Attorney Information
Overview
Attorney Waltenberger hails from Racine, Wisconsin, and is a proud alumnus of William Horlick High School. He furthered his education at Marquette University, graduating with a Bachelor's Degree in Spanish and an Elementary Education Teaching Certification. During his time at Marquette, he immersed himself in the Spanish language and Mexican culture during a summer abroad in Xalapa, Veracruz. There, he embraced the local culture, including daily visits to the Tortilleria with his host father, Raul, to purchase fresh tortillas.
Seeking a new challenge, Attorney Waltenberger enrolled at Temple University Beasley School of Law in Philadelphia, Pennsylvania, known for its top-ranked Trial Advocacy program. He earned the Barrister's Award for outstanding performance in Trial Advocacy and interned at the Philadelphia District Attorney's Office, gaining valuable trial experience. His interest in travel and diversity led him to study abroad at Temple's Rome, Italy Campus.
After graduating, Attorney Waltenberger returned to the Midwest to be closer to his family, settling in Milwaukee. Over the past 20 years, he has dedicated himself to representing personal injury victims in complex cases, earning recognition as a Wisconsin Super Lawyer Rising Star and a member of The National Trial Lawyers Top 40 Under 40 for Wisconsin. He is deeply committed to his clients, ensuring they understand their cases and legal rights, whether their case settles or goes to trial.
Attorney Waltenberger is a staunch advocate for the Hispanic community, providing legal services in Spanish and ensuring they are respected and protected throughout the legal process. He believes in giving back to his community and enjoys spending time with his family, including their Beagle, Walter, and supporting Wisconsin sports teams. Attorney Waltenberger is dedicated to making Milwaukee a more inclusive and vibrant community for all.
