To Dr. Casler and all the staff:

I just wanted to thank you for all your wonderful care. When I brought Louie in last Wednesday morning, everyone rushed to try and save him, and I really appreciate your genuine concern for him, and your quick response to his critical needs. I know that you all did everything possible, and that every procedure was done with loving care. Thank you so very much.

Sincerely, Shirley

Dr. Casler is my hero.

He took care of my old, sick dog with wonderful understanding of my pet's needs and also of mine. He is skilled, caring, calm and cheerful, with dry humor, just when you most need it. I drove 75 miles to have him treat my pet and I would recommend him to anyone who cares about their pet and wants the best for them.


Dear Dr. Casler,

Thank you for taking care of our Pebbles. Your treatment gave us precious more time we could spend with her before she passed away. We are forever grateful for your dedication to providing the best for all your patients. Pebbles was so brave with all she faced and we are so blessed that we were able to give her her forever home.

Sincerely, Julie-Anne & Fred Shadow & Noah

I want to say thank you to everyone at GAH.

In the early weeks and months of Duncan coming there, everyone at the front desk would cheer when the weight scale revealed some weight gain. I shudder when I recall how thin he was. Then we moved on to conduct the laser treatments on his ear and again, everyone was wonderful, making sure he was comfortable with his goggles on! The big battle conducted was, of course, the series of Heartworm injections. After each injection when we remained there to be sure he was OK, we were made comfortable. I want to thank everyone for allowing us to hang out in your kitchen/lounge area and the kennel staff for making us comfortable in the kennel run. Under the guidance of Dr. Casler and Dr. Ragozzino, we were able to get Duncan through his treatments and back in physical shape after completing the regimen's requirements. He now enjoys his daily two mile walk with the energy and interest of a young dog. I am so fortunate to have him and want everyone at GAH to know how grateful I am to all of you for all your kindness on his behalf.

Sincerely, Jeanne & Duncan

Dear Dr. Casler,

Charlie says Woof! I say thanks from the bottom of my heart!

Take good care, Debbie

Jim and I are very grateful to you Dr. Casler and your staff at this difficult time. We appreciate all that you did for us during this heartbreaking process. Rascal was treated with gentle compassion. We thank you for that.

Jim and Cindy

Jamie and Reception,

I want to thank you and Daisy wants to thank you for the time you spent with me on the phone concerning her heartworm medicine and the danger of going to an outside pharmacy. Thank you for taking the time with us. I am so happy with the staff at Guilderland Animal Hospital.

Thanks so much Love, Marie and of course Daisy

To our dear friends,

Adam and I both just want to thank you all for 13 years of love and wonderful care. We feel so blessed to have had you as our friends and care-takers. Winnie & Clem were always so excited to come in & visit. We always knew they were being taken care of to the utmost. I know you will miss them too. But don’t forget that Lily (our gorgeous Maltese) is still your patient & will be visiting soon!

Fondly, Rebecca & Adam

To the staff at Guilderland Animal Hospital,

We just wanted to thank you for all the love you have given to Aries & all the support that you have shown us over the past months. It has been a tough couple of weeks without her, but we know that she has peace now. Aries always was happy to "visit" with everybody at your office- she loved you all!

Thanks again, Jen, Jerry & Belle

Dear Dr. Casler,

We so much want to thank you for all that you did to help Bruno (and us) during his long period of illness and injury. We thank you so much for your kindness and caring!

God bless you always! Renee & John

Hi Dr. Casler...

Hi to all the nice and caring folks there. I'm Munchie, a most appreciative kitty that you took great care of on 3/31. You made my teeth healthy & "squeaky clean." Sorry I took sooo long to thank everyone, but, you know cats lead a very hectic life; eating, lounging, & snoozing. Takes a lot of energy to do all that; anyway you are all purrrfectly wonderful. Well, bidding you farewell for now! Enclosed are some "kook-katz" me & my sister Annie who thanks you too!

Very meowy yours, Munchie & Oops, Diane also (she's my mom!)

To all the girls & staff who pretty much run the G.A.H.!

You are all awesome & we just wanted to say thanks for all you did to help "Prozac" & make a very difficult time a little easier for us!

Thanks Again, Andi & Kevin & "Beano" & "Buckshot"

You're so kind,

We always have felt so secure and confident with the care you always gave Swazi.

Carol and Paulette

Thank you,

I can't thank all of you enough for being there and staying late for me in a time of crisis. I thank God you were there and so helpful. Andi is doing well thanks to wonderful people like you.


Dear Dr. Casler and all the GAH staff,

Thanks so very much to all the staff for your support and compassion on that very difficult day when the time came for us to say goodbye to our favorite pup. Dr. Casler, your professionalism, expertise, and kind guidance were most appreciated, and provided us with solace and strength.

We know how much Zeus loved visiting all of you. GAH was his home away from home. Whenever we were preparing to go away on a trip, and we were unable to bring Zeus, we were comforted knowing he would be well cared for at GAH. We used to tell Zeus it was time to go to the "Doggie Hotel." He always knew exactly what we meant. We even had a little jingle we would sing about it. :) Zeus would wag his tail and prance to the door (in his younger years), so excited and ready to go see all his friends.

Thank you so much for being so good at what you do! You provided Zeus with some very happy times during his very full 13 years, and we are grateful.

Sincerely, Maribeth and Kyle

Your wonderful medical care means so much!

Your wonderful young ladies were so good to our cookie! We love the tender loving care that you gave to Cookie. He looks so beautiful and he smells delicious. Cookie says you girls are the cats meow.

We love you, Sue, Greg and Cookie

Thanks to all of you...

Thank you all for being so kind every time we come to see you. My new stray with 1 blind eye is now a member of my family and yours – that's how it feels.


To our friends at GAH,

My family and I can’t thank you enough for the loving care you gave to Tucker, not only as he passed, but over the last 10+ years as a GAH patient. We always knew he was receiving the best care, especially when he boarded there. Tucker was a very special dog, truly part of our family. We all feel very lucky to have been his human family and will miss him forever.

Warm Regards, Maribeth & Rick


Thank you all for the great, loving care you took of Thor, through sickness and health.

You're an excellent animal hospital in whose care I will certainly entrust my next little furry companion when the time comes.

With Sincerest Gratitude, Leroy

Dr. Casler & Staff

Thank you from the top, bottom & middle of my heart for taking such good care of my "fur babies" Raiden and Takara. I am forever grateful for having such a caring doctor & staff for my pets. I appreciate all that you do for us.

Happy Paw Prints, Maria

Thank you so very much for the love and care you give our four legged children. The knowledge and respect you give to us , two legged and four, will stay in our hearts always.

Thank you for peace of mind and great caring.
