Clarence Mamaril is our interim Parish Secretary. Clarence joined St. Isabella's Parish in 2001 as a cantor and guitarist, 
and has served in several different ministries over the years, primarily music and youth ministry. His present ministerial responsibilities include preparing our 
Parish Bulletin, church and parish center scheduling, and assisting our high school & adult youth ministry volunteers. Clarence has been happily married 
to his wife for over 23 years, and they have 3 daughters and 1 grandson. A graduate of Santa Clara University and Santa Clara University School of Law, he is 
also an attorney, primarily in Immigration law, and a Parks & Community Services Commissioner for the City of American Canyon.


Shane Graham is our Co-Director for PYC high school ministry.  His entire life's religious experience has centered around St. Isabellas.  He attended mass here as a child and was a graduate of St. Isabella's school.  While in high school at Terra Linda, he discovered his love for PYC as a participant for 4 years and an officer for 2 years.  After graduating from College of Marin and Dominican College, Shane was sure about only one thing for his future.....He wanted to be part of PYC. He wanted to give back to the program that helped him get through the difficult & awkward years of high school.  In 2008, Shane volunteered as adult faculty and was asked by then director, Clarence Mamaril, to become head of PYC liturgies. Shane's creativity and love for this program is evident in all aspects of his ministry. He was asked to become Director of PYC in 2014.
