    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 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
