Quentin Gardiner
CPA, CA, CEO, Founding Partner
Quentin is a big man with a big heart. He has a soft spot for entrepreneurs, and he loves it when his clients remark ‘you aren’t a typical accountant’. He is relentlessly focused on helping his clients achieve their goals. When he is not in the office (which is rare), you can find him spending time with his kids, playing golf (poorly he says), or traveling to see Dave Matthews Band. Quentin has over 20 years experience in public practice with the hairline to prove it. He has honed is ability to keep an eye on the forest and not the weeds, and keeps his clients’ best interests in mind in everything he does. Pro Tip: If you’re looking to get on his good side, his weaknesses are scotch and cigars.
Shawn Tully
CPA, CA, Founding and Managing Partner
A frustrated Oilers fan waiting for the next big season! Shawn has a strong background providing accounting, tax and business advisory services to a wide range of businesses, individuals and organizations. Meetings with Shawn will leave you with a feeling of comprehension as he wants to make sure you understand what is being presented. He creates an environment where you feel comfortable asking the questions you need to. Currently, he is on the Board of Directors for Crimestoppers Association of Edmonton & Northern Alberta as President. Crimestoppers is an organization that he has been involved with for over 5 years.
Along with being a hopeful Oilers fan and avid music lover, Shawn is a devoted husband to his wife Leah, and father to two beautiful girls, Keira & Ella. Pro tip: If you want to get on his good side, play some Dave Matthews Band & show up with Reese’s Peanut Butter Cups.
Tyson Breitkreutz
CPA, CA, Partner, Tax
Tyson’s unique sense of humour and style set this man apart from all the rest. He obtained his Bachelor of Commerce with Distinction from the University of Alberta in 2007, his CA designation in 2010 and joined our firm in 2012. Tyson is constantly on the quest for further education, spending his lunch breaks studying to upgrade his skill-set. He is actively involved in the Canada Revenue Agency Community Volunteer Income Tax Program and provides tax preparation services to low income senior citizens and new Canadian residents. We’re not sure where he finds the energy for these commitments as well as his dedication to his young family, classy bow-tie collection and his passion for the fight against Multiple Sclerosis.
Alex Lee
CPA, CA, Director of Integrated Financial Services
Alex Lee, CPA, CA is the Director of Integrated Financial Services at HGA CPA, where he partners with leadership teams to turn financial information into confident, forward-looking decisions. He approaches the CFO role as it should be practiced: not simply explaining what happened, but helping organizations decide what to do next by connecting financial reality to operations and strategy.
Alex holds a Bachelor of Commerce from the University of Alberta and began his career articling with a respected local accounting firm before earning his Chartered Accountant designation in 2010. He brings a distinct perspective to small and medium-sized businesses, regulatory organizations, and not-for-profit entities, particularly those navigating complexity, growth, or change.
Alex brings a thoughtful perspective to the role of analysis within organizations. While strong data retrieval is essential, he places greater emphasis on interpretation—asking the right questions and translating financial information into practical insight leaders can rely on.
Proudly based in Edmonton, Alex values the city and its community and is an unapologetic Edmonton Oilers fan. Outside of work, he is a proud father of two young children and values time spent with his family. He values clear thinking, honest dialogue, and practical solutions that support better decisions.

You didn’t start your business to sort receipts, stress over deadlines, or hope your accountant and lawyer eventually end up on the same page.
You deserve financial guidance that’s proactive, coordinated, and built around how real owners make decisions.
At HGA CPA, we go beyond traditional accounting. We act as the financial co-pilot for Edmonton’s owner-managed companies—helping you reduce tax, stay financially organized, and make smarter decisions with confidence.
1. Proactive Tax Planning That Actually Saves You Money
Year-round tax strategy—not last-minute filings.
Our CPAs work directly with HGA Law LLP and HGA Wealth to design corporate structures, compensation strategies, and planning models that minimize tax today and over the long term.
2. Clean, Accurate, Always-Current Financials
Cloud bookkeeping, real-time dashboards, and clear monthly reporting.
No surprises. No scrambling. Just reliable numbers that help you understand exactly where your business stands.
3. Advisory Insight That Helps You Grow
Forecasting, pricing analysis, cash flow planning, acquisition modeling, and succession strategy.
Your CPA should help you build wealth—not just report what happened.
Because we operate inside the HGA Group ecosystem, your accountant collaborates daily with:
- HGA Law LLP on tax-efficient reorganizations and contracts
- HGA Wealth on compensation, retirement, and long-term planning
- HGA People on bonus structures and payroll strategy
- HGA Employee Benefits on tax-advantaged benefits planning
This is the advantage of having your accounting team integrated with the rest of your advisory team—not spread across separate firms
- Thousands (often tens of thousands) saved annually in tax
- Faster, more confident financial decisions
- Better alignment between accounting, legal, HR, and wealth strategies
- More money in your pocket—and more clarity in your business
