Below is an overview of the medical specialties that play a vital role in our care teams, for which we’re recruiting new volunteers. Credentialing requirements for each role are included with the descriptions.
Anesthesia Providers
Anesthesiologists, Pediatric Anesthesiologists, Nurse Anesthetists and Anesthesia Clinical Officers
Anesthesia professionals are essential to every surgical program, ensuring children and adults receive safe, effective anesthesia and pain management across a wide range of ages and clinical environments. They work in close partnership with surgeons and nurses to maintain patient safety and comfort throughout each procedure.

Surgeons
Plastic Surgeons, Cleft Surgeons, Oral & Maxillofacial Surgeons
Surgical specialists perform life-changing cleft procedures and often support comprehensive treatment planning. They collaborate with multidisciplinary teams to deliver surgery safely and efficiently in hospitals, clinics and community settings around the world.

Nursing Team
Operating Room Nurses, Recovery Room/PACU Nurses, Ward Nurses
Nurses provide critical support before, during and after surgery — maintaining sterile environments, monitoring patients closely and ensuring safe recovery. Their adaptability and clinical expertise make them indispensable in fast-paced, resource-limited surgical settings.

Pediatric Specialists
Pediatricians, Pediatric Intensivists
These providers assess overall patient health, manage complex pediatric needs and support children throughout the surgical program. Their insight helps ensure patients are ready for anesthesia and surgery.

Cleft Care & Rehabilitation
Speech-Language Pathologists, Nutritionists, Psychosocial Care Providers
Not all cleft care is surgical. Specialists in these areas offer essential non-surgical support — helping children develop feeding, speech, emotional resilience and long-term wellbeing. These roles contribute to comprehensive, patient-centered care models across various program types.

Stories of Impact
Discover what our volunteers have to say about their experiences with Operation Smile.
Dr. Vivek Panchapakesan, Volunteer Cleft SurgeonWith the treatment provided by Operation Smile, in places where life itself is so challenging, these children are given a chance. An opportunity to eat and drink normally, the ability to speak naturally, and to simply look – and smile – like everyone else. I became a plastic surgeon because I saw how surgery could transform a child’s face. When I began volunteering I saw how the transformation is more than just physical; Operation Smile transforms lives.
Karina Olivo, Volunteer Clinical CoordinatorI believe that the work Operation Smile does, changes the world we live in. There is a big lack of safe surgical services across the world and most of the burden is in developing nations. By joining Operation Smile, I have had the opportunity to use my skills and knowledge to be part of an amazing group made up of thousands of volunteers who share the common desire to change the lives of those most in need and bring back the smiles of children, families and entire communities. My hope is to continue to be able to bridge the gap of inequality in the world and be able to continue to change the world one smile at a time!
