Manju Sachdev M.D.

Manju Sachdev, M.D.

Clinical Assistant Professor, Department of Primary Care & Rural Medicine, Texas A&M School of Medicine

Dr. Manju Sachdev is a Board Certified Pediatrician who was born and raised in Newfoundland, Canada. She began her career in Victoria, Texas as a private practitioner. Her aspiration to learn more about the administrative aspects of medicine led her to join Driscoll Children’s Hospital Quick Care Clinic Victoria as their Medical Director, while continuing to balance a private practice. After being approached about developing the pediatric facet of Detar Hospital’s Family Medicine Residency program, Dr. Sachdev immediately took a proactive role by volunteering to teach the residents about common pediatric illnesses. She subsequently transitioned into joining as a faculty member; her enduring enthusiasm has since led to the tremendous growth and development of the program’s pediatric component, thus etching the realm of pediatrics as a key and integral part of the curriculum.

In addition to her dedication to medicine, Dr. Sachdev has a vast array of interests which she has incorporated into her existence as a wife, mother and a physician. One of her most telling moments was as a participant in the 2004 Mrs. Texas-America Pageant when she was asked by one of the judges how a woman of her ethnicity could fit into the traditional norm to become a pageant title holder in the state of Texas. She creatively replied, “The fundamental beauty of Texas lies in its acceptance and diversity, and that is what has brought me this far.” That statement earned her a ‘top ten’ title, making her one of the first Indo-American women to place in a state-wide national pageant. This renewed sense of self-confidence instilled a yearning to pursue her other interests, including a passion for public speaking, thus lending a national television health series to her name as host, writer and producer.

Indian Classical and Bollywood-style dancing has been engrained “in her blood” from a very young age, and to showcase that, she choreographed and performed in an unprecedented medical parody video in 2019 titled One Sikh with the celebrity physician ZDoggMD alongside the Detar Family Medicine residents.

Dr. Sachdev is a strong proponent of the beliefs of Mahatma Gandhi who beautifully stated that, “The best way to find yourself is to lose yourself in the service of others.” This attitude is reflected in her multitude of philanthropic projects, including helping to raise funds for the victims of Hurricane Harvey, being a strong supporter of the American Veteran’s Association, and supporting numerous animal rights and rescue groups.
