International Health Partners seeks to improve health care for the people of Tanzania by integrating medical knowledge, techniques, and best practices within the East African culture. We employ and train local health care professionals and rely on the generosity of others to build resource efficient facilities without sacrificing the care for our patients.


Our organization has solely focused on improving healthcare in Tanzania for the past 21 years and currently helps to support the St. John's University School of Nursing in Dodoma. Recently we embarked on a new endeavor at Zuzu to build a full service hospital in an underserved area. This hospital will eventually serve as a training facility for professional development across East Africa. 


IHP's model seeks to develop well-run facilities and provide the best care, at a nominal cost to the patients within the communities we serve. We welcome volunteers from all over the world who generously give their time to work with local people and make a meaningful difference in the world. We, and the people of Tanzania, appreciate your support.


Dr. Bon Mazezele with two happy patients.



Meet Our U.S. Board Members

Charles Powell, M.D



Dr. Powell began his career in medicine in 1993, attending medical school after a successful career as a symphony orchestra musician of nearly 20 years. While in training, he was immediately drawn to neonatal care and neonatal intensive care. After working as a community pediatrician several years, Dr. Powell began working and training in a high level neonatal intensive care unit near his home in the Kansas City area. Dr. Powell has now been working almost exclusively in neonatal care for more than 15 years.

The relationship with International Health Partners began in 2009 with a trip to the Nyakato Health Center and continued at Zinga; the previous projects IHP-US supported in Tanzania. Charles has been an active participant in planning and directing several projects. While Dr. Powell continues to work in the United States, he and his wife (also a practicing pediatrician) plan to spend considerable time volunteering at Zuzu in teaching and assisting with the operation of the hospital, as soon as the principal units are operational.  Dr. Powell serves as President of International Health Partners - US and International Health Partners TZ.

Marie Quanbeck, MSE 



I grew up in Norway and at Marangu, Tanzania, where my parents were Norwegian missionaries. I was eleven when we arrived in Tanzania, ready for adventure. I loved Marangu on the slopes of Kilimanjaro: the people, the countryside, the beauty of Kibo, the view of the plains far below and the distant Pare Mountains, the woods and river with its rapids and waterfalls to explore.

The hard part about being an MK (Missionary Kid) is going away to boarding school. But lucky for me, there was Augustana School at Kiomboi in Central Tanzania, where some 70 kids grades 1–8 became family and forged friendships that are still strong decades later. The school physician? Dr. Denny Lofstrom.


I got my BA  from Luther College, Decorah, IA, with an English major and a minor in secondary education, and my 

MSE from Drake University, Des Moines, IA. I worked as a commercial artist and newsletter editor for Newton Manufacturing, a specialty advertising firm, and later I taught in the Newton Community Schools from 1987–1997. Then I worked as a technical writer with Wellmark Blue Cross and Blue Shield in Des Moines from 1998 until my retirement in 2014.

When the call came to support the work of the Lofstroms and IHP, I felt privileged to do my part to give something back to the country that gave me such a happy, secure childhood. My husband Duane and I went on a church mission trip to work with Paula and Denny in 2008. It was truly a homecoming for me. Tanzania will always own a big piece of my heart.

Joyce Zemel


My name is Joyce Zemel and I have been a friend of Paula since we started kindergarten together back in what people call mid-century. I became a part of the IHP Family and member of the board 10 years ago.  Paula invited me after we had reconnected at one of our many high school reunions. My work background for the 40 years I was on payroll was mostly involved as a customer service representative in the financial industry.  I am a mother of three, grandmother of three, and I’m now awaiting my first great-grandchild. 


I have tackled the job of being the keeper of the bank account transactions as a board member and treasurer for these past 10 years.  I am now going to pass the baton to a younger more energetic and most likely more qualified enthusiastic and gracious young man. I will continue as a board member and be helpful in any way I can going forward.

Mary Pace, M. Ed.


My name is Mary Pace and I live in Independence, Missouri. This has been my home for my whole life. I started my work career at Kansas City Life Insurance leaving there in 1995 as a Medical Claims Examiner. At that time, I decided it was time to experience college. I graduated in 1999 with a Bachelor of Science in Elementary Education and Early Childhood. I taught elementary for 6 years in Lexington and 5 years in Grain Valley, Missouri. At the end of 2010, I decided it was time to make a change and became certified in Special Education for Mild to Moderate Disabilities. I currently work at Maple Valley School for the Severely Disabled and have a Master's degree in Education. 


My first time traveling Tanzania was to Nyakato in 2009 along with David West and a group of 18 people from the church where we both attended. I became hooked the minute I got off the plane and have gone back every year possible since that day. I have volunteered at Nyakato for 5 years and Zinga 6 years. In the beginning, I helped Paula take care of everyday things, computer work and construction. Three years ago we found that because of my professional experience, I was allowed to perform therapies for the children in Zinga. I provide physical, occupational and language therapy in the clinic. I was just elected to the board in October 2019,

David West

David has been a board member since April of 2011. He first spent time in Tanzania from 2004 to 2006 on the Iramba Plateau learning basic Swahili assisting Mary Kitundu and the Lofstroms at Iambi Hospital by overseeing the construction team of 20 Tanzanian nationals, not realizing at the time how his life was forever changed for the better by the experience. He continued to stay involved upon his return to the U.S., assisting as he was able, and has been able to return six times so far. He spent most of the past decade doing social work, managing employment services programs for people with disabilities, and still holds a national certification as an employment supports professional. In 2018 he was awarded a Foreign Languages and Area Studies Fellowship attending the African Flagship Languages Initiative program at the University of Florida where he received a certificate for Intermediate Swahili.

David was fortunate enough to spend a year over 2018-2019 in Tanzania again. As well as helping at the Children's Hospital in Zinga, he also attended the University of Dar es Salaam learning more advanced Swahili, tutored students with their English, attended classes on good governance and sustainable development, and played keyboard, percussion, and drums in the University Fusion Band. He received his degree in Interdisciplinary Studies from the University of Missouri and is currently working for the benefit of IHP.
