Lydia Callis (she/they)


Lydia Callis is an RID nationally certified American Sign Language Interpreter from 3 generations of Deaf family. American Sign Language is Lydia’s first language because her mother and three younger siblings are all profoundly Deaf. Growing up at a time when there were insufficient laws to accommodate the needs of those who are Deaf, she witnessed the challenges her family members were expected to overcome to access everyday communication. She began interpreting to help her family communicate and to make sure she stayed fluent in the language of her roots.


Lydia founded LC Interpreting Services LLC (now known as SignNexus) in 2014 with the goal of consistently providing high quality, culturally competent sign language interpreters. From decades of experience as an interpreter— first as a very young child, then later in the business world— Lydia knew the diverse needs of the Deaf population were not being met by large multi-language interpreting agencies. She wanted to make it simple for individuals and businesses to ensure they were hiring qualified Sign Language interpreters, while at the same time facilitating deeper, more meaningful relationships with the Deaf, DeafBlind, and Hard of Hearing community.


As a Child of Deaf Adults (CODA) and active interpreter, Lydia endeavors to continuously support the Deaf and interpreting communities in any way possible. She partners with local and national groups to help empower people who are Deaf, and works to educate businesses and organizations about effective inclusion practices for those with hearing loss. American Sign Language is Lydia’s passion and connecting people is her purpose! She is humbled to serve the Deaf community, the hearing community, and the interpreter community through her work with SignNexus.

When she's not working, Lydia enjoys having adventures while spending time with friends. Her personal interests include healthy living, astrology, yoga, and empowering others to commit to their passions in life.
