Our Staff


staffimage_1.pngDr. Marc Gurtman

In 1991, after a few years of uninspired practice as an attorney, Dr. Gurtman decided that he was tired of working with animals :) and pursued a career in veterinary medicine. A 1998 graduate from Cornell University’s School of Veterinary Medicine, Marc has special interests in surgery and oncology.

Dr. Gurtman enjoys the challenges of difficult cases and is lucky to have friends that are specialists in various veterinary disciplines to call upon when needed.

Marc enjoys guitar, ice hockey, writing comedy and spending time with his wife Sonali and children Jason and Lauren.

Dr. Sonali Kothari

Sonali ithaca

Dr. Kothari was born and raised in Canton, Ohio. After four wonderful years in Virginia while at the University of Richmond, Dr. Kothari decided to attend veterinary school at Ross University on the beautiful island of St. Kitts. She completed her final year of clinical studies in Louisiana at LSU and graduated Veterinary School in 2004.

Animals respond to Dr. Kothari’s warm and caring demeanor. Perhaps they sense that “she’s not from around here”.

Driven to offer the “best” medicine, Dr. Kothari will leave no stone unturned in diagnosing challenging cases. She has a special expertise in dermatology and has helped many dogs that had been suffering a life of discomfort due to skin ailments.

Sonali enjoys taking long runs, swimming, tennis, traveling and eating! Although she loves all breeds, Dr. Kothari has a special place in her heart for the small flat-faced kind. Look for Kiwi, Ponzu, Miso, Gnocchi and Maui as evidence when you come visit our practice.

Dr. John Corso


A graduate of Hofstra University, Cornell University School of Veterinary Medicine (clinical training) and  Ross University School of Veterinary Medicine Dr. Corso brings 15 years of surgical and internal medicine experience to our practice.

Dr. Corso strives to provide the best care and service for his patients.  "Every animal I treat is comparable to caring for my own pet.  Attention to detail and speaking and listening to pet owners is critical to diagnosing issues.  I'm also very excited to work in a facility that has state of the art equipment, which is imperative in this industry".

Dr.  Corso is a member of the Long Island Veterinary Medical Society, American Veterinary Medial Association and accredited with the United Sates Department of Agriculture/Animal and Plant Health Inspection Service, Veterinary Services, NY and the New York State Department of Agriculture and Markets Division of Animal Industry, NY.

A Smithtown native, Dr. Corso's childhood pets included dogs, cats, horses, ferrets, goats, turtles and exotic birds.  His early love of animals and hands on experience in caring for his pets nurtured his passion to become a veterinarian.   John still resides in Smithtown with his wife of 15 years,  three sons, one dog and two cats.  


Samantha Simon

Sam graduated from the Suffolk Veterinary Technician program in 2013. She enjoys being in the operating room, closely monitoring anesthesia during surgery, assisting the doctors with their patients as well as preforming dentistries. She has always gravitated to all types of animals but she has a weakness for Shiba Inu dogs, as she and her husband have two; Huey & Floki.

I have been a proud member of the TLVG family for about 3 years. When I’m not helping you and your pet I am teaching math or working on my Master’s Degree in Mathematics Education. In my free time I love going to the beach, spending time with my family and drinking coffee.

Let’s see.. my favorite Ralph’s flavor is definitely the blue raspberry. I’m attending saint Joseph’s college with a psychology major and I started working at TLVG in 2016. I love working with and helping all of the animals that come for day care, boarding, or even just for appointments :) OH! and I also have three dogs named Quinn, gimli, and wolfie and a fish named Bruce!

I am a junior zoology major and chemistry minor at SUNY Oswego and I plan to apply to vet school this year. I want to work in rescue/ shelter medicine as well as wildlife/ aquatic rescue medicine.
