I am very grateful for Dr Thomas’ soothing and gentle presence as we said goodbye to my beloved cat Keith, and especially for the respect with which she treated Keith even after he was gone. This was my first experience with at-home euthanasia (as opposed to at the vet’s office) and I heartily recommend Dr Thomas and Coda Pet.

We recently had to say goodbye to our 14.5-year-old dog, Bear, and chose to do so in the comfort of our home. I’m so grateful that Dr. Angela was the person who helped us through it. She was incredibly kind and gentle with both him and us from the moment she arrived. More than anything, she made us feel like there was no wrong way to do any of this. We felt safe asking questions, crying, grieving, and just sitting on the floor together with Bear while she worked around us in our cramped living room. She asked questions about who Bear was, his favorite treats, his personality... Nothing felt clinical or awkward, and nothing was rushed. She explained everything that was going to happen and what we could expect physically and timing-wise. After Bear took his last breaths, she even stepped outside and let us have as much time alone with him as we needed. The back of her car was set up with soft lights and thoughtful little touches that made even that part feel cared for. She was so gentle with him, and it just meant so much to me to know he was in good hands. Saying goodbye to our best friend of 14.5 years was incredibly painful, but she made the experience as peaceful and gentle as it possibly could have been. I’m so thankful for the care and dignity she showed Bear, and for the way she guided us through such a difficult day. I would recommend her without hesitation to anyone having to make this decision.

Dr.Gregory-MacDonald assisted us with transitioning our best boy Tommy across the rainbow bridge. We have been there several times before, but this experience was the most personal and special process. Her compassion and manner were nothing short of amazing and made the difficult time much easier. Thank you forever.

He was simply amazing. He made this horrible time in our lives a beatable one. His demeanor and soft-spoken manner definitely helped us do what we knew in our hearts was best for our 18 year old Cockapoo. He was able to get us to remember her best times and made us feel that this decision was one that was best for dusty. Thank you Dr. Litwack. You will not soon be forgotten. Dan & Martha Battisti

Despite the circumstances that brought us to Dr. Angela De Villa, she was absolutely amazing. She was calm, compassionate, and incredibly understanding throughout the entire process. She followed both our cues and Daisy’s, allowing us to move at whatever pace felt right without ever making us feel rushed. During an incredibly difficult and emotional moment, her kindness and patience meant more to us than I can put into words. I’m so grateful Daisy was treated with such gentleness, dignity, and compassion in her final moments.

Putting my soul cat, Snuggie, to sleep was the hardest thing I have ever had to do. I live alone, my family is out of state, and I was terrified of facing that moment without the people I love physically there with me. From the second Dr. Briell Dzierga walked into my apartment, she felt less like a veterinarian and more like a personal friend who had come to help me through the worst day of my life. She cried with me. She laughed with me as I shared stories about Snuggie. She hugged me. She gave me time alone with my baby whenever I needed it. She let me keep my mom on FaceTime throughout the entire process so she could be there with us too. She also helped me understand how to include my kitten in the process so she could see and understand that Snuggie was no longer with us. That was something I never would have known how to navigate on my own, and I am so grateful she thought about not only me and Snuggie, but her too. Dr. Dzierga explained everything as we went and moved at our pace. Nothing felt clinical. Nothing felt rushed. She took pictures of me with Snuggie that I will treasure forever. She even helped me get my baby's paw print on my ink pad so I could have that keepsake. She shared her expertise, but she also shared her own understanding of grief and loss in a way that made me feel so much less alone. I truly do not know how I would have gotten through that day without her. Afterward, she sent me the kindest, most personal card. It was so specific to me and Snuggie that I knew she had genuinely been listening to every story and memory I shared with her in between sobbing. I can barely read it without crying, but I will keep it forever. There are some people you meet during the worst moments of your life who you will never forget. Dr. Briell Dzierga is one of those people for me. She is an angel, and I will never not recommend her. Thank you, Dr. Dzierga, for giving Snuggie such a peaceful goodbye and for taking care of me with so much compassion while I said goodbye to my best friend. I will be forever grateful for you.
