Meet the Mama Bears!

Meet the Mama Bears

Hillary Morgan Ferrer is the founder of Mama Bear Apologetics, a ministry birthed from many sleepless nights. She feels a burden for providing accessible apologetics resources for busy moms on the go. Hillary has her masters degree in biology from Clemson University and is currently working on a masters in apologetics from Biola University. Her specialties are in scientific apologetics, critiques of the Darwinian mechanism, dealing with doubt, and identifying causes and solutions for youth leaving the church. She and her husband have been married for 10 years and minister together as an apologetics team in the local church. Hillary contributes to the ministry as Mama-Bear-in-Chief, coordinating the day-to-day efforts, outreach through Ratio Christi, editing blog submissions as well as writing her own, and recording the Mama Bear Apologetics Podcast with her close friend and partner, Rebekah. She can never sneak up on anybody because of her chronic hiccups, which you can hear occasionally on the podcast.

Rebekah ValeriusRebekah Valerius is the mother of two precocious girls, and she spends much of her time studying and finding ways to quote G.K. Chesterton. She has a bachelors in biochemistry from the University of Texas at Arlington, and worked for several years as a research scientist in the protein crystallography lab at UT Southwestern Medical Center. She is currently studying for her masters in apologetics from Houston Baptist University. Her specialities are incorporating apologetics into culture and literature. Even though her current research interests are in the humanities, she and Hillary made an immediate bond over their shared love of science, and particularly the complex structure of proteins. Rebekah and her husband are entering their 13th year of wedded bliss. She serves primarily as co-host with Hillary on the Mama Bear Apologetics Podcast. You can see Rebekah’s writing on the Mama Bear blog as well as her personal blog

Cathryn Buse is our newest Mama Bear! She is the mom of two adorable and rambunctious boys. She is a former NASA engineer who felt God leading her to leave the workforce and focus on being a mama full-time. Cathryn has taught apologetics for the last 8 years. Her first book Teaching Others to Defend Christianity was published in 2016, and since then she has spent her time teaching her curriculum to a wide variety of church audiences ages 11-84.  She has a bachelors and masters in engineering, and her favorite topics are worldview, pro-life apologetics, and absolutely demolishing materialistic naturalism. With her commitment to both science and equipping moms, she is a perfect fit for Mama Bear Apologetics. She has been married to her engineering sweetheart for 8 nerdy years. Her role at Mama Bear is providing blog content and developing resources for future Mama Bear study groups. You can see her writing on the Mama Bear Blog as well as her website

Hillary Short

Hillary Short

Hillary Short is the senior thesis director at Geneva School of Boerne. She is also our resident Mama-Bear-in-the-field. She is the author of the “Playground Apologetics” series on the Mama Bear Apologetics blog, and enjoys showing moms how to have conversations that matter, wherever God has planted them. She is a connoisseur of awkward moments, forgetting where she left her keys, and making cookies. She is the proud wife of Dr. Howard Short, the proud mom of Jonah Short, and the moderately proud mom of two cats. She is aware that it is confusing having two Mama Bears named “Hillary,” but feels strongly that it is too late to change her name, so we just roll with it.

Alisa Childers

Alisa (Girard) Childers is a former CCM recording artist with the band ZOEgirl. After experiencing a period of profound doubt where her faith was intellectually challenged by a pastor-turned-agnostic, she discovered apologetics. In the wake of this difficult encounter, she slowly pieced her faith back together. Her mission is to now provide the “lifeboat” for others that she wished she’d had during that difficult time. (You can see a video of her story here.) She is happily married and has a beautiful son in a suburb near Nashville, Tennessee where she blogs, speaks, and records on apologetics topics at

You can see Alisa’s writing on the Mama Bear blog, and occasionally hear her on the podcast as well. She is well versed in introductory apologetics, passionate about equipping teens, and is especially educated (through the school of hard knocks) with addressing the theology of Progressive Christianity.

Robin Lopez

Robin Lopez is another fellow scientist, and found a home here at Mama Bear Apologetics. She has her masters in Geoinformation Sciences, and works as a Geoinformation Specialist in Washington, DC. She is an avid student of apologetics, and attends as many conferences as work will allow. She has recently taken over the Audio Apologetics Blog, and has a voice that makes you feel like everything is going to be OK. The Audio Apologetics Blog is a ministry of Mama Bear Apologetics for those who either don’t like reading, or don’t have time to read (like many a mother.)
