Meet our staff

From the first time you call our office, attend a fundraiser or a monthly support group meeting, you come in contact with the dedicated individuals who make up our office staff. While each has a unique set of duties, together, they have one goal: to provide you with the information, resources and support that you’ll need in your daily fight with ALS.
