She is one of only 80 board-certified feline specialists in the U.S., and is a member of multiple local and national veterinary and feline organizations.

Dr. Rubenstein and A Cat Clinic also started the Aurora’s Angels Fund to help support cats in the Germantown/Boyds area with needed veterinary care.

Ann serves as our administrative assistant at A Cat Clinic. If you call our clinic and hear a lovely British accent, you’re speaking with Ann! She grew up with cats and loves seeing all the cats come though the clinic. Many of our boarders spend time keeping her company while she works. She has a husband, two wonderful children and two dogs at home.


Vicki is our Registered Veterinary Technician, having obtained her AAS in Veterinary Technology from Broadview University in Utah in 2013 and receiving her RVT registration in Maryland in 2014. She also was a professional pet groomer for 6 years. She moved to Maryland after graduating from Broadview, and we are so fortunate to have her with us at A Cat Clinic! Vicki has four cats at home (Juno, Canary, Rufio and Fry), and she loves working with our clients’ cats and getting to know their unique personalities. Her favorite quote is, “Dogs come when they’re called, cats take a message and get back to you later!”


Christina became a member of the A Cat Clinic team in March, 2017.  She is mainly at the front desk, but will also help out with the patients.  Her prior animal experience includes several years doing grooming. As a child, she was not allowed to have a cat, so that was the first peNext page›t she got when she became an adult.  She says, “As every cat owner knows, nobody owns a cat!”  Christina has three young children, and when she has a free moment enjoys reading.  She shares her home with one kitty, Chompers, as well.


Sarah joined our team in August, 2018 as a receptionist.  A Montgomery County native, she graduated from Montgomery Blair High School in Silver Spring. However, she has traveled extensively, and spent time living abroad (her husband is from England and her mother from Thailand). Sarah’s previous animal work experiences involved caring for dogs, at a dog daycare and at a large boarding facility.  She has also volunteered to foster dogs with three local dog rescues.  Yet she has become a “converted cat person”. She said one day in her adult life, “the light in my head suddenly switched on!” Now Sarah feels strongly that everyone should have a cat, at least once in their life.  She shares her home with a black cat named Iggy, who she adopted in 2017.  He came from a feral colony outside of Baltimore, although he had likely been someone’s pet.  In her free time Sarah enjoys music and piano, and traveling.

Samantha (Sam)

Sam graduated from the University of Maryland, College Park in 2013, and works with us mostly as a Veterinary Technician.  She is looking to fulfill her goal of becoming a wildlife or exotic animal veterinarian. Prior to joining our team, Sam interned at a small animal veterinary hospital, assisted an equine veterinarian, and volunteered at a wild animal sanctuary. She lives on a farm with 6 horses, 2 dogs and several barn cats. She has a special affinity for working with cats, which she admits are her favorite.


While attending Frederick Community College’s Veterinary Assistant program, Ian learned about A Cat Clinic and came to us to do a clinical internship for the program.  After he completed his internship, he joined our team as a part time Veterinary Assistant, and has worked his way up to full time Veterinary Technician. Ian’s passion for cats stems from the time when, as a young boy, his mother surprised him with a little Bengal kitten.  She was wrapped in a pink blanket in a box, and he recalls her being so small and soft.  That was the start of his love for animals!  Currently, with his 2 brothers and 3 sisters, he shares Lila, a Plott Hound, at home.  His hobbies and interests include fantasy and science fiction, novels, video games, and of course, animals!


We are so fortunate that Alex has brought her five years experience at a cat hospital in California with her as a Veterinary Technician!  Alex joined our team in November, 2018.  Her background is varied, receiving an  Associate’s Degree in Cosmetology from Montgomery College before she became a veterinary technician.  She has had cats in her household all her life, so it was an easy switch over to veterinary medicine.  Alex especially enjoys assisting with surgeries and doing dental cleanings for our feline patients, and loves that her job allows her to help cats stay healthy.  She also enjoys learning more about cat health every day.  Currently, she shares her home with one cat, Salem, who was found by a former staff member stranded out in a storm!  And she also has one dog, Renly, a 5 year old terrier mix.  In her spare time, she enjoys reading, going to the beach, and traveling to new places.


Joining the A Cat Clinic team in September, 2019 as a full time assistant, Lindsey is busy making sure all the cats are well cared for and the clinic is in good order!


Zach has a degree in Culinary Management, so he’s an example that cat lovers come from many different directions!  Zach started with A Cat Clinic in December, 2019, joining our Reception team. He’s excited to be here because he loves being able to help others who love cats as much as he does.  He and his family have always shared their home with at least one cat, his current cat being Winston.  Zach says his first cat was very timid, but he worked hard to gain her trust until they became bonded for life.  In his free time, he enjoys reading, baking, and sewing.  He is very passionate about saving the environment and our fragile ecosystems, and he tries to do everything he can to help in various ways.


Kim has been with A Cat Clinic since Aug 2016 as an assistant.  She graduated from Montgomery College with an Associate’s Degree in Life Sciences and is currently pursuing her undergraduate degree at the University of Maryland for Animal Science.  Kim has volunteered at a local senior pet rescue for several years, and she is currently volunteering at the National Zoo in D.C!  With her busy schedule, Kim has no pets right now, but hopes she will be able to share her home with a 4-legged friend soon.  In her spare time, she loves traveling and has been practicing watercolor painting and sewing.


Currently in college at University of Maryland, College Park, Maryann started here at A Cat Clinic in August, 2016 as an assistant.  She will help us out when she is home during her college breaks.  At home she has three dogs and one turtle, and likes to foster dogs.  She has also worked on a farm where one of the barn cats would always follow her around, and that helped foster her love of cats.  She likes working at A Cat Clinic because she appreciates how all the staff truly cares about their feline patients.
