Dr Krishna Rajani

UCSF – Fresno Clinical Professor, Neonatologist

Born to Indian immigrant shopkeepers in East Africa, I was raised in Blantyre, Malawi before being sent to boarding school in present day Zimbabwe. Under the direction of a group of catholic priests known as the Marist Brothers, I became interested in science and pursued my undergraduate studies in London. I quickly grew interested in medicine, and was fortunate to matriculate from the University College Hospital London (University of London, England) from where I rotated through Northwick Park Hospital, well known for its endeavors in medical research. My love affair with pediatrics took hold early, and I continued my training at The Hospital for Sick Children at Great Ormond Street (GOS), the inspiration behind the creation of the Children’s Hospital of Philadelphia (CHOP). As a result of their long-standing relationship, I was invited to spend one year as an exchange resident at CHOP. With my wife and a few belongings,I arrived in the “City of Brotherly Love” on July 4, 1976 – the 200th anniversary of this country’s birth! After a fulfilling experience at CHOP and in America, I decided to remain in the United States and pursue my fellowship in Neonatology at UC Davis.

One year and 180 miles later, I arrived in Fresno to begin practicing neonatology in 1978. Since then, I have taken an active role in resident teaching through the UCSF Fresno medical program, where I am an associate professor of Pediatrics. I regularly deliver lectures to the residents and find the enrichment of our future pediatricians to be most fulfilling.

Clinically, I spend my time at both Community Regional Medical Center (CRMC) and Clovis Community Medical Center (CCMC).  CRMC is the only facility that transports and accepts high-risk mothers in Central California. As a result, there is a very active perinatal program with five perinatologists and over 11,000 deliveries per year between the two hospitals. The result is a very diverse, interesting patient population with many challenging cases.

Since my arrival in Fresno over 30 years ago, I have taken on a number of leadership roles in the medical community. I have served as Chief of Staff, a member of the Board of Trustees, Chief Medical Officer and member of the board of the foundation of Valley Children’s Hospital and a board member of California Association of Neonatologists (CAN). Until recently I was the medical Director of CRMC 84 bed NICU. I have been a member of AAP for 30 years and am an active member of the Fresno-Madera Medical Society. As community service, I have given my time to a number of local organizations including the Board of March of Dimes. I am a currently a member of the California Association of Neonatologists (CAN). I serve on the Board of Central California Blood Bank and am the treasurer of the Hindu Temple of Fresno. I am the Past President of the Allied Medical Outreach and Relief (AMOR). AMOR is a community benefit organization that works strategically with local partners to build healthier communities in areas of concentrated poverty. Whether it is across the globe or in our own backyard, AMOR increase access to quality, affordable health care and health education. AMOR tailors their approach to the unique culture of the people AMOR is serving.
