"Dr. Brooks was incredibly patient and compassionate in caring for our dog with an obstruction. He worked closely with us to avoid surgery through careful monitoring and daily check-ins. He explained every option in detail, helped us weigh what was best for our dog, and made sure we had a clear plan in place heading into the weekend. He even called to check on our dog’s progress, which meant a lot. In my experience, Dr. Brooks went above and beyond what you’d expect from a vet. He’s thorough, trustworthy, and truly cares about his patients. I highly recommend him to anyone looking for exceptional care for their dogs."

"I can’t say enough good things about this vet office and Dr. Brooks! From the moment we walked in, we were treated with genuine care and compassion for both me and my animals. Dr. Brooks is incredibly knowledgeable, kind, and takes the time to explain everything in a way that makes you feel informed and confident. One of the biggest reasons I keep coming back (besides how amazing he is with my animals) is how affordable they are. Vet care can get expensive fast, but this clinic is honest, fair, and never pushes unnecessary treatments. It’s clear they genuinely care about helping not just running up a bill. Dr. Brooks is someone you can trust with your pets’ health. He treats every animal like it’s his own, and that kind of care is rare these days. I’m beyond grateful to have found a vet like him. Highly, highly recommend!"

"We have been going to Lakeside for over 10 years. My cat had a urinary condition which continually incurred high veterinarian emergency bills and required prescription food. What I appreciate most about Dr. Brooks and the staff is that they work with you to create a reasonable care plan at the lowest cost options. We were used to emergency visits with high medical bills, but once we started using Lakeside, we were able to manage his condition and went many years without any additional visits! When we had to eventually put our boy down at 15 years old, it was an extremely comfortable environment where we felt respected and comfortable and they made every effort to get us in for any visits we needed during times that were convenient for us. I even brought my two daughters with me as they wanted to be with him, and they handled everything so gracefully. We now have two guinea pigs and will indefinitely continue our care at lake side!"

"Friendly and helpful staff, the team here always goes above and beyond. You can get medications, supplements and food, plus you can get your dog license here. All in one service with a smile. Medication seems a bit more expensive than it could be, but what can you do about that. If you want the best service for your pet in the area, or even out of the area, and you want someone who truly and honestly cares about your pet and your concerns for their well being and long healthy lives, you absolutely need to come see Dr. Brooks at Lakeside Animal Hospital."

"I've been taking my babies to Dr.Brooks since 2021. The clinic is clean and homey, and the staff are incredibly kind and understanding. Dr.Brooks has treated my dogs and cat for routine treatments and upkeep as well as emergency situations. In every visit we've had he has been very thorough. He clearly communicates every step, And truly has your animals best interests at heart. He doesn't seem to be interested in upcharging you, or giving your animals any unnecessary treatments just to pad your bill. Ive recommend several people to them, and my entire family takes all their animals to him ( that's a totally of 3 cats and 8 dogs over the years). When it comes to that time when you have to say goodbye to your babies, the staff at Lakeside animal hospital creates a safe and peaceful place to do so. I feel confident that anytime I take my babies to this clinic they are receiving top notch care, and whatever issue they are being seen for , will be resolved!"

"What can I even say about Dr. Brooks to give enough credit? He is a compassionate, knowledgeable, honest, thorough and reliable vet for those of us in the area that don't have "normal" pets. To have a trustworthy vet so close that can care for our exotics and reptiles is a big sigh of relief. 5 stars isn't enough. Dr. Brooks deserves 10 stars. So glad to have a vet we can count on."
Kelly Rudowyj
"Dr Brooks is an absolutely fantastic doctor. I refuse to see anybody else! I had another vet years ago who outright lied about my dogs health.Giving me the worst news you can get for your pet. Dr Brooks rechecked my pet confirming it was a gross misdiagnosis. And he has cared for my pets ever since. He really cares for animals and the people that take care of them. I refer anybody with a pet to him. He will NOT lie to you and always will do his absolute best to help you care for your fur babies…"

"Dr Brooks is the best. He helped us with our blind collie’s hot spot the same day we called. Update: Dr. Brooks and his team saw our blind collie again when he suddenly was having trouble getting up on his own. We had a great consultation and changed some meds, and he is improved. Dr. Brooks even followed up twice to check on our collie, once on Friday to make sure we wouldn't have a crisis over a weekend and need to go to an emergency vet. Dr, Brooks and his team are fantastic!"

I trust their advice and experience when things get difficult, and sometimes they do. Pet care is important, l feel they are on my pets and my side when l go there."

"I can’t say enough good things about Lakeside Animal Hospital. Always a great experience with Dr. Brooks and his kind and caring staff! Dr. Brooks is very compassionate and straightforward. He has a big heart and a true passion for his profession - this is evident in every visit. I was really anxious about an enucleation but he was very confident and reassuring that this was the right decision. So grateful to have found such a wonderful vet. Highly recommend!"

"Took my sphinx cat in with an hour notice, and was greeted by a warm and professional staff, and an excellent physician. Everyone had outstanding bedside manner. A diagnosis was made, and I was in and out in less than 30 minutes. Highly recommended."

"Dr. Brooks has been our dog Kodi’s Vet his entire life to date. Kodi absolutely adores his vet, and runs straight to the car every time I say, “we’re going to see Dr. Brooks.” I give Lakeside Animal Hospital 5 stars because Kodi has had everything from routine visits to surgical procedures there and there’s not been any issues. Dr. Brooks knows that Kodi is family and treats him as such."
