I work with you on a personal level to determine the best solutions for your unique needs, then leverage my seasoned expertise to achieve the best possible results.

Relationships
I am your trusted partner in success. I offer Strategic ProActive Tax Planning Services with a  holistic view to your tax situation. My approach is comforting in that we first must be a “match” for each other on this journey. We will work together in implementing your customized ProActive Tax Plan, and on a consultative basis year round to maintain compliance with the changing tax environment as your business grows.

Relief
I do not take a transactional approach, so you will not just see me at tax time, when it is often too late to make changes. I am not your “average tax lady” but a trusted advisor year-round.


Guadalupe Barraza, CPA CTS

Hello Friend,
I am a licensed Certified Public Accountant in the state of Texas (TSBPA) and a Certified Tax Strategist (CTS), member American Institute of Certified Tax Planners (AICTP). I earned a Bachelor of Science in Accounting Control Systems from the University of North Texas and a Master of Science in Accounting and Information Management from The University of Texas at Dallas.

I began my professional accounting career in Corporate America, where I worked in both domestic and international corporate settings and in multiple industries.

My passion however has always been in helping entrepreneurs and business owners like you succeed. I became a Certified Tax Strategist (CTS) so that I could proactively help my clients year-round, versus reactively at tax time. I am not your typical “tax lady”, but the tax advisor you want in your corner! I use advanced tax reducing strategies and am trained to scour the tax code for every credit, deduction, and opportunity so that you can rest assured that you are paying the least amount of tax legally possible.

As a daughter of an entrepreneurial immigrant mother, I saw the sweat, tears, and sleepless nights that went into taking an idea from dream to reality. I understand that sometimes cultural differences, language barriers, and even environmental circumstances can feel like impossible roadblocks to overcome for some business owners. You have the passion but lack the knowledge in areas unfamiliar, such as proactive tax planning, leading to thousands and in some cases millions of dollars in overpayments to the IRS. I help bridge that gap!

So, whether you are thinking of starting a business or have been in operation for some time, contact me today for your free tax analysis. I want to help you save as much of your hard-earned money as possible! There is no cost or obligation other than the money you are overpaying the IRS!

headshot for Sheila Gladchenko, professional bookkeeperHello, I’m Sheila Gladchenko, the founder of GZB Services, LLC, specializing in bookkeeping services. As a degreed accountant working toward Enrolled Agent certification, I bring both expertise and a passion for financial clarity to businesses. I earned my Bachelor of Science in International Business from the University of Phoenix, where I had the honor of delivering the commencement speech for my graduating class.

 
My career spans Corporate America, beginning in Healthcare IT before expanding into manufacturing and the ever-evolving Big Tech sector. I have worked alongside diverse teams to navigate complex financial and operational challenges across various industries, both domestically and internationally.
 
As a first-generation American, born to immigrant parents who overcame unimaginable hardship, I’ve always been driven to support others in their pursuit of the American dream—especially small business owners. My parents built a business that sustained our family, but due to their limited financial literacy and reliance on an untrustworthy CPA firm, they faced devastating IRS penalties. Watching that hardship unfold, I made it my mission to ensure no other business or family experiences financial distress due to poor accounting practices.
 
At GZB Services, we go beyond number-crunching—we provide clarity, structure, and strategic financial organization. Whether you need assistance cleaning up your books or finding a long-term bookkeeping partner, GZB Services is here to deliver tailored solutions with professionalism and integrity.
