We started using this facility almost a year ago when our prior vet retired.. We have used them for non-emergency surgery on our cocker that went very well. (Teeth cleaning and ear cleaning). This is a good size operation, with about eight vets, a sizeable and knowledgable support staff, and good appointment hours up to 8PM on weekday evenings. Amazingly, they have appointment hours all day Saturday and all day Sunday. Best of all was their ability to handle an emergency. On a weekday, at about 7PM, our dog was in distress...unable to void in any way, and not moving. We were scared. We called Clocktower and said it was an emergency. They took him right away (small emergency extra charge, that is fine). He got immediate treatment from one of the vets, and immediate X-rays, proving that it was only a minor muscle problem fixable with medications. The doc explained all this in great detail and calmed us. He showed us the X-rays. We got medications right there, and were released. They said call any time, at all hours if any problems. They then called us the next morning to see how our dog was doing. We are extremely happy with there work, very confident of their abilities, pleased with their personal treatment, and glad they are nearby. Located in Herndon, right off the Toll Road, Elden Avenue South. Look for the Clocktower! read more

My wife and I recently adopted 2 cats and unfortunately one of them had an intestinal blockage and needed emergency surgery. A week later that same cat got an infection and needed to be seen immediately due to very high fever and clocktower was incredibly accommodating both times. We didn't have an appointment and the front office staff told us that no appointments were available until the morning. Dr. Riedel was working that night and was concerned with the situation so told us to bring our kitten in anyways and treated the fever (she had also performed the surgery a week prior). I can't tell you how happy we have been with Dr. Riedel in particular, but the entire staff at Clocktower. Everyone has been as friendly as can be, and they all seem like they truly care about the kitten's well being. One of the nurses was hugging my wife the other night and she hadn't even been involved with our cat. Dr. Riedel has called us to follow up multiple times without really needing to, but she clearly just cares about the kitten's health and also I feel like she cares about how we are handling it as new owners. We started coming to Clocktower because our local patch website had a number of positive reviews, and I can't say enough how happy we are to be bringing our cats here. I would certainly recommend this vet to any pet owner. read more

About a year ago I adopted a pitbull mix. He is the sweetest boy and I love him, but soon after I got him he started acting really lethargic and coughing a lot. I took him to Clocktower on a friend's recommendation and the vet quickly diagnosed him as being positive for heartworm. I had heard about heartworm, but I had no idea what a big deal it is if your dog actually gets it. I am happy to say after a course of treatments at Clocktower that my sweet boy is now heartworm free but through all of this I learned a ton about the disease. For example, if you get your heartworm preventative online it's not guaranteed by the manufacturer. And while it may seem expensive to buy the monthly preventative it's a whole lot cheaper than treating a dog who gets heartworm. Treatment is a big deal and involves several days of hospitalization, and has to be followed by a long period of rest and monitoring. It's serious stuff. The vets and staff at Clocktower were so great throughout this whole ordeal, and I am so grateful to them for everything they have done for us and will continue to do for us, since we definitely plan on keeping them as our vet! read more

I started taking my two dogs (a lab and a pug) and two siamese cats to Clocktower Animal Hospital about 4 years ago when I moved to the area. I checked out other vets in the area (Herndon/Reston/Great Falls/Sterling) and settled on Clocktower and am so happy I did. Anyway, I have been in a lot with my pets for everything from routine annual exams and vaccines to pretty serious things and an emergency. The doctors are fantastic, all of them, and the staff up front and the ones who work with the doctors in the rooms/back are all really compassionate and know their stuff. They help me understand all my options and are VERY professional. My dogs love going there because they get treats every time, and they are really gentle with my cats and help them feel as comfortable as possible. The receptionists greet us by name when we walk in the door. I have had to use the late and weekend hours occasionally and find this to be extremely helpful. Overall, a WONDERFUL animal hospital...definitely consider Clocktower if you are not wow-ed by your current vet. read more

What would you do when you see your veterinarian sitting on the grass and playing with your neighbor's dog in their front yard? His response to my then-neighbor," I was on my way home and was thinking about 'Fido' and just stopped by to see how he's doing." That's Dr. Chris Carskaddan, owner and one of the eight veterinarians at Clocktower Animal Hospital. And this was not an isolated incident. Some years ago I had an emergency with my dog. I called and when I was passed over to Dr. Carskaddan, he says, "I tell you what, I'm leaving to go home, how about if I stop by your house and check him out? It'll be faster." He came and spent almost 45 minutes with me and my dog and had the supplies to take full care of him. House calls? They still exist. An incredibly polite, intelligent and humorous veterinarian with a sincere love and advocacy for animals. I highly recommend anyone in the area to see Dr. Carskaddan for the healthcare of your pet, especially if you have a dog. read more

Staff provided loving, top quality care for our two cats from 2004 to 2010. Both cats had one or more chronic conditions and required frequent (often weekly) technician visits. The front desk and technicians are always professional and friendly. The doctors are thorough and provide complete explanations on observations and treatment. They are available as needed, and they do follow-ups by phone. The facility is always spotless and odor free, and it has top-of-the line diagnostic and treatment equipment. When it became suddenly clear that one of our cats, George, needed to be euthanized, we arranged to bring him in so any of the on-duty doctors could do the procedure. But the staff notified his primary doctor, Doctor Carskaddan, who drove in from home on his day off and took charge. He, his technicians, and the front desk were supportive to the end. Clocktower's staff was a major factor in maintaining the happy lives of our cats who lived to be 19 and 21. Raleigh and Irma Moses read more

Words cannot express my recommendations and gratitude to the staff of Clocktower Animal. My 15 year old Silky Nikki had been seeing Dr. Carskaddan, who extended her life by years by catching her tracheal and heart murmur in its early stages and working with me on treatments. He was always a warm and caring person who got me through some tough times and for whom I will always be eternally grateful to. Dr. Carskaddan was kind enough to give me his personal cell and small address if I ever wanted to reach back out to him or have my new vet contact him. The rest of the Drs and Staff were also instrumental in saving Nikki's life when she had a heart attack, and moved her on to a new heart medication and she was active again after that. We took our lab and cat to therm over the span of 6 years. It was difficult for me to not be able to take our pets there anymore as we moved to Tampa, FL. They are the best I have ever dealt with. read more

I originally wanted to make an appointment to get a 2nd opinion for my dog and Dr. Vincent was assigned to me. She was very caring and took the time to read over the records of the previous doctor from another animal hospital in the area. She suggested a procedure and set up what was necessary to get another doctor involved. She was very good at communicating with me and if I call and need to speak with her, she is usually available or will call back shortly. The people on the front desk are very good and I have never been asked if I could be put on hold when I call. I mention this, because I was put on hold often at the other hospital and had long waits to hear back from the doctor because she was so busy. My dog now has Dr. Vincent as her doctor and I plan to switch my cats over to her also. There appears to be no extra charge for the great service, as the prices are the same as I was paying. read more

My little 4 year old dog was acting weird and walking around with his back arched and seemed to have a hard time pottying. Later he seemed too weak or uncoordinated to climb the steps. He seemed to be going down hill fast, so I rushed him to Clocktower Animal Hospital in the middle of a Saturday with no appointment. They graciously fit him in and he saw Dr. Schneider. She figured out almost immediately that the issue was a neck injury, not a digestive system (poop) issue like I thought. She had her vet tech give him a red light laser treatment to speed healing, a shot for pain, and take home meds. He is doing much better today. Thank you CAH for the great care and kindness for my ailing pet, Everyone was so gentle and caring with my little dog. Their excellent care was much appreciated. :-) read more

I take my dog to Clocktower Animal Hospital and while the vet and vet techs are absolutely amazing, the front desk staff leaves something to be desired. While some of the ladies are very friendly, your experience may be quickly ruined by one of their less compassionate receptionists. Again, you would have a very difficult time finding a better vet than Dr. Carskadden but if making an appointment means dealing with one of their more ornery desk attendants, I fear I will soon be searching for a new vet. I believe that empathy has become nonexistent in many health care institutions, for people and pets alike, so come on ladies put a smile on and be polite. You are, after all, working in customer service. read more

I recently took my dog to Clocktower Animal Hospital and I couldn't be more pleased with the care he received. From the moment we walked in, the staff was incredibly welcoming and attentive. The facility was clean and well-organized, which immediately put my mind at ease. The veterinarians were not only knowledgeable but also took the time to explain every step of the examination and treatment process. During our visit, my dog received excellent care, and I could tell that the staff truly loves animals. They made sure he was comfortable and calm throughout the entire visit, which made a big difference for both of us. Thank you, Clocktower Animal, for taking such great care of my dog! read more

Clocktower Animal Hospital has done so much for my dogs Jojo and because of that we now have our other two dog with them. I am so pleased with all the workers there. From the front desk to the Techs to the Doctors. They care for the animals and you can see it. They know what to do and how to explain things to the owners. Their advise and their medical knowledge makes us all feel good knowing our dogs are in good hands. It helps us to understand what steps to take and how to keep our pets healthy. I recommend them to all pet owners and who care for the health of their pets. Take them to Clocktower Animal Hospital and receive the peace you need. read more

We have been going to Clocktower for several years and have always been happy with the competent and caring doctors and staff. Recently we had to take our dog in for an emergency visit and were just blown away by everything-- from the receptionist gathering the important details over the phone so the doctor and staff could be prepared, to the nurse who met us at the front door and carried him back to the treatment room, to the doctor who knew exactly what to do and communicated with us throughout the entire process. Thank you Clocktower for saving our dog's life and understanding how much our pets mean to us. read more

We had this vet recommended to us by HART, the organization where we adopted our dog. Now we recommend them to any pet owner we know! The level of care is fantastic no matter which vet or tech you see. They also call to check up on your pet after your visit, which is a really nice touch. You can tell every employee really cares about you and your pet, and they are always honest but also conservative about what procedures need to be done. I've found the prices to be reasonable as well and they also offer a pet health savings plan. These guys ate fantastic! read more

We went to Clocktower for a second opinion, and were blown away with them that after years at another vet, we have never looked back. Clocktower far exceeds any other animal hospital, and Dr. Caskaddan and his staff are incredibly caring, knowledgeable, and possess state of the art technology at their disposal for challenging medical needs that your pet may have. I cannot say enough good things to do them justice, but do not hesitate to bring your animals here. It is rare to find this high level of compassion and integrity with excellent vet care. read more

I bring my two cats to Clocktower and have for the past 5 years. The vets and staff are wonderful, so kind and knowledgeable and experienced. They explain everything really well and help me understand what's going on when one of my cats is unwell. I love that they have evening and weekend hours and a doctor on-call when the hospital is closed. Luckily I have never had to use that service, but it's nice to know it is there if we ever need it. My kitties are my babies and I wouldn't trust their medical care to anyone or anyplace else. read more

I recently brought my chihuahua for a routine check up and to set up an appt. for teeth cleaning. I have been to many vets over the years in California, Indiana and now here in Virgina. This place made me and my dog feel comfortable from the minute we walked in the door. They are friendly and courteous. Dr. Diane Panopoulos and her assistant treated Gus like their own. A week later I took Gus back for teeth cleaning and received the same great treatment. They followed up the next day, checking on Gus. I highly recommend this Hospital. read more

This is the best animal hospital. The staff is professional and courteous. I had a dog who was diagnosed with cancer (June 2008) and started taking her here soon after. Dr. Colvin explained to me all my options so that I could make an informed decision in regards to her treatment and was really concerned about her health. He regularly checked up on her and promptly returned all my calls. I think the quality of her life was better because of them (RIP 7/6/08). They really love what they do. I would recommend them to anyone. read more
