Our History

Founded in 2018, CLCHC preserves the legacy of Kristina Sergeyeva who passed away unexpectedly at the young age of 24. Mr. Sergey Sergeyev joined forces with Sylvia Caliendo, the wife of Dr. Caliendo who passed away in June 2019 and operated a private practice in Mission Viejo, established in 1994, dedicated to serving the medically under- and uninsured children of Orange County. Mutually, Dr. Caliendo and Ms. Sergeyeva were committed to serving and advocating for the underserved individuals of Orange County.
The catalysts that drove Mr. Sergey Sergeyev’s life purpose to provide high quality and accessible health care was his first-hand experience as a refugee and the sudden death of his beautiful college bound daughter.
CLCHC is the result of the Caliendo and Sergeyev Families’ commitment to their loved one’s passion and commitment to serving the most at-risk and underserved in Orange County.
