Marcia Putnam, Secretary
Email: ashdownf@comcast.net
With roots in New England through college, Marcia embarked on a 30 year corporate career in data processing that gave her the opportunity to experience many areas of the United States and Europe. One of the highlights of this experience was a 13 year residency in England which enabled her to live in the countryside on farms and indulge her life-long passion for horses. She has been in the saddle ever since. She is currently living in California and still riding (or trying to!) and is working hands-on with horses on a daily basis. Retirement from the computer business in 2008 has opened new vistas. She has been exposed to the world of disabilities through her daughter who suffered a high level spinal cord injury in 2009. This led to the amazing discovery of carriage driving and US Driving for the Disabled and the incredible people and opportunities involved in this sport.

Jody Cutler
Email: m.jody.cutler@gmail.com
After my husband, Gregg, finished Vet School we moved to southern California and met a retired neighbor who restored carriages and drove a donkey named Ezra (he had come from the pound). It wasn’t long before we were both hooked on driving. I had found something we could both do with our one horse.

One horse turned into the eight Welsh Ponies we now drive and ride and a carriage collection of over 20 vehicles. Both of us drive and officiate in carriage driving competitions. I have served as President of ADS and on the Boards of Directors of the US Equestrian Federation and ADS. I currently serve on both the ADS and USEF Pleasure Driving Committees.

Our Welsh Ponies led to a friendship with Mickie Bowen and the late Sybil Dukehart. In the years when Sybil was USDFD I was able to visit her about 6 times a year due to a job that took me to Maryland. When she decided to sell her gray ponies because they just weren’t big enough for the wheelchair accessible carts or her coach, two of them came to us and were our wheelers for many years.

While judging the open carriage classes at a Morgan show in San Diego, I met Diane Kastama. While she was driving I did not realize she was a paraplegic. Our friendship has lasted many years and led to me going to Breda with her last year.

In addtion to the carriage driving, I have shown dogs and served as a 4H leader for 25 years for dogs, horses and sheep. I am active with Rotary International and serve as my club’s International Chair.
