Help Brian raise funds for Electrical Stimulator

Brian was diagnosed with MS in 1998. He has a limited income as he has been on disability since 2012. His walking has severely deteriorated this past year. His Dr has highly recommended him getting an FES which is a Functional Electrical Stimulator. It helps prevent foot drop. It will help him to be able to walk. He really enjoyed the outdoors such as hunting, fishing  etc. and he tends to get depressed as he isn't able to work or do the things that we take for granted. He has a very compassionate heart for others and takes care of his elderly parents as far as driving them to appts, grocery shopping,  and other errands. We (brother, Marc and sister, Lisa)would love to give back to Brian. His insurance will not cover the walking aid.  I am asking for your help with the financial burden  whether big or small. Thank you!
