Hi, I’m Katrina L. Martin,

I have a passion for helping small businesses go from concept to market, I consult with business owners and entrepreneurs looking to start or expand tax preparation firms. Throughout my career, I have amassed specialized knowledge and experience in all aspects of marketing, business origination and tax preparation.

When advising clients, I draw on my accomplishments as a business owner and operator. I am the founder and CEO of Wow Tax Service (, a veteran-owned Michigan based tax preparation company. This business started in my basement in 2003 and it has grown to support a large client base.

I am most proud that my clients regard me as a trusted advisor, mentor and confidant. I understand the ups and downs that come with running a seasonal business. And have developed proven strategies for supplementing income during slow seasons and smart ways to eliminate slow seasons all together. 

In addition to my work as a consultant, I welcome new opportunities to connect with and help people hit the ground running with their new business ventures!
