Celebrating Life Community Health Center

Demonstrating Christ’s love, compassion and generosity to all underserved communities of Orange County, by providing accessibility to holistic, high-quality healthcare and social services, all at a reasonable cost.

Founded in 2018, Celebrating Life Community Health Center (CLCHC) honors the legacy of Kristina Sergeyeva, who tragically passed away at the age of 24. Her father, Sergey Sergeyev, was inspired to create a healthcare organization dedicated to serving vulnerable communities after experiencing firsthand the challenges of being a refugee and enduring the sudden loss of his daughter.

In this mission, Mr. Sergeyev partnered with Sylvia Caliendo, the wife of Dr. Caliendo, who passed away in June 2019. Dr. Caliendo had operated a private practice in Mission Viejo since 1994, dedicated to providing care for medically underserved and uninsured children in Orange County. Both Kristina Sergeyeva and Dr. Caliendo shared a deep commitment to advocating for those most in need.

CLCHC is the realization of the Sergeyev and Caliendo families’ shared dedication to continuing their loved ones’ passion for accessible, high-quality healthcare for Orange County’s most at-risk and underserved populations.

Since 2018, Celebrating Life Community Health Center has been committed to providing the highest quality care to those we serve. Through community outreach and a comprehensive range of services, we strive to uplift and empower every individual who walks through our doors—fostering a community where health and dignity are accessible to all.

Did You Know?

Heart disease is the leading cause of death.
Suicide is the second-leading cause of death among youth ages 14 to 25.
Fentanyl-related deaths surged by 321% between 2016 and 2022.
These alarming trends highlight the urgent need for accessible, high-quality healthcare. At CLCHC, we are committed to addressing these challenges through specialized programs in behavioral health, heart screenings, and pediatric, youth, and college care.

Additionally, neonatal care, obesity, cancer, cardiovascular disease, diabetes, and respiratory disorders remain major health concerns across Orange County. The rise in these conditions is a symptom of a larger issue: lack of access to comprehensive healthcare and support.

We are dedicated to bridging this gap and ensuring that every individual receives the care they need to lead a healthier life.

Dear Community Partners,

Join us in transforming healthcare. At Celebrating Life Community Health Center (CLCHC), we are dedicated to delivering high-quality medical care and social services to Orange County’s most vulnerable populations. As a family practice with specialized programs in heart screening and behavioral health, we believe healthcare is more than a service—it is a sacred mission.

"Healthcare is a sacred mission. It is a moral and scientific enterprise. Doctors and nurses are stewards of something precious." — Avedis Donabedian

As a steward of this mission, I am honored to serve communities in need, and I firmly believe we can transform the healthcare system—reducing costs, improving quality, and expanding access. Our long-term vision is to expand into the most underserved and neglected areas, ensuring that no one is left behind.

In the short term, we are focused on strengthening our newly acquired clinics in Costa Mesa, Santa Ana, and Irvine. These facilities require urgent improvements, both in infrastructure and staffing. We need more specialists in mental health, pediatrics, and neonatal care to address the growing healthcare needs in our community.

Recent data highlights critical gaps in student mental health and heart disease treatment—gaps that lead to preventable disabilities and deaths. Addressing these issues requires proactive, preventative, and actionable solutions.

We invite you to join us in this vision. Together, we can close these treatment gaps and elevate the standard of healthcare in the communities we serve. With your support, we can make a lasting impact on the health and well-being of those who need it most.

Sincerely,
Sergey Sergeyev
