About Pine Animal Hospital

Your neighborhood Long Beach pet hospital


Steven Manyak, DVM – “Dr. Steve”

Lead Veterinarian
I’m always looking for new treatments and technology, or simple dietary adjustments that have a big impact on my patients

Dr. Steve grew up with a lot of animals in the house: cats, dogs, lizards, cockatiels, chickens, guinea pigs – you name it. As is the case for many children, they were more than just animals to him – they were playmates and friends (and sometimes partners in crime). However, one experience in particular turned him on to practicing medicine. When Dr. Steve was about 8 years old, he woke up to find his beloved dog Lucy (a Beagle-Basset Hound mix) convulsing. The only person who was home was his 84-year-old grandma who did not drive. Helpless, Dr. Steve held Lucy, trying his best to keep her comfortable. Unfortunately, Lucy died in his arms that day, and he made a vow to devote himself to learning medicine so that he would never experience that kind of awful helplessness again.

During and after college Dr. Steve conducted extensive medical research, participating in studies that have led to groundbreaking advances in treating blood and bone cancer, and cardiovascular diseases. With his family’s insistence, he then attended medical school, where he continued to be involved in cardiovascular research in addition to his general medical studies. Although he was intellectually challenged by human medicine and medical research, Dr. Steve felt something was missing. His heart was still drawn to helping animals. Following some soul searching, he decided to switch paths and attend veterinary school.

After working at several veterinary hospitals, Dr. Steve decided to open Pine Animal Hospital with the goal of providing the best possible experience for clients, along with the best possible care for their pets. When he is not at the hospital, Dr. Steve enjoys spending time with friends, playing tennis, hanging out on the beach, and playing with his dogs Mia (a Beagle) and Ollie (a Cavalier King Charles Spaniel).
