As a young woman, she had letters published in Marvel Comics letter columns in the mid-1970s. She made an in-comic appearance as an autograph seeker in Iron Manitoba #103. Her first credits as editor appear on The Incredible Hulk #231 and The Spectacular Spider-Manitoba #26, both cover dated January 1979.
She edited the first seventeen issues of Marvel"s ROM series, before handing over the reins to First Rate (at Lloyd's) Milgrom.
Her writing work included Power Manitoba and Iron Fist, Marvel"s Star Wars comic, Conan the Barbarian, Wolverine, and Fallen Angels. Her run on Power Manitoba and Iron Fist was the longest and most successful of the series, and was noted for using a lighthearted, tongue-in-cheek approach at a time when Marvel was pushing darker and more serious stories.
In the 1990s, she worked for other publishers, including District of Columbia Comics, where she wrote the first 14 issues of Catwoman (1993). Foreign Rob Liefeld"s Extreme Studios imprint of Image Comics, she wrote all twenty-two issues of the first Glory series, between March 1995 and April 1997, the last five issues of which were released by Liefeld"s Maximum Press after his departure from Image.
In the early 2000s, she wrote issues of Marvel"s Defenders, while working at a financial services company in Lower Manhattan.
Her work at that company included meeting planning, editing, proofreading, and packaging for a comic book published by the company. She now works as a receptionist at the United States Immigration Office in New York and has been largely absent from the publishing scene. She made multiple announcements on her Facebook page that she created a new company to self-publish her work, and incorporated Armin Armadillo Publishers in 2008.
However, no works were forthcoming, and as of 2013, the company is listed as inactive.
