About Us

Himalayan Health Exchange, Inc.

Himalayan Health Exchange Inc. was established to provide a cross cultural learning nd community service based adventure.

In 1996, founder Ravi Singh, a native of Himachal Pradesh now living in the U.S., organized a medical camp for a US based organization in the Indian Himalayas. This experience encouraged him to make future expeditions, under Himalayan Health Exchange, to be community service based adventures. Himalayan Health Exchange’s expeditions now cover 4 remote regions of the Indian Himalayas and, through trekking, hiking and road-travel, our teams get a rare opportunity to learn from lifestyles of the natives and in return teach them the importance of good health and well being. Varying levels of trekking, hiking and road travel provide a unique and profound intercultural experience to individuals of all ages who may be interested in doing a international health rotation or a independent field study project. Himalayan Health Exchange Inc. was established to provide a cross cultural learning and community service based adventure.

The focus of our expeditions is to provide a quality educational experience mixed with adventure and culture and to improve local well being. Primary and public health is integrated into all of our expeditions. A health awareness campaign includes general and oral hygiene, diet and nutrition, reproductive health and prevention from commonly found infectious diseases in the Trans-Himalayan regions along the Indo-Tibetan borderlands. Patient population includes natives, Tibetan settlers and children living in monastic schools, orphanages and Buddhist nunneries.

Each expedition is designed and planned around local weather, road and trekking conditions with safety of participants being the top priority. Ample time is included for exploring the surrounding region. A typical camp day comprises four to six hours of field work. Depending on the group’s wishes, we may tour, hike or visit a village or settlement for the remainder of the day. We return for evening case study presentation session and a relaxing evening to enjoy a meal and conversation before retiring for the night.

Meet our physicians and supervisors who have contributed their time and talent to provide care to our patients, and supervision to students and residents.  Their support and guidance has helped HHE build 5 permanent clinics that provide year round care to patients living in some of the most remote regions of the Western Himalayas.

In 2002, she and a friend worked in the high Andes of Peru for 2 weeks as part of a child survival project and they returned again in 2003. Since then she has also traveled to Ecuador several times, the Dominican Republic several times, helped start an IH track for interested residents and students at her local teaching hospital, co-chaired an IH state committee of the AAP and had her first trip with Himalayan Health Exchange in June 2010.
