Meet Our Team

Caitlin Twyman

Executive Director

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.

Heidi Willers

Operation Manager

Heidi was a member of Hope Clinic’s planning committee and volunteered as the Credentialing Coordinator before joining Hope Clinic’s staff as the Operations Manager in late September 2017. Heidi enjoys working with a terrific team of staff and volunteers committed to providing a medical home that delivers high quality health care to the medically underserved of McKinney and seeing the difference Hope Clinic makes in our patients’ lives. Before joining the Hope Clinic staff, she practiced commercial litigation in Dallas and guardianship and probate law in Collin County. She is a 2013 graduate of SMU Dedman School of Law. Heidi lives in Collin County with her husband and two daughters.

Jenny Konvicka

Patient Care Coordinator

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.

Denise McMillan

Volunteer Coordinator

Being raised by a single mom instilled a passion in Denise to help those fighting to rise out of poverty, and advocate for those who can’t advocate for themselves. After completing her internship at Letot Center in Dallas, Denise pursued a career in Management and HR, earning partnership at her firm. Operating alongside a diverse employee culture, she witnessed firsthand the struggle low income individuals without health insurance undergo. After 30 years in the corporate world, Denise returned to her original passion as a CASA guardian ad litem, then to the Hope Clinic Planning Team, volunteering as VC before coming on staff part time. Her desire at Hope is for families to receive holistic healthcare with loving compassion, while never being forced to choose between food, shelter or their health. Denise is married to Bill McMillan. They share four children and six huggable grandchildren.
