I have created and led marketing campaigns for over 150 books over the last 15 years and have experience in author branding too. I am well-respected and sought after in the publishing industry.

Projects

Scary Close by Donald Miller

I created and led the entire book marketing campaign. The ticketed launch event I organized resulted in the book hitting #1 of ALL books on Amazon. First week sales were 14k and we hit the New York Times bestsellers list. Due to the amount of positive reviews I acquired from the launch team I led, the book was a Goodreads Awards finalist.

Girl, Stop Apologizing

I created and led this marketing campaign in full. The preorder offer, social strategy, ad strategy, 800 person micro influencer campaign, and email marketing strategy I created resulted in a preorder record for Harper Collins of over 200k books. During launch week, the book was in the top five of all books on Amazon. #1 New York Times Bestseller out of the gate. Spent over a year on the NYT list. Over 17k Amazon ratings.

Girl, Wash Your Face

I created and executed the full marketing plan. I helped Rachel Hollis build her brand and following while creating and implementing a strategic marketing plan to achieve New York Times bestseller status. #1 NYT bestseller. Spent over a year on the list. Sold over 1 million books in year one. Over 41k Amazon ratings, many of which were the result of the launch team I led and the online book club I executed. The online book club with free downloadable grew the author's email list from 30k to 100k subscribers.

Undistracted by Bob Goff

Created and led the marketing and PR campaign that landed the book on the New York Times list on launch week. The social strategy, email marketing campaign, and online event I created resulted in over 15k books sold in week one. Over 1,800 Amazon ratings many of which are attributed to the bookstagrammer tour I oversaw and the launch team I ran.

Stephanie is an extraordinary professional, she is proactive, she is very resourceful, her work has a very high quality. In this collaboration with Facebook Ads we had outstanding results in terms of clicks. What we were not able to achieve were sales, but I know the topic of my book is very hard...
