Dr. Neela Lalani

Dr. Neela Lalani began her educational career at Emory University in Atlanta, where she earned her Bachelor of Arts Degree. After discovering her true passion for the science and art of dentistry, Dr. Lalani went on to achieve her Doctorate of Dental Medicine from the University of Louisville School of Dentistry (Go Cards!). Upon graduating, Dr. Lalani attended an Advanced Education in General Dentistry Residency Program at the Milwaukee Veteran’s Affairs Medical Center, where she compassionately cared for those who have served our nation. During her residency, she realized her strong interest in prosthodontics, the practice of making prosthetics, such as partial dentures, full dentures, bridges, and crowns. Dr. Lalani enjoys granting her patients the ability to eat and the confidence to smile again and has had great success in treating even the most difficult cases. In addition to hard work and passion, she attributes her professional success to her lifelong advocate and one of the most resilient men she knows – her father. 

When Dr. Lalani is not treating patients or studying cases and literature, she enjoys traveling, cheering for the Milwaukee Bucks and Louisville Cardinals, and spending time with her husband, Imran. She is a fun aunt to three nieces, a nephew, and a loving dog-mom to her puppy, Hotchner.

Dr. Cassie Hammen

Dr. Cassie Hammen’s DDS interest in healthcare started at a young age, but her excitement for dentistry was fostered after shadowing her hometown dentist. Connecting with patients, providing a service, and navigating an ever changing career field ignited a passion for Dr. Cassie.

After graduating from UW Oshkosh with a degree in biology, Dr. Cassie received her doctorate in dentistry from Marquette University, graduating with summa cum laude honors. Since joining the field, her favorite aspects of dentistry are helping patients get out of pain and being confident in their smiles.
