Meet the Veterinarians

  • Dr.
    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, athletics, writing comedy and spending time with his wonderful wife Sonali and children Jason and Lauren.

  • Dr.
    Sonali Kothari

    Dr. Kothari was born and raised in Canton, Ohio. After four wonderful years in Virginia attending the University of Richmond, Dr. Kothari attended 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.

  • John Corso

    Dr. Corso brings 15 years of surgical and medical experience to our practice.   A graduate of Ross University's School of Veterinary Medicine, Dr. Corso completed his medical training at Cornell University School of Veterinary Medicine.

    Dr. Corso's dedicated clientele describes him as compassionate with great attention to detail.   Dr. Corso has advanced training in ultrasound allowing us to offer this important diagnostic tool to our clients without having to refer to a specialty hospital, or wait for a specialist to come to us.  

    John lives in Smithtown with his wife, three sons two cats and of course, a dog.


Hear from happy pet owners

  • "If anybody is looking for a veterinarian look no further. All the veterinarians at Townline vet are super caring and informative this staff there is so loving to All Pets. They know the animals names before even checking in and are truly interested in your pet. Every time I bring my puppy there he gets super excited to play with the staff. I've been to a lot of vets in the past and nobody comes close to the care you will get for your pet at Townline vet. Thank you so much to the whole staff for always being there for both Bentley and Triton!!!"

  • "A wonderful place to board. They are caring and kind and we use them anytime we are going away. Go visit and see for yourself their set up. The staff enjoys the companionship of our dog and it lets us leave knowing she is in such good hands."
    Carrie F.
  • "absolutely the best around. Caring doctors and staff... they take great care of my Tibetan Terrier and Im sure she wouldnt be thriving today with out the exceptional care of this team! Dr Karen Urgo is the best... all the techs are fantastic!"
    Sharon R.
  • "Yesterday I made the horrible mistake of cutting my cats skin while trying to cut out a madded piece of hair. My stomach dropped and I immediately felt sick. I had no idea where to take her 10 o'clock on a Sunday morning so I called my sister who referred me to Townline Veterinary group. I we're so grateful to this wonderful staff who took us in immediately with care concern and compassion. They immediately sedated and stitched my poor cat up. And reassured me that she would be fine and that even Groomer's make this mistake sometimes. A few hours later I went back to pick up my poor kitty and today she loves me again. I would highly recommend this office to anyone. I'm even thinking of switching from my veterinarian that I have been with for nine years now. They were so wonderful. I am so grateful to them. Thank you again for taking such excellent care of my Purrly McWhirrly!"

  • "I have brought my both of my dogs to Towneline Veterinary Group for many years and have received nothing but top of the line care for my pets. From one of my dogs having HGE and being hospitalized to recently my dog battling a terrible skin infection and allergies and Dr. Kothari has done everything from blood work to allergies medications and changing his diet to find the best solution for him. I always feel that my pets are in the best hands! Two thumbs up!!! :)"
    Brandon A.
  • "So thankful to have found such a friendly, reliable and trustworthy place to board our dog when he cannot join us on vacation! They are very good to our little guy and keep him comfortable, active and super happy while he is away from home! And most important, I know he is in excellent hands should he need any veterinary care while we are away...makes traveling without him that much easier! Thank you Towne Line!"
    Cristie S.
  • "I love this place! They always have an appointment for the same day when I call and need one. The entire staff is super friendly and know me by name when I come in. Dr. Urgo is so sweet and gentle, I love it when she is in the office. I've been having issues with a stray cat getting into it with my 3 cats (mainly my 2 boys) and when I have to bring them in I always know they're in good hands with Dr. Urgo and all of the staff members."
    Katie S.
  • "Amazing job with our kittens got us in right away when we first found them and again when one of them got bitten by another pet we own. They make them feel very comfortable and made us feel very welcome when we come."
    Meghan T.
  • "Being an employee here, I can say that this staff is very tedious about keeping the place spotless and extremely sanitary! I am a customer here myself and bring my two dogs to the veterinarians here and I would feel 100% comfortable leaving my pets with the boarding services if needed, knowing how professionally they care for the animals here! I plan to continue bringing my pets here as long as I live in this area and would personally recommend this animal care team to anyone looking for a great vet!"
