Susan Faitos, M.A., L.M.F.T.

The Board of Directors of The XLH Network, Inc., is delighted to announce that Susan Faitos has been named Executive Director of the Network. Susan has spent over thirty years in the social work and mental health fields working primarily with nonprofit, community-based organizations, and she started her own 501c3 nonprofit organization when she was just twenty-five years old. Currently she works part-time as a Clinical Director of Behavioral Health Services for a local agency in Santa Cruz, California.


Susan has been a familiar face at Network events over the last few years and she was responsible for organizing last year's Symposium/PFDD in Baltimore. We are grateful that she has chosen to contribute her wealth of experience in the nonprofit world to the Network and our community. Susan was diagnosed with XLH at eighteen months of age, so she also brings a lifetime of understanding to the position.


We are excited to continue to grow and to commit to our community of patients under Susan’s leadership. You can reach her at ExecutiveDirector@xlhnetwork.org.

Geoff is a Chief Scientist at BAE Systems, FAST Labs with a focus on undersea systems and technology.


Christopher Younger: Chris is currently serving a three-year term on the Board of The XLH Network, Inc., and he is chair of the Technology Committee. He joined the Network in 2000.

He also has a love for music, plays guitar and mandolin, and in his spare time he and his wife front a band, performing regularly at local clubs and festivals.

Sara Show: Sara is currently serving a two-year term on the Board of The XLH Network, Inc. She and her family reside in South Dakota. She joined the Network in 2016, after her daughter was diagnosed with XLH, later determined to be a spontaneous case. Sara is an Associate Attorney with a private litigation firm and has had the privilege to work for a Senator, the US Attorney in South Dakota, a State’s Attorney in South Dakota, and several Judges in South Dakota State Court. She enjoys spending time with her husband and their daughter, who has XLH, and son, who does not have XLH. She is also currently a member of the fundraising committee for the Network.


Sunindiya Bhalla: Sunindiya is excited to join the board to more formally bring the skills she has from working in the nonprofit world for many years - including fundraising, policy, and impact work - to ensure the growth and ongoing success of the Network. She is particularly interested in ensuring that teens and young adults - especially those with spontaneous XLH - have strong support in their journey into adulthood. Besides working and volunteering her time, she loves going to the beach, being on my porch with coffee and a good book, and spending time with my mom. She is also hoping to adopt a baby sometime in the near future.


Sarah Das: Sarah is new to the board this year, but not new to XLH. She has a daughter with a spontaneous case of XLH. She feels fortunate that she was able to get her daughter diagnosed and treated early in her life, and her goal as a board member is to reach out to other families and advance awareness and education of XLH . Her professional background is in corporate finance, and she volunteers in her community as a softball coach, at her children's school and at various military veteran's events. She resides in Connectidut with her husband and daughters.


Marian Hart: Marian is from Zionsville, Indiana and is currently Clinical Research Leader at Indiana University Division of Endocrinology where she has been since 2002.   She began working with XLH patients around 2010.   During this time she has learned so much from her patients and colleagues across the world.   She believes that knowledge is power and that education of patients and family regarding their condition is a top priority.   Her spare time is taken up with two teenage boys.   


Jason Grant: Jason lives in Columbia, MO with his wife Lisa and their two children. He is serving a three year term on the board of directors. Although XLH has come with struggles, his family and the connections made in the XLH network have afforded him the opportunity to connect with a community that understands the hardships, and support needs of living with a rare disease, and this encourages him to do the same for others.  XLH taught Jason the importance of empathy and compassion, which he is fortunate to use in his work as a nurse. Jason enjoys spending free time with his family, being active, playing board games, and traveling. He looks forward to using his passion for learning and community to strengthen communication and support for families encountering the challenges of XLH.
