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 Interim 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.
