Dr. Chuck Dietzen, Founder and President | Indianapolis, IN

Dr. Chuck boasts a diverse career as pediatric physical medicine and rehabilitation specialist, international medicine enthusiast, entrepreneur, professor, and athlete. Growing up in Kokomo, Indiana, over 150 foster children came through his family’s home. His special gift of working with children became apparent to his mother, who encouraged him to become a pediatrician. In 1996 and 1997, he traveled to India on orthopedic missions working alongside Mother Teresa. Inspired to make a deeper commitment to the medically underserved, Dr. Chuck founded Timmy Global Health (formerly the Timmy Foundation) in 1997. His work with Timmy has taken him to Ecuador, Guatemala, Nigeria, Haiti, and the Dominican Republic. He has also traveled to Albania, Cuba, Kenya, Honduras, Bolivia, El Salvador, the Ukraine, and Brazil. He earned his B.S. in Agriculture from Purdue University and his M.D. from Indiana University. He received his training as a pediatric physical medicine and rehabilitation specialist at the University of Alabama Birmingham. He currently serves as the Medical Director for In-Patient Rehabilitation at Riley Hospital for Children at IU Health.

Nancy Wright, Executive Director | Indianapolis, IN

Nancy entered the healthcare field after receiving her Bachelor of Science degree from California Polytechnic University and has dedicated her efforts towards answering the vexing question of how to improve health access for patients and their families. This interest shaped her career choices and led her to spend 20 years with Roche Diagnostics, focused on improving health outcomes for patients with diabetes. With Roche, Nancy had the distinct privilege of working both domestically and abroad in a variety of challenging leadership positions that have prepared her to lead Timmy’s expansion. For five years, Nancy lived and worked throughout the Asia-Pacific region, and it was this period that served as a catalyst for her career change. She believes Timmy has the structure to reverse the cycle of poverty caused by a lack of access to basic healthcare in the communities it serves. She looks forward to using her knowledge of managing large remote teams in multiple countries and developing efficient operating models to continue to grow Timmy Global Health’s work and impact. Nancy is also an avid traveler, yoga enthusiast, and enjoys bicycling and reading.

Alyssa RossodivitaAlyssa Rossodivita, US Programs Manager | Indianapolis, IN

A native of Cleveland, OH, Alyssa returns to the Midwest after a three-year stint in the sunny Rio Grande Valley, along the border between Texas and Mexico. She worked for Migrant Health Promotion, overseeing four state and federal grants that provided health education via the Promotor(a) (community health worker) model. Before that, she worked closely with physicians rural, south Texas to implement a chronic disease self-management program for low-income Hispanic residents. For two years prior to her work in public health, Alyssa was a 7th grade science teacher with Teach for America. It was her students and their health that ultimately convinced her to move back towards her interest in access to healthcare. Alyssa received a B.S. in Biology from Denison University. Like a good liberal arts student, she minored in Spanish and studied abroad in Chile, spent the majority of her time growing and coordinating the service trip program, and played with yeast to complete her senior thesis on DNA repair after UV exposure. She adores making jam and dancing the Texas two-step, and is ecstatic to be back again in the good ole Midwest!

Katherine HornKatherine Horn, Central American & Caribbean Programs Manager | Indianapolis, IN

Katherine joined Timmy Global Health following her senior year at Indiana University, where she graduated with her Bachelors degrees in Biology and Spanish, a certificate in Latin American Studies, and a minor in Chemistry. At Indiana University, Katherine volunteered with the IU Timmy chapter beginning her freshman year, traveling twice to Guatemala to work with Timmy’s international partner organization Pop-Wuj. Katherine’s time with Timmy sparked her interest in global health, Spanish, and living and working in developing countries – all of which led her to study abroad in Chile and Argentina for a year in college. Katherine is an avid traveler, a self-proclaimed adrenaline junkie, and she loves to bake. (Her cookies/brownies/muffins are always up for grabs at the Timmy office!) In the future Katherine hopes to attend medical school or get her Masters in Public Health.

MPC Dominican RepublicLauren Cottingham, South American Programs Manager | Indianapolis, IN

As a Hoosier by birth and Boilermaker by choice, Lauren is extremely excited to join the Timmy team in Indianapolis as a Program Manager, following one year working with Timmy in the Dominican Republic. As an undergraduate nursing student at Purdue, she was first exposed to Timmy when she traveled with the brigade to Quito, Ecuador. Having already traveled abroad to Mexico multiple times for service trips, her time with Timmy created in her a desire to increase her knowledge about public health and underserved populations abroad. During her senior year, she interned at a rural clinic, working on health promotion through education about vaccinations among pediatric populations. She spent time studying abroad in Mexico as an undergraduate student, and just recently returned from Lima, Peru where she volunteered alongside local doctors and nurses to assist with chronic disease prevention in older adult populations through home visits and clinic rotations. She hopes to one day attend graduate school to become a nurse practitioner so that she can continue to work with underserved populations both stateside and abroad.

Muz AhmedMuz Ahmed, TimmyCare Director | Seattle, WA

Growing up, Muz always wanted to pursue medicine. But after his family got their first computer, that dream was derailed. He began to program in high school, and picked up on it quickly. Excelling at this lead him to the University of Waterloo in pursuit of a Bachelors in Software Engineering. Upon completing the 5-year program and mandatory 6 internships with software companies (IDC, Royal Bank of Canada, Google, and Microsoft), he found the perfect role at Microsoft, in Seattle, working as a software engineer on HealthVault and Amalga. That gave him the opportunity to unite his passions, until he caught the travel bug and wanted to get away and experience other places and cultures. After volunteering on a Timmy trip to the Amazon Basin in 2012, he has taken on a full time volunteer position as the developer and director of Timmy’s electronic medical record (EMR) TimmyCare.

Dra. Natalia Garcia, Medical Director | Amazon Basin, Ecuador

Natalia joins the Timmy Team this year as our first Medical Director in the Amazon Basin in Ecuador. She completed medical school in Quito and recently completed her required one year of service in rural medicine in Tena. During this year, she had the opportunity to work with local indigenous communities providing primary care, while simultaneously working on health education projects about preventative medicine. She was connected with Timmy Global Health and the work of the organization through a friend who had heard about Timmy’s primary care clinics. The opportunity to live and work in the Amazon serving the neediest populations and continuing her work in medicine inspired her to join the Timmy Team. She hopes to continue her studies over the course of the next few years by pursuing a graduate degree in trauma and orthopedics. She also plans to continue working with underserved populations in various facets throughout her career.

Eleonore Van Wonterghem, Medical Programs Coordinator | Amazon Basin, Ecuador

After graduating from Edinburgh University with a Major in Medical Biology, Eleonore decided to pursue her strong interests in Public Health and her aspiration to study at the London School of Hygiene and Tropical Medicine, where she completed her MPH. Her passion for traveling and improving people’s health has led her to work for various NGOs worldwide, which made her realize that she wanted to pursue a career in the field of global health. Eleonore became very fond of Latin America after spending a year living and volunteering in Argentina and Chile. She also interned for Alma Sana in Peru, where she worked on a global health vaccination research project funded by the Bill and Melinda Gates Foundation. Most recently, Eleonore has worked with Doctors of the World in London, helping vulnerable migrants access primary healthcare services. This position opened her eyes to the necessity of accessible healthcare for all. Latin America has always left a special footprint in her mind and she is so excited to be back there, leading Timmy’s medical service trips and community health promoter outreach initiatives in the Amazon region of Ecuador.

Ariana Gabaudan, Medical Programs Coordinator | Amazon Basin, Ecuador

Ariana first heard about Timmy Global Health while working in Quito, Ecuador serving indigenous at-risk communities to diminish child labor in major markets. This is where she fell in love with Ecuador, its people and its culture. After taking part in the Chontapunta brigade in March 2015, Ariana joined the Timmy team as Medical Programs Coordinator for the Napo Province in Ecuador. From a Honduran mother and a French-Brazilian father, Ariana was raised in over ten countries around Latin America, Asia and the Pacific due to her father’s work as a humanitarian worker and human rights advocate with the United Nations. Since graduating with a Bachelors degree in Psychology from Concordia University in Montreal, she has worked in the US, Costa Rica, Colombia, and Ecuador with local NGOs focusing on the rights and needs of children in deprived communities. Through her work, she has developed a passion for public health and community development, which she is thrilled to now share with Timmy and the communities it serves. Ariana is fluent in Spanish, English and French, and enjoys scuba diving as a certified dive master. In the future, she hopes to pursue a Masters degree in Public Health and continue to learn and be inspired by different cultures around the world.

Alexandra Yost, Medical Programs Coordinator | Quito, Ecuador

Alexandra is thrilled to return to Ecuador as Medical Programs Coordinator in Quito. As a Peace Corps volunteer, she lived in Ecuador, serving in a maternity hospital to provide care to pregnant adolescents and persons living with HIV. Prior to joining the Timmy team, Alexandra worked with various non-profits, most recently as a victim advocate to survivors of sexual assault and as an educator on preventing sexual violence. Her passion for grassroots non-profits began with her work in a residential drug and alcohol rehabilitation community and her collaboration with mentally ill inmates. A proud Utahan and a graduate of the University of Utah with degrees in Psychology and Art History, Alexandra enjoys wilderness treks and is an avid consumer of autobiographies and NPR. She is honored to be a part of Timmy’s mission to promote global health and accessible healthcare in underserved communities in the beautiful country of Ecuador.

Alejandra Fernandez, Medical Programs Coordinator | Santo Domingo, Ecuador

Alejandra is one of the newest members of the Timmy Team, and joins the staff as the first full-time Medical Programs Coordinator in Santo Domingo, Ecuador. Alejandra’s love of people and cultures stems from her studies in Anthropology. As a child, she traveled with her family and eventually by herself and reveled in seeing new places and meeting new people with different languages, traditions, and ways of life. This brought Ale to teach English for a year in Nanchang, Jiangxi, China. She was first exposed to Timmy during that year through a family friend. The opportunity to live and work in a different country as well as continue her passion for Anthropology through work with the Tsachila people led her over 10,000 miles to Santo Domingo de los Tsachilas, Ecuador. She hopes to help facilitate a connection between the different cultures of Ecuador and the United States to better promote global health. In the future, Ale hopes to further her studies with a Graduate program in Paleopathology.
