​ASCF staff
​

Monica Agostinelli
Chief Executive Officer/Executive Director
Monica is a transplant from “Corporate America” whose heart for service has consistently pulled her toward the nonprofit sector. Her strong business acumen, strategic financial planning skills, experience leading capital campaigns, background in bioengineering and personal passion for ASCF’s mission uniquely prepare her to serve ASCF as we grow and evolve.  Having multiple close encounters with family members and friends impacted by the life-changing diagnoses of cancer, she is inspired by the work of ASCF.  Here she hopes to continue to build and expand the reach of the organization and the resources that are available for those seeking a shelter from the storms that cancer can wage on a family.   
 
Most recently, Agostinelli worked as Vice President of Internal Audit for Waste Management. Monica and her husband Chris have two children - Aiden and Annalise - who are the entertainment and joy of their lives.

Shellyn Shoenthal
Director of Development and Communications
All the way from Pittsburgh, PA Shellyn has called Houston home for five years. She comes to ASCF with over 20 years experience in communications, development, marketing and community relations. She is thrilled to be serving cancer families. In 2012 Shellyn received the news that she had acute lymphoblastic leukemia (ALL) and immediately began a 2.5 year journey to receive the very lifesaving treatment so many who depend on ASCF come to Houston in search of.. While she has served the cancer community in many ways since her diagnosis, her role here is especially close to her heart and she will strive to bring ASCF to new heights, so that even more families can find the stability, shelter and support they deserve. 

When Shellyn is not being a champion for ASCF, she can be found volunteering at her children's schools, with BSA Troop 505, in her parish and with various other community causes. She also never misses an opportunity to spend quality time with her family -  husband Dan, son Jake and daughter AJ. 

​Madelon McGrenera
Director of Operations
An Austin native, Madelon McGrenera later graduated from Texas Tech University and eventually her family made their way to Houston now calling H-town home. Madelon served in a number of volunteer roles for ASCF prior to joining A Shelter for Cancer Families' staff. Her vast experience, professional polish & attention to detail have enabled Madelon to provide a much needed level of support to ASCF. In her role with ASCF, Madelon helps oversee the implementation of ASCF's strategic approach to fundraising which includes major gifts, annual fund, planned giving, corporate donations, grant solicitation, capital campaigns, special events & in-kind resources.  

When not working for ASCF, Madelon & her husband Ryan can be found cheering for son Grady on the ball field or supporting daughter Reese in her acting & singing endeavors.
