Sue Marshall, DVM
Celebration of Life

We lost a dedicated local veterinarian and dear friend on Saturday, March 12 ,2016.  For those of you who didn't know Dr. Sue Marshall Fallon, she came to the Tri-Valley area in 1990 after graduating from UC Davis vet school. The next year she began volunteering and sharing her medical knowledge with Valley Humane Society since she felt strongly about the need to spay/neuter to prevent overpopulation and thus reducing euthanasia at the county shelters.

She was the medical consultant to the team that started the Just Like New program to help pet owners with an urgent medical need when they could not financially afford the care. She started Feline Medical Center in Pleasanton a decade after arriving in this area. For the past several years she has been a strong supporter of Paws In Need whose programs include the Just Like New program and a Spay/Neuter program which were Dr. Sue's passions.

The following is from Beth Sackett, Dr. Sue's sister-in-law:

It is with a heavy heart that we tell you that Sue Marshall Fallon went home to heaven on Saturday March 12th. She is now pain free and at peace. We thank each of you that has loved and prayed for Sue and our family during this journey. We have all been blessed by knowing her and she will be missed by everyone who loved her.
You are invited to join us as we celebrate the life of our beloved Sue at Trinity Baptist Church in Livermore.

Alex Clifton

Currently a student at Cal Poly in San Luis Obispo, Alex is a seasonal employee, working with us when she's not in school session. We are thrilled to have her for the summer!

When not in school or at work, she enjoys photography, hiking, and working with animals (she raises and helps with breeding pigs!).

Hospital Cat

In 2014, Bruce’s owner was contemplating whether or not to euthanize due to his age and the owners facing a big move into a new house.  Bruce was an outdoor cat and according to the owner wouldn't use a litter box and she didn't want to upset him by moving him indoors.  With some FMC lobbying (because we all fell in love with Bruce), the owner agreed to sign him over to us and that's how he became one of our resident hospital cats!  

Hospital Cat

Elle originally came in with severe dermatitis, FAD, eosinophilic dermatitis and the owner could not do treatment and elected to euthanize.  We all fell in love with Elle’s personality and knew we could treat her back to health and couldn't think of euthanizing her! So, we asked for owner to sign her over to our care.  Gratefully, with antihistamines and regular flea control Elle was treated back to health and loves being an FMC resident hospital cat!
