Seth was a close friend of my dad Larry Tornek, from Erasmus High school. I most recently saw him both at my father´s funeral in NJ and subsequent Celebration of Life at his home in Miami. All three of my dad´s high school buddies attended: Seth, Ira and Bob. At 85 years young, they were the life of the party, and we enjoyed hearing the stories of the four Brooklyn boys back in the day.
Over the years, starting when I was a student at Penn and later when I worked at Penn Medicine, my dad during visits would invite me to lunch or dinner with Seth, and it was always special: those were rare glimpses into my father´s growing up days.
You will be missed Seth. Say hello to my dad for me, and to both of you: don´t stir up too much trouble up in heaven.

Dr. Koch was a great doctor, in 2023 he operated on my rescued cat with birth defect that was in risk of going blind. That cat is gonna be forever grateful for the gift she received. Meanwhile i get to talk to the doctor about Brooklyn , Erasmus hall Hs i was very familiar too. Very sincere and classy person, he will be missed.
Thank you Doctor Koch.

Seth wasn´t bigger than life. He was life. Seth was a presence.
He imbued all situations, professionally or socially, with a Seth brand of energy and humor. As a trailblazer Seth introduced veterinary specialists to the public market place. In his next life I hope the jokes are funny, the cars sleek and the airplanes high performance. RIP my friend.

So sorry for your loss. I'd only met him once, this past year, when he examined our pet. He was straight forward in his manner, not holding back on his thoughts. I only spent maybe 30 minutes with him, but it was east to recognize that he really was a remarkable man.

I´m so sorry for your loss. He took care of my girls eyes recently and he was just the sweetest and you could tell he loved what he did. Such a loss to any pets he was treating.

To Dr Koch Famly
He did eye surgery on my dog Honey Who is 15 years old. I was unsure of getting the surgery done because of my dog´s age, she had to have her eye removed. Dr. Koch told me he would take very good care of her and God bless him he did.
Thank You Dr Koch you were right, my dog is adjusting with
One eye and running around crazy thanks to you.
Now you can take care of all the animals in heaven may God bless you and your family.

Dr. Koch was so kind and likeable - you couldn't help but love him! He was treating our dog (Winston) for glaucoma and Winston liked him so much. Dr. Koch made a difference, he will be greatly missed. Rest In Peace, my friend.

Seth was one of the most influential contributors to my veterinary medical career. His no none-sense specific details and solutions for with handling procedures and clients kept me sane in vet med. His love of theater brings back so many great memories. Seth - you made a difference, you made vet med better. You will be missed!
