Colorado’s top tax collector is moving on, but it’s not clear where. The governor’s office announced this week that Barbara Brohl is stepping down in August as executive director for the Colorado Department of Revenue.

Six years on the job, Brohl oversaw the Department of Revenue’s taxation division, the Division of Motor Vehicles, the state lottery, horse racing enforcement, automobile Dealers, gaming, liquor and tobacco, as well as the recreational and medical marijuana.

“Barb has provided strong leadership to the Department of Revenue,” Gov. John Hickenlooper said in a statement. “We will miss her steadfast and guiding hand, but wish her much success in the future.”

Questions to the governor’s office and the Department of Revenue about why Brohl is stepping down and what she’s doing next didn’t get a clear answer, but it didn’t sound like anybody has hard feelings.

In the governor’s press release, Brohl called her work as a tax collector “the opportunity of a lifetime and absolutely the best job I have ever had.”

“I have had the luck, the pleasure and the honor of leading a phenomenal team through it all, without whom none of this would have been possible. We have been able to accomplish so much in the past six years and I am very proud of where this department is today.”

The governor’s office said Brohl would still be on the job until August, when Hickenlooper will have only 16 more months left in office himslf.

I asked the Department of Revenue for more details and got a lengthier statement from Brohl:

“In the past 6 years I have had the pleasure of leading the Department of Revenue, I have been involved in some of the most interesting subjects – I oversaw the implementation of new systems in Tax, Lottery, and DMV. We have improved processes, added new functionality, and elevated customer service as a core value,” she said.

“In addition, I was a named party in a U.S. Supreme Court case – DMA v. Brohl; the DMV implemented SB13-251 driver licenses and IDs for residents who cannot demonstrate lawful presence; and the Liquor Enforcement Division has begun implementation of SB16-197 – the most comprehensive liquor legislation since prohibition,” Brohl continued.

“Finally, I was responsible for the rollout of the first-in-the-world commercial regulatory system for recreational marijuana. I co-chaired the Governor’s A64 Task Force and helped to set the policy, direction, and strategy for recreational marijuana in the state. As a result, I have consulted with governments all over the country and the world as they evaluate their own drug policy, and was an invited panelist at the United Nations in Vienna.

“I love this Department so it is with mixed emotions that I have decided it is time for me to see what is next for me. I am very proud of what I have accomplished at the Department and I’m looking forward to what the universe will involve me in next!”
