Linda A. Feld


Vice President, Board Member




Linda Feld is from Connecticut and has a background in elementary education. Since moving to Florida in 1975 Linda has spent much of her time as a volunteer for various organizations. Those include Hospice, Canine Companions for Independence and as an Ombudsman in Elder Affairs for the state of Florida. Linda is pictured above with her successor service dog Valentine and is happy to share information with people about the process of getting one of these wonderful service dogs.


Linda is genetically diagnosed with Normokalemic Periodic Paralysis and spent a great deal of time in Germany with the late Dr. Lehmann-Horn learning much about these disease states and the genetics involved. She has made presentations world- wide about this disease and always looks forward to meeting new patients and helping them on their journey.
