Amy Diffley


Executive Director

Amy joined Big Sister League of San Diego in July 2019. She brings more than eight years of insight and experience to her position at BSL. Before coming to BSL, Amy worked in executive leadership with Community Care Management Corp. in Northern California. Amy has worked with many different populations over the years including seniors, individuals living with HIV/AIDS and developmentally and intellectually delayed persons.

Amy enjoys interacting with the residents of both houses and staff and looks forward to advancing BSL's mission while focusing on its core values of providing supportive housing services to our residents. Amy has spearheaded new activities to help residents feel engaged, comfortable, and relevant, including initiating a relationship with Frosted Faces Foundation to bring a senior dog into the home to provide support for the residents.

Since coming to BSL, Amy has restructured and implemented new policies and procedures to ensure consistency of practices to increase residents’ supports in the housing program. Amy has enhanced external relations which has increased the number of agencies BSL now receives referrals. In addition, she has established a relationship with the San Diego Homeless Court Program to become an Authorized Homeless Court Program Provider.

In her spare time, Amy enjoys spending time with her Belgian Malinoises, hiking and backpacking, traveling, and exploring National Parks.



Housing Director

Nuria joined the BSL team in May 2020 and manages both the Redwood and 4th Ave. houses. She recently graduated from UC San Diego with a bachelor’s degree in Psychology with a specialization in Clinical Psychology. Nuria is grateful for the opportunity to serve women in the San Diego community and strengthen BSL as an organization.

Nuria is a Virginia native who grew up traveling and tries her best to make a trip out of the country at least once a year! When she is home in California she enjoys camping, taking her dogs to the beach, and BBQ-ing with friends.



Program Coordinator

Sami Rogers has been with the Big Sister League since September of 2020 and has been serving as the Program Coordinator since November. Her responsibilities here at the League include community outreach, the coordination of schedules and activities for residents, and overseeing safety guidelines for both residencies. One of Sami’s goals is to provide a secure and comfortable, yet encouraging environment for her residents to learn, grow, and prosper in.

Although this is her first role in the non-profit sector, Sami has always felt compelled to enter the workforce that caters to those who are socioeconomically disadvantaged. She has also first handedly seen the profound impact that transitional living facilities have made in the lives of women who are close to her.

Sami, a native to San Diego county, grew up in the small town of Ramona with big dreams of helping others. Eager to get out and experience the world, she received a BS in Health Science at CSU Long Beach, with an emphasis on community health education. Sami believes that lifelong learning and promoting diversity are essential to tackling disparities.

When she is not dedicating her time to a life of service, Sami can be found listening to live music or soaking up the San Diego sun in whichever way she can!
