four games in 1993 and promptly doubled the squad's victories in her first season. Vast improvement continued into the 1995 campaign as Gigliello led the Lady Monarchs to a 14-17 record, narrowly missing the MAC playoffs in the process.
In 1996, Gigliello led King's to its first-ever post-season playoff berth as the team advanced to the MAC "Final Four". In 1997, Gigliello coached King's to the program's first-ever 20-win campaign. After another 20-plus win campaign in 1998, Gigliello led the Lady Monarchs to their first post-season championship ever when the Lady Monarchs captured the 1999 Eastern College Athletic Conference Southern Region championship.
In 2000, Gigliello led King's to its finest season ever when the Lady Monarchs captured the MAC Freedom League championship, the MAC overall title, and advanced to the NCAA Division III National Tournament for the first time in school history. After guiding King's to a program best 38-6 mark, Gigliello was named MAC Freedom "Coach of the Year."
The 2001 season produced a third conference title, and second NCAA tournament appearance. The team finished the season with their 5th consecutive 20 win campaign, going 28-12. In 2002, King's won its third straight MAC Freedom championship and advanced to the NCAA tournament. The Lady Monarchs would drop a 2-0 heartbreaker to eventual national champion Ithaca while concluding a stellar 36-10-1 campaign.
The 2003 season resulted in a fourth straight MAC Freedom title and another trip to the national tournament as the Monarchs capped a 24-11 season. The 2004 season resulted in a fifth straight MAC Freedom title and another trip to the national tournament as the Monarchs capped a 39-10 season.
The 2005 season produced even more success as the team went 34-12, winning a 6th consecutive MAC Freedom title and advancing to within one game of the college world series. The 2006 squad finished second in the Freedom Conference Tournament but earned a seventh straight NCAA national tournament berth while concluding an outstanding 38-9 campaign.
In 2007, the Lady Monarchs regained their throne, finishing the year at 34-9, winning their seventh Freedom Conference title in eight years, and earning an eighth straight berth in the NCAA national tournament. After a third-place in 2008, the Lady Monarchs again won the Freedom title and gained a ninth berth into the NCAA national tourney. Gigliello was honored with her third Freedom Conference "Coach of the Year" award.
Since Gigliello took over the program in 1994, a total of 79 Lady Monarch players have been named to the MAC All-Star Team while 31 others have been named NCAA East Regional All-Americans.
King's teams have also excelled off the field as 78 Lady Monarchs have been named to the MAC All-Academic team and 41 to the National Fastpitch Coaches Association All-Academic team.
