The Animal Eye Institute

A native of Cincinnati, Ohio, Dr. Spatola attended Elder High School and soon realized his passion for medicine shortly after graduating from New York University in 2003, ultimately deciding on veterinary medicine as the best fit for his personality and career goals. He graduated from The Ohio State University College of Veterinary Medicine in 2011 with Doctor of Veterinary Medicine and Master of Science degrees. His master’s research focused on canine corneal cells and topical drug toxicity.  Following Dr. Spatola’s graduation from OSU, he decided to further his education through a one-year rotating small animal internship in Charlotte, North Carolina, with Carolina Veterinary Specialists. After a year in Charlotte, he took a one-year ophthalmology internship with Animal Eye Care Associates in Chesapeake, Virginia, where Dr. Spatola was fortunate enough to be offered a comparative ophthalmology residency position in 2013.

In July of 2016, Dr. Spatola completed his residency, passed the ophthalmology board examination, and became a diplomate of the American College of Veterinary Ophthalmologists (ACVO).  He then spent one year in Hampton Roads, Virginia practicing as an associate ophthalmologist with Animal Eye Care of Chesapeake. He finds both the joys and challenges of veterinary ophthalmology extremely satisfying, and feels very fortunate to be with such a progressive and diverse practice here in Cincinnati. His clinical interests are cataract surgery, vitreoretinal surgery, blepharoplasty and autoimmune diseases of the eye. In his spare time, Dr. Spatola enjoys staying active outdoors fishing and camping, exercising, spending time with family, and photography.  He is beyond excited to be back home in the Cincinnati area, and looks forward to providing the community with the best in ophthalmic pet care for many years to come.

Jamie Lembo BS, DVM

Dr. Lembo grew up in the Northeast in Southern Connecticut. She developed a love for both animal care and teaching at a young age. She attended Cornell University in Upstate New York and further developed an interest in veterinary medicine, having studied Biology and Animal Science.  After graduating from college, Dr. Lembo decided to make a big move across the country to pursue her dream of veterinary medicine at the Iowa State University College of Veterinary Medicine. While many areas of veterinary medicine were interesting to her, she felt connected to the study of ophthalmology in all animals, both big and small. During her clinical year of school, Dr. Lembo received the American College of Veterinary Ophthalmologists’ Veterinary Student Award for her interest in and devotion to veterinary ophthalmology. She then moved back to the Northeast to complete a Small Animal Rotating Internship at the Cummings School of Veterinary Medicine at Tufts University in Massachusetts, and shortly afterwards completed an Ophthalmology Specialty Internship at the Long Island Veterinary Specialists in New York.

Dr. Lembo is excited to work with the enthusiastic and dedicated doctors and staff at The Animal Eye Institute. While the study of ophthalmology can be challenging, she finds that working with the clients and pets at The Animal Eye Institute is rewarding and can even be fun! Her current interests include management of corneal disease and surgical corneal repair. While she has spent much of her life in the Northeast, Dr. Lembo is quickly and happily calling Cincinnati “home.” In her free time, she enjoys painting, baking and spending time exploring the outdoors with friends.
