portrait of Linda


Linda Monterroso

Linda lives in Las Vegas, NV but was born and raised in the Bronx, NY. She has a brother, Steve with intellectual and developmental disabilities (IDD) who is five years younger. From an early age, Linda was involved in Steve’s care which introduced her to advocacy with AHRC and other nonprofit organizations, committed to finding ways for people with IDD to live full lives. Linda was introduced to the Sibling Leadership Network NY chapter during a conference hosted by ADAPT Community Network (formerly UCP of NY).

In 2018, Linda relocated to Memphis Tennessee where she was appointed by the governor as a member of the Tennessee Governor’s Council on Developmental Disabilities. As a Council member, Linda was among a group of Tennesseans tasked with improving disability policies and practice, educating policymakers and the public through community collaboration. She was also a member of the Tennessee Adult Brothers and Sisters (TABS), a chapter of the Sibling Leadership Network.

Linda relocated to Las Vegas in 2020, where she saw a need to form a Nevada chapter of the Sibling Leadership Network. She partnered with the University of Nevada at Reno to create the Nevada SLN chapter and works with local organizations serving those with disabilities to build the chapter. Linda also serves as a Community Advocacy Committee member for the Nevada Center for Excellence in Disabilities.

When Linda is not advocating for those with disabilities, working as a clinical research director or working on her Doctorate in Health Sciences, you can find her exploring the desert with her husband, rescue dogs and hosting family and friends, especially Steve!

Emma has been involved in the Tennessee Adult Brothers and Sisters (TABS) statewide sibling support network, launched by the Council and Vanderbilt Kennedy Center over a decade ago, since she began working at the Council – she feels lucky to have had the opportunity to attend a few Sibshops as a child and then begin attending the TABS conferences while in college, which inspired her to get involved in supporting fellow siblings. She served as the Council’s representative for Tennessee’s involvement in the national Supporting Families Community of Practice, which explores how families can be better supported throughout the lifespan by state systems and communities.

Emma’s family includes her husband T.J. and their 3 bunnies, her parents, and twin younger brothers (Evan and Brendan) in their early 20s. Her brother Evan has autism, significant communication challenges and lives in his own apartment nearby in Franklin, TN with the help of support staff.

Members At Large

Sibling Support Project Representative

Emily Holl

Emily Holl’s experience with the Sibling Leadership Network began in 2006, when the network was a dream discussed by a handful of siblings sitting in a circle in an otherwise empty hotel conference room.

She also served as Communications Committee Chair of the SLN.

Emily, who has an older brother with intellectual and developmental disabilities, has worked in the disabilities field since 2003. She has experience as a communications professional and as a licensed Social Worker. Emily has conducted research and published on sibling issues, and she had the pleasure of working with Don Meyer and several SLN authors in co-editing “The Sibling Survival Guide.”

Nathan is excited to bring his background from Siblings with a Mission to increase support and connect with more siblings through the Sibling Leadership Network.
