Donate to the Cookes

Chris and Sarah Cooke, along with their four daughters Riley, McKenna, Amelia, and Lucy, arrived on May 26th, 2015.

Chris is a registered nurse and will fill an important role in overseeing the medical aspect of our ministry.  Because of his background in trauma nursing, we will be able to offer training to the local nurses who fly along with us on emergency flights, as well as more advanced care for patients in life-threatening situations. We’re looking forward to the avenues this will open for further ministry in the local clinics, hospital and among the medical community. Chris and Sarah will both be a part of our hospital ministry as well!

The Cooke family shared that they are eager to begin this journey with Samaritan Aviation. As an RN, Chris is thrilled to be a part of sharing Christ’s love and saving lives through medicine.

Hospital Ministry Assistant

Robert Mapmangu

We first met Robert in 2015 while he was working as a contractor on our compound renovation. We were initially drawn to Robert because of his dependability, hard working nature, and great sense of humor. As one project finished and the next started we requested that he be on the crew of workers. During this time period we began a daily Bible study with the construction workers. Each day as we taught, it became more and more apparent that Robert was a believer who knew and loved the Word of God. After several more months continuing to disciple him and getting to know him and his family, Robert joined our national staff and is thriving in his training to become a leader in this important ministry.
Robert and his wife, Ludi, have been married for 11 years and have three children: Rodney (10), Guesti (9), and Maino (1). He brings with him 8 years of experience as a welder and carpenter, which is a huge asset as he also helps maintain our compound. While typically quite and reserved, Robert becomes passionately bold when sharing the gospel of Christ and caring for our patients in the hospital. He has been an excellent addition to our staff and we are excited to see him grow and develop as he serves in our hospital ministry.

Bryan Yeager

Bryan says, “I have been a fan of Samaritan Aviation since 2000. At the time I was introduced to this organization I was the senior pastor of a church in Montrose, Colorado. Over the years our congregation as well as my family supported and partnered with several projects Samaritan had taken on. It was also our churches pleasure to have had Samaritan Aviation’s President Mark Palm, on our staff for three years as one of our worship pastors. Mark and I have many fond memories working together. It is with this long term relationship with Mark and several of the board members as well as a strong belief in what Samaritan is about that I have accepted my new role with this organization. I look forward to being a part of the team as we move forward with the mission of bringing hope and a message to the people of Papua New Guinea.”

Bryan and his wife Mary have been involved in ministry since the late ‘70’s. They received their missionary experience when they went to Nairobi, Kenya in 1987 and began doing missions work in one of the largest slums in East Africa.  Bryan has traveled in over thirty countries speaking in leadership conferences in many of them.  In 1993 Bryan went on board with Promise Keepers and while he was with this organization he served as the National Director of Volunteers as well as the National Director of Events.  In 1998 Bryan and his family accepted the Senior Pastor role of Grace Community in Montrose, Colorado. Samaritan feels blessed to have a person of Bryan’s experience, qualifications, passion, and expertise joining our team.

Paul Forehand

Paul Forehand is a professional pilot, flight instructor, and former flight school owner. While visiting the Experimental Aircraft Associations AirVenture in Oshkosh, WI in July of 2015, Paul noticed an article written about Samaritan Aviation in the daily newspaper. He was prompted to make the trip over to the seaplane base to learn more about their mission and see their second airplane. After talking with Mark Palm about the services SA was providing, it became clear to Paul that a second plane was critical for the operation to be most effective. Paul returned to his church in North Carolina and shared what he had learned with two mens groups. Both agreed to help support SA with monthly donations. In February of 2016, Pauls church was starting a focus on missions, local and world-wide. Bryan Yeager was invited to come and speak. As a result, the church as a whole supports SA.

“Providing life saving services opens the door for the real work of sharing Gods love with the people of PNG”.

Paul and his wife of 30 years, Diana, live in Garner, NC. They have three grown children and four grandchildren.
