About Us

ZATO's core business goal is simple: to provide our clients with excellent Paid Search advertising in a way that supports our own employee personality, growth, and health.

This doesn’t mean we don’t understand hard work, it does mean we won’t sacrifice your account quality, or our employee satisfaction on the altar of agency growth.

We love to develop long-term relationships with clients that are mutually beneficial and we build these relationships through time, results, and positive intentional communication.

(Did we mention we don't do long-term PPC contracts?)

He has been named one of the Top 25 Most Influential PPCers in the world by PPC Hero 5 years in a row (2016-2020), has written articles for many industry publications (including Shopify, Moz, PPC Hero, Search Engine Land, and Microsoft), and is a frequent guest on digital marketing podcasts and webinars.

Kirk currently resides in Billings, MT with his wife, six children, books, Trek Bikes, Taylor guitar, and little sleep.

Kirk is an avid "discusser of marketing things" on Twitter, as well as an avid conference speaker, having traveled around the world to talk about Paid Search (especially Shopping Ads).  Kirk has booked speaking engagements in London, Dublin, Sydney, Milan, NYC, Dallas, OKC, Milwaukee, and more and has been recognized through reviews as one of the Top 10 conference presentations on more than one occasion.

You can connect with Kirk on Twitter, and Linkedin, or follow his marketing song parodies on TikTok.

Sarah Vlietstra

Paid Search Strategist

Sarah started her career in digital marketing by working as a contractor at Google.

Over the last 6 years, she has worked with thousands of Google Ads accounts, gathering specific insight into industry benchmarks, trends and data. Because of her time representing Google, she excels at implementing Google Ads best practices in ZATO clients to maximize machine learning applied intelligently through a human framework.

Sarah is also passionate about educating others regarding Paid Search products, and actually taught the existing ZATO team about a specific product on her first day ever working at ZATO!

Sarah lives in Tempe, Arizona with her husband, two sons, dog, and Russian tortoise. She enjoys spending time with her family, getting house projects checked off the list, and traveling throughout Arizona and to her home state of Michigan.

Diana Talhelm

Paid Search Strategist

Diana moved to the United States in 2004 from Russia, while pursuing a career in sales. In 2013, she became a contractor representing Google to agencies where she worked closely with a variety of companies and agencies, helping them achieve their goals, providing strategic advice, assisting with troubleshooting, and educating them about the Google Ads platform.

Diana has an insatiable curiosity regarding Google Ads algorithms, and does all she can to figure out "why" things are the way they are in her client accounts, not simply "what" is happening.

Diana lives in Chandler, Arizona with her husband, two kids, two dogs, and a cat. She loves nature and enjoys hiking, gardening, biking with her dogs, and horseback riding.

Chris Reeves

Small Budgets Program Director

Chris is tasked with growing and developing the Google Ads for Small Budget program at ZATO. He's passionate about marketing, with 10+ years of sales and management experience and has succeeded in those fields by streamlining operations and making his team and procedures as efficient and productive as possible.

While employed at a local non-profit organization, Chris stumbled across PPC and was instantly enthralled by the possibilities of the digital marketing world. His extensive background and relentless optimism made him a great fit to build ZATO's Small Budget program.

Outside of work, Chris spends his time with his wife and their 2 dogs. He has called Billings home for the past 32 years and he enjoys seeing and playing concerts (that's right... he's in a band), spending time with friends, and hiking around the Montana mountains.
