Johanna is a lawyer and registered Canadian patent and trademark agent with Cassan Maclean. She completed her articles with a national Canadian law firm, then practiced for several years with another intellectual property law boutique before joining US in 2006.

Johanna has a broad academic background; she graduated from McMaster University's Arts & Science program, an exclusive liberal arts program that covers a wide variety of subjects including literature, physics and philosophy. Johanna focused her studies on biochemistry, undertaking a research project on aluminum absorption and its possible connections to Alzheimer's disease.

After obtaining her Bachelor of Arts and Science, she went on to study law at McGill University, where she was awarded the Dean Ira MacKay Prize for outstanding achievement in torts. Johanna's practice covers all aspects of intellectual property law, and she has significant experience in trademark, patent and industrial design prosecution before the Canadian and United States Patent, Design and Trademark Offices. Johanna has particular expertise in biochemical and chemical patents.

Outside of the office, Johanna enjoys an active lifestyle, including cycling, running, and swimming whenever possible. Johanna has a passion for travel, and often combines physical activity with exploration of new destinations, such as Mount Kilimanjaro in Tanzania, and Mount Bromo in Indonesia. Her travels and lifestyle will be more child-focused in the coming years, as she and her husband will soon be welcoming a new addition to the family.
