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 native language because her mother and three younger siblings are all profoundly Deaf. Growing up before there was adequate legal framework to protect the rights of the Deaf population, she witnessed the challenges her loved ones overcame every day just to access basic communication. She began interpreting to help her family communicate and to make sure she stayed fluent in the language of her roots.


LC Interpreting Services LLC (now known as SignNexus) was founded 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.


Lydia supports local and national groups to help empower people who are Deaf in their lives and careers, and works to educate businesses and organizations about inclusion practices for Deaf/DB/HoH professionals. She completed the DeafBlind Interpreting National Training and Resource Center DBII Cohort training program for tactile and protactile interpreting to better understand, honor, and effectively meet the distinct communication needs of those who are DeafBlind. As a Child of Deaf Adults (CODA) and being engaged to DeafBlind woman, Lydia is humbled to serve the expansive Deaf community, the interpreter community, and the hearing community through her work with SignNexus. 


When she's not working, Lydia enjoys having adventures while spending time with friends. She is passionate about astrological and spiritual interpreting and exploring new ways to increase Deaf access to the metaphysical fields of study. Her personal interests include healthy living, yoga, and empowering others to commit to their life purpose.
