Press releases are traditionally written as if unbiased news, not in first person (If thine “I” offends thee, pluck it out). I have found the following useful when writing a press release in which I need to quote myself.
Write what you want to say in the release, then before finalizing it, write those exact words in a blog post. Of course you’ll need to use your name, probably spelled the same, in both of them. Just remember to publish the blog post before publishing the press release. If you can include the title of the post in references at the bottom of the release, it can show the news publisher it is valid and safe to publish.
