Alaleh was born and raised in Iran and moved to the US at the age of 17 to pursue higher education. She graduated from the University of California, Irvine, with a Bachelor of Science in Biological Sciences, and then from the University of California, San Francisco School of Dentistry. After graduation, she practiced dentistry throughout rural Texas with a focus on pediatric dentistry.

After returning to the Bay Area, she continued caring for children in under-served areas in federally qualified community health centers. In 2010 and 2011, as part of Medical Missions for Children, Alaleh raised funds to open a dental clinic in Gitwe, a small village in Rwanda that previously had no access to dental care. She traveled two consecutive years to Gitwe to help to train the local dentist to treat patients. Locally, Alaleh devoted countless volunteer hours to treat kids in the Samarithan Free Dental Clinics in San Mateo and Redwood City. For the past 5 years, Alaleh worked at the Silva-Tiburcio Vasquez Health Center Pediatric Dental Clinic in Hayward, CA, treating mostly children from Central America and Afghanistan.
