To increase access to healthcare to less fortunate communities in Ghana by bringing doctors and healthcare personnel to those communities. OHCMC will do this by supporting the existing structures or creating new ones that will help these communities meet their healthcare needs.


Our Motivation

Olive Health Community Mobile Clinic (OHCMC) is an incorporated not-for-profit organization in the States of Minnesota and Wisconsin. The organization is founded by John- Jeremiah Kretchy MD, FACP a physician working in the state of Wisconsin, and his wife Mrs. Adelaide Kretchy.

Dr. Kretchy is a Ghanaian native who truly believes that everybody should have access to basic medical care. In 2015, after traveling to his native country Ghana, and saw the untenable situation against diseases that villagers face in Ghana, he decided to launch an organization that will provide free basic healthcare to his compatriots in his native country Ghana.

OHCMC with its mobile clinics will carry out its mission by providing free healthcare to the villagers and also promote health and hygiene through educational seminars and training. According to World Health Organization (WHO), healthcare is very variable throughout Ghana. Urban centers are well served, and contain most hospitals, clinics, and pharmacies in the country whilst, rural areas often have no modern health care systems.  Patients in these areas either rely on traditional African medicine, or travel great distances for health care. In 2015, Ghana spent 6.2% of GDP on health care, or US$30 per capita. Of that, approximately 34% was government expenditure. Life expectancy is 63.76 years with males and 68.66 years for females. There were about 15 physicians and 93 nurses per 100,000 persons in 2010.

  • Dr. Kretchy is the Founder and President of Olive Health Community Mobile Clinic. He earned his medical degree from Kwame Nkrumah University of Science and Technology in Kumasi Ghana.  He then completed his residency at Columbia University Medical Center in New York.  He is board certified in both Internal Medicine and Bariatric Medicine by the American Board of Internal Medicine and Bariatric Medicine respectively.  Currently he works at Thedacare as an Internal Medicine Hospitalist, he is also an Assistant Clinical Professor of Medicine at the Medical College of Wisconsin.  Dr. Kretchy believes in providing compassionate patient-centered care.  When he is not working, Dr. Kretchy enjoys spending time with his wife Adelaide and family.

  • Sara lives in Green Bay, WI where she graduated with a BSN from Bellin College of Nursing in 2017. "I knew I wanted to be a pediatric nurse when I went on my first mission trip to Belize in high school. I knew that I wanted to care for children and families at a more global level, while also being able to help my own community. I went on multiple mission trips, but most recently I was able to spend some time in Accra, Ghana. I absolutely fell in love with the culture and knew that the Lord was pulling on my heart to do more work there. I was an RN on a medical floor at ThedaCare for 1.5 years (where I still work part time), and I now am a full time Pediatric Nurse at St. Vincent’s Children’s Hospital. Every day I am touched by the lives of the families I care for, and I can’t wait to show my love for the people in Ghana. My life verse that has been my rock wherever I travel is Joshua 1:9
