Daniel D Mast '77, DO, FACP

Dan Mast lives in Willow Street, PA and is a practicing physician of Internal Medicine at Union Community Care in Lancaster, PA, with added qualifications in Geriatric Medicine. 

After serving with Indian Health Service and as an internist and early hospitalist with CIGNA in Arizona in the 90’s, he then returned to PA and private IM/Geriatric practice. His practice provided hospital, office, long-term care, and wound care. He served as medical director for three wound centers  combined with clinical teaching of students/residents/fellows. He has served as a board officer for both an elder care consortium as well as its long-term care facility (Landis Communities/Homes). His passion is for serving and caring for a diverse range of elders, balanced with mentoring and teaching our next generation to be competent and compassionate medical caregivers.

Dan and his late wife, Cindy, are parents to four adult children who are all alumni of LM. Dan especially enjoys the time he gets to spend with his five grandchildren. He is a part of the James Street Mennonite Church community. We’re so thankful for his involvement at LM as a faithful and generous donor, and to Cindy, who was a longtime board member at Lancaster Mennonite School. In the spring of 2022, Dan donated a Southern Magnolia to LM, which the Mast family gathered to plant in honor of Cindy’s caring  legacy.

Jennie Weaver Groff ‘95 & Jonathan Groff ‘93

In 2010, Jennie and Jonathan joined ownership of Stroopie, Inc., a social enterprise that exists to provide meaningful employment for resettled refugee women while making delicious Stroopies (stroopwafel cookies). In 2016, they opened the Sweet Shoppe in downtown Lancaster, PA where they offer the unique combination of their family's Groff's Candies, local ice cream, and freshly made Stroopies. 

Their employees, women resettled in Lancaster from Syria, Sudan, Congo, Nepal, Burma, and Eritrea make approximately 15,000 Stroopies a week that are sold in Lancaster and all across the U.S. During the paid work day, they also have an ESL class that helps prepare the women to grow up into management at Stroopies, or to launch into other careers. Jennie and Jonathan are leveraging the private sector to create a beautiful business that allows them to live out their call from Jesus to love their neighbors and create a safe work environment for the women to know their value and to have renewed hope as they start their lives in a new place. 

They have four children and live in Lancaster City where they participate in a home church. Jennie and their employees often visit LM to speak in chapel to share the exciting story of their social enterprise, the impact it is having on the women, and the way God is working in positive ways.
