Welcome to Lakeside Animal Hospital. Our expertise and passion for veterinary medicine and the animals we serve is equaled only by our devotion to you, our pet owners.

When you’re searching for an animal hospital near you, consider us. We’re located just north of Bayshore Towne Center and right off of Highway 43. Our pet hospital has been here over 80  years, allowing us to serve generation after generation of your family’s pets. We’re proud to have four full-time veterinarians on staff, providing a depth and breadth of knowledge and experience you won’t find anywhere else. If you’re new to the area or searching for a new veterinarian, you might wonder why you’d choose Lakeside Animal Hospital. Here’s what generations of our clients have told us:

We’re honest. You can expect appropriate recommendations for your pet based on the circumstance and best veterinary practice, never based on how many tests or procedures we can accumulate from your visit.

We’re intelligent. We are committed to continuing education and accreditation, which ensures that we remain above average, providing you and your pet with the most up-to-date practices and the highest quality care available.

We’re caring. We wouldn’t be here if we didn’t really care. Each pet-owning staff member sees this not as a “job” but as a “mission.” Our compassion and empathy extend not only to our animal patients, but to you, our human clients as well.

When it’s time for your pet’s annual wellness exam or you are concerned by a change in your pet’s behavior, give us a call. We’re your local resource for all of your pet’s needs. We’re about pets and their people.

We are happy to offer a number of resources that enable you to learn about how to take better care of your pets. Please feel free to browse our site, particularly the informational articles. The best veterinary care for animals is ongoing nutrition and problem prevention, so becoming knowledgeable about preventative pet care is essential to the ongoing success of your animal’s health. If you have any questions, call 414-962-8040 or email us and we'll promptly get back to you. You can also check out our practice brochure. Our hospital is very easy to get to and you can find directions on our Contact Us page! We also welcome you to subscribe to our newsletter, which is created especially for Lakeside's pet owners.

    Jeffrey Kowitz

    Dr. Kowitz graduated from the University of Wisconsin in 1990 and joined the Lakeside staff in 1995. He brings amazing experience to his practice, and clients really like working with him for his compassion and his ability to talk medicine in ways that are easily understood. He is our ultrasound guru and is very willing to explain and teach his colleagues about ultrasound. In his words “The camaraderie and cooperation of the staff is wonderful”.

    When not working he enjoys singing, helping coach his son Matthew’s baseball team and fishing. He and his wife, Melissa, have two children Matthew and Hope. Their household also includes four furry family members – two cats, Baxter and Phinneas, and two dogs, Shamus and Daphne. The Kowitz family enjoys all the different types of entertainment Milwaukee offers – sports, music and theater as well as the culture diversity found in the area.

    Judy Martinez

    Dr. Martinez graduated from the University of Wisconsin in 1995 and has spent the majority of her career her at Lakeside, joining the hospital medical staff in 2001. She enjoys feline and canine internal medicine, and is a well-loved vet at Lakeside. Dr. Martinez loves the staff and her clients. Many, she has seen for years and watched their furry family members grow. She also enjoys developing new client and pet relationships.

    Dr. Martinez and her family stay busy in spring, summer, and fall going to Milwaukee’s many festivals, the Brewers games, exploring downtown and the lakefront – “there is so much here.” She and her husband, Chris, have two daughters, Madi and Rosa “they rock.” Driving them to school, to and from sporting events and camping during the summer means a highly active schedule for the family. Also sharing their home are three awesome cats Daisy, Enrique and Madame Butterfly, who came into Lakeside in 2010 as four week old kittens that were headed to the humane society. Not one to stand back and let that happen, she brought them home instead – one of her happiest days.

    Favorite book: I need to get back to reading….

    Favorite movie: Willy Wonka & the Chocolate Factory – brings up great memories from childhood.

    If you could have one superpower what would you choose? I would love the ability to speak to the scared, anxious dog or cat and let them know we are trying to help them, not hurt them.

    Favorite quote:  Wag more, bark less.

    When playing rock, paper, scissors which one is your go to?  Really?!  Probably paper.

    Robert Poetzel

    Dr. Poetzel graduated from the University of Wisconsin School of Veterinary Medicine in 1990 and joined the Lakeside staff in 2005. He enjoys all types of surgery, and has repaired many cruciate tears (anterior cruciate ligament) for our canine patients. He also has a soft spot for new puppy and kitten exams. Practicing at Lakeside is great because “It hardly seems like work when you are surrounded by hard working, friendly, enthusiastic coworkers.” He has a sharp and dry wit which is appreciated by the Lakeside staff and keeps us on our toes.

    Dr. Poetzel likes Milwaukee because of “how ridiculously friendly people here are and it takes me leaving the area to realize that.” When not at work, he enjoys watching his daughter play fast pitch softball, or fishing with his wife, son, and daughter. The Poetzel family has two Labrador retrievers, a parakeet, guinea pig, and a snake.

    Favorite book: Lord of the Rings trilogy

    Favorite movie: The Lego Movie

Additionally she has an interest in ultrasound.  Dr. Dallwig welcomes the diversity of cases found at Lakeside, as well as the great support staff and overall sense of camaraderie.

    When not working Dr. Dallwig keeps very busy – she loves to scuba dive, hike, snowshoe, travel – pretty much anything outdoors and adventurous. Like many of us, she loves the close proximity to Lake Michigan and the numerous state parks Wisconsin has to offer. She lives with three cats – Magnum, Jackson and Mya (the diva!) and a bearded dragon named Oscar.

    Favorite book: Likes easy to read fiction

    Favorite movie: Fast & Furious series

    If you could have one superpower what would you choose? Only one? I would like the ability to speak/understand all languages, communication with animals and it would be really nice to eat whatever I want without calories!!!

    Favorite quote:  Life should not be a journey to the grave with the intention of arriving safely in a pretty & well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming “Wow! What a Ride!” – Hunter Thompson

    When playing rock, paper, scissors which one is your go to?  Depends on my mood.
