Edwin W Laffey Jr.


Wynn attended the Lawrenceville School and Columbia University before pursuing a career on Wall St, starting in 1970 with Chemical Bank, and culminating with his co-founding of First Money Managers International in 1982 (a concern no longer extant). Also during that period he served on the boards of 313 East 10th St. Corp., Collette Mfg. Co., and the Children of Bellevue Hospital. After taking some time off, but looking to re-engage with the charitable sector, particularly with an enterprise that was young and as much in need of sweat equity as donations, Wynn was introduced to Mead Welles and the newly created A Leg To Stand On. At first his involvement was primarily passive due to personal time constraints, but that all changed when he took on a more active role following the earthquake in Haiti in 2010. After visiting the Hôpital Albert Schweitzer (HAS), 2 1/2 hours north of the capital, in 2011, Wynn joined ALTSO's Advisory Board. Wynn is also currently involved in the activities of another not-for-profit, PUPPIES BEHIND BARS, an organization dedicated to the raising & training of service dogs by prison inmates for the primary benefit of those service men & women who suffer from ptsd &/or have limb disabilities. He also takes a "puppy" once a week to the New York City District Attorney's Family Justice Center to assist in a pilot program to help victims in battered families adjust to and accept their trauma as well as seek justice.



Gabriella Mueller Evrard

Executive Director

After traveling extensively throughout developing countries in Latin America, Gabriella decided she wanted to do something to help the many children she saw begging for money or food. In 2006, she signed up to volunteer at A Leg To Stand On. Now the Executive Director, Gabriella is humbled to have overseen the organization’s growth from three programs to over 10 programs in six years, and to continue cultivating relationships with supporters as passionate about A Leg To Stand On’s mission as she is.

A.J. Warco

Director of Programs

A.J. joined us in 2009 after working on humanitarian projects throughout both South and South East Asia. While abroad, he learned firsthand how many children with physical disabilities miss out on the opportunity to attend school, are labeled as family burdens and often abandoned to fend for themselves. Upon returning to the States, his experiences led him to learn more about suitable prosthetic and orthotic technologies and physical rehabilitation programs in the developing world. He now develops and manages our program partnerships, frequently traveling to programs across Asia and Africa.

Beth Ann Hemming

Director of Development

Beth Ann, a 2013 transplant to New York from the mid-west, is the newest member of the ALTSO team. Having a sister with disabilities, she has always had a passion to advocate for children in need. This and her experience working with orphans in Ethiopia give her a drive and excitement to see even more children receive free orthopedic care.
