our story

Alison Animal Hospital grew out of Alex's conviction that one's work could and should be personally fulfilling, while being performed at the highest level of expertise and service. After college, he experienced corporate culture for a dozen years. But it was not until the loss of his beloved younger teenage sister, Alison, that Alex knew he must follow his heart: to care for animals as a medical doctor. After years of academic preparation, a lot of hard work, and hands-on animal experience as a veterinarian, his goal has reached fruition. AAH embodies Alex's very personal statement about what he has chosen to do for the rest of his life. It is a place where love, caring and professional expertise combine to form a wellspring of vitality for the companion animals whom we adore.

Our practice philosophy is to exemplify medicine's highest values: commitment to service, community involvement, altruism and leadership in and on behalf of the veterinary profession. Our approach is one of science, logic and compassion. Every pet is precious and individual. We are independent thinkers. We are not part of any group or larger entity and have worked hard to resist any contract pricing with vendors and reference labs which might compromise our freedom. We work solely for our patients and their owners. We believe that combining freedom of business with freedom of thought is the prerequisite for the highest level care.

Our brand new, innovative hospital was built to reflect and support the high quality of medicine practiced within it. By incorporating noise management, odor/pathogen control and traffic flow, we have created a calm environment where animals, clients and staff feel comfortable and efficiency is prioritized. Our hospital has been designed to offer the latest technology in diagnostics, medicine and advanced surgery right in the heart of Windsor Terrace.

our team


Dr. Alex Klein grew up in Great Neck, New York with animal-loving parents. As a child, he was a puppy walker for Seeing Eyes for the Blind and endured the continual cycle of attaching to and separating from deliciously adorable Lab puppies. He served as a volunteer EMT/fireman during his high school and college years and always had an interest in medicine, but was also attracted to technology. He graduated from NYU's Tisch School of the Arts with a BFA in 1995. After a dozen years in the fast-paced corporate world, Alex decided to face the daunting and exciting challenge of transforming his career. He attended CCNY at night in order to complete post-baccalaureate coursework and worked on an upstate farm, ultimately leading to his acceptance into Cornell University Veterinary School. Alex has since worked in private practice and animal rescue/shelter facilities, most recently as a staff surgeon and veterinary associate at North Shore Animal League. Alex lives in Windsor Terrace with his wife Lisa, his son Noam and their three cats.


Dr. Susan Ryan grew up right here, in Windsor Terrace. As a child, she often hid stray cats and kittens in her garage, taking care of them until her mother found out. Susan knew early on that she wanted to be a veterinarian, as she always loved caring for animals. While pursuing this dream and obtaining her Associates Degree in Animal Science at Farmingdale State University, Susan worked in a variety of positions within a local veterinary hospital, from receptionist to veterinary technician. Susan obtained her Doctor of Veterinary Medicine from the University of Milan in Italy, with her clinical year at Tuskegee University School of Veterinary Medicine in Alabama. Over the past seven years, she has been a veterinarian in private practice in Brooklyn. Susan believes in a holistic approach when working with her patients and their families. Her deep commitment to them is evidenced not only by her medical expertise, but the time she takes to listen and the comprehensive care she gives them. She believes in the integration of Western and Eastern veterinary practices and given this proclivity, she is a graduate of the Chi Institute in Florida. Susan presently lives in Park Slope with her two rescue cats, Sophie and Shrimpy. She enjoys walks in Prospect Park and biking around the neighborhood. Susan loves gardening and can also can be found walking dogs for Sean Casey.

Noam Landor, Practice Manager

Noam's love for animals started at a young age when her best friend got a dog. Since then, she's immersed herself in anything animal related, from caring for every day neighborhood animals, to African Safari visits and volunteering at Thai Elephant sanctuaries. Her love and passion for animals led her to North Shore Animal League, which connected her with Alex. Noam saw her values come to life at Alison Animal Hospital and has helped build the practice with compassion, empathy and love. Noam currently lives in Queens and has a labrador-sharpei-pitbull mix named Falafel.

Lily Eris, LVT, Head Technician

Lilly's love for animals started early on when she would do whatever she could to feed stray animals as a young child in her hometown of Istanbul, Turkey. She moved to Brooklyn, NY with her family when she was 8 years old and her love for animals never outgrew her. After finishing high school, she joined the US Navy for 4 years, but knew in her heart that she always wanted to work with animals so after getting out of the navy moving back home to NY, she attended LaGuardia Community College and received her degree and license as a Veterinary Technician in 2006. Over the past 9 years, she has enjoyed learning and eventually teaching others about what it takes to be vet tech. She happily joined Alison Animal Hospital in January 2015 and has been very fortunate to be part of a wonderful team. Lilly lives in Brooklyn with her husband and their 10 year old cat Sammy. She loves to travel and enjoys the outdoors.

Jarlin Nunez, veterinary assistant

Jarlin grew up with basically every possible animal allowed in Brooklyn; everything but a snake. She says her three possible career paths were police officer, fashionista, or working with animals. With a heart too big to do anything else, we are fortunate to have her here at Alison Animal where she provides wonderful care for our patients and always comes up with new ways to improve the hospital. Her current menagerie of animals includes Grey, a 116 pound Great Dane, Diego, a Shihtzu, Crumbs, a male cat who steals toys from other pets, Athena, an FIV positive cat and Zeus, her fatty cat. All of Jarlin's animals are rescues.

Brooke McCalley-Faulkner, veterinary assistant

Brooke has been involved and employed with pet rescues and as a veterinary technician for more than 10 years. She spent many years at an emergency facility, gaining experience with a large variety of medical cases, animals and situations. Brooke's family has five cats and fish. Her goal is to specialize in Cardiology and eventually teach at a veterinary school. Brooke is a true animal lover and hopes that her two children follow her footsteps.

Danielle Rizzo, veterinary assistant

Danielle is a lifelong animal lover. Growing up, she always had a house full of pets. Today she has a dog, a cat and a bearded dragon!

Danielle has quickly integrated into the AAH family, and loves spending her days with the wonderful pets that come through the door.
