Andrea Naff

Andrea graduated from Texas Christian University with a degree in speech-language pathology then with her masters from Radford University in Virginia. After just a handful of years practicing as a medical speech pathologist, the Lord called her to raise her rapidly growing family while homeschooling them for over a decade. Toward the end of that season, the Lord gave both Andrea, and her husband, Jason, an overwhelming burden to surrender to the call to vocational ministry (Jason) and the vision behind Hope Clinic (Andrea). It is her desire to walk alongside the Family of Hope Clinic as well as the City of McKinney to serve, strengthen and honor all people for the Common Good of the Kingdom of God. Andrea and her husband live in McKinney and have the honor of raising their six daughters.

Jenny began as a volunteer with Hope Clinic on day one and was invited to join the staff as Patient Care Coordinator in February 2019. She studied Spanish and Music at Ouachita Baptist University and has served as the Student Ministry Coordinator for the Parks Church. There is no better place to combine her passion for serving others, sharing the love of Jesus, and employing her Spanish language skills than serving the patients of Hope Clinic. Her greatest joy has been experiencing Jesus in each patient that walks through the door.

Over the course of her career, Vicki has considered herself blessed to work in both the nonprofit and corporate worlds, honing her skills in marketing, events, writing and fundraising.

Operating alongside a diverse employee culture, she witnessed firsthand the struggle low income individuals without health insurance undergo.

Caitlin Twyman

Founder


Caitlin graduated from Oral Roberts University with a degree in Pastoral Care. After a year serving with missionaries in the red light districts of Belgium, she was inspired to attend the University of Tulsa School of Law, with plans to use her degree to serve those without a voice. In law school, she fell in love with immigration law and the immigrant community and began practicing as an immigration attorney. It was in this world that she began to discover the difficulties faced by the uninsured. It is her desire that every Hope Clinic patient not only receives the highest level of care, but feels welcomed, respected, and loved—for we love because He first loved us. Caitlin and her husband, Steve, live in McKinney and have a daughter, Audie, here on earth and a son, Benson that lives in heaven.

Our Board

Kyle Redel

The Parks Church


At Hope Clinic all people are treated with dignity, care, and respect as image bearers of our God. Hope Clinic tangibly demonstrates the love of Jesus to the uninsured in McKinney. I believe in the mission of Hope because at the heart of it is the mission of Christ.

Stephen Twyman, MD, MPH

John Peter Smith Hospital


“We have a lot of need in our community, and Hope Clinic is an opportunity to meet that need. It’s been rewarding and fun to get to engage with our community, to try to partner and work together to meet the health and spiritual needs of our neighbors. For medical professionals who are looking to remember their original goal of helping people and making a difference, Hope Clinic is a perfect opportunity. It is an outlet for one-on-one patient relationships that we providers sometimes don’t get as much as we want.

Hope Clinic is unique. Our patients feel at home. We’ve had multiple patients come up to the clinic just to hang out with us and I have never heard of that in another clinical context. That is the best thing that we have going for us– God has graciously empowered us to really connect well with our patients and to establish a place where they feel comfortable, welcomed and loved. If you are someone who knows that you would like to use your medical skills in some way to advance the kingdom of God, then you will absolutely have opportunities to do that here. If you are not a believer, but you know that there is more to what you do and the skills that you have than just making money, Hope Clinic is definitely a place for you.”

Pat Reilly, CPA

Reilly CPA Firm


“Hope Clinic of McKinney provides a unique service to those who could not otherwise receive medical help. The pastoral care provided is a special opportunity to speak the Gospel to those we might have never met. Though I have zero medical expertise, I can help provide needed medical services through my volunteered talents. ”

Billy Booker

Retired Psychological Consultant


“I agreed to start volunteering in a Pastoral Care role at Hope Clinic because I saw the great works they were doing in Collin County and I wanted to be a part of that effort. Additionally, serving on the Board has given me an opportunity to further impact the services Hope Clinic provides to the community.”

Teresa Craighead

New Generation Media


“From the moment I became aware of Hope Clinic’s mission to reach uninsured patients in McKinney and provide them with a sound medical home, I became a fervent supporter. The staff at Hope is caring, dedicated, and talented. The Clinic’s mission to treat the whole patient, including their soul and spirit, embodies Jesus’ message to care for the needy. Serving on the board is a privilege, and gives me the opportunity to further support Hope’s mission and future.”

Sam Deford

The Parks Church


Several encounters with those who had little or no access to healthcare led to a deep desire to see Hope Clinic succeed. I fully believe in the mission of Hope to serve the individuals and families of this city by meeting medical needs while engaging the soul of each patient. As a board member, I am very thankful and honored for the opportunity to serve the patients and providers at our clinic. My hope is that our community continues to become more aware of those around us that need care and encouragement.

We are all in this together!
