Albion Street Denver Practice
Professional Bookkeeping & Tax Assistants runs from a Suite 250 office at 865 Albion Street in the Denver 80220 zip and works with small-business owners on books, payroll, and tax filing. Amy Iannone is named on the shop’s About page as the founder, with 25 plus years of office management, payroll, and bookkeeping work behind the practice plus seven years of tax preparation experience. The firm sits inside Denver city limits rather than in a metro suburb, which suits owners who want a Denver-proper bookkeeping shop.
Top 10 ProAdvisor Listing
The firm holds Advanced QuickBooks Online ProAdvisor status, which Intuit issues to ProAdvisors who pass the upper-tier QuickBooks Online certification exam. Amy Iannone is also listed as a Top 10 QuickBooks ProAdvisor in Denver on the Intuit Find-a-ProAdvisor directory, a public ranking that reflects active client engagements and certification activity. That status fits owners who want a shop with both QuickBooks Online depth and a public Intuit credential.
Bookkeeping Plus Tax Bundle
Service categories pair small-business bookkeeping and QuickBooks Online cleanup with payroll processing, federal and state tax return preparation, tax planning, and part-time CFO work. The cash flow management and internal controls lines fit owners who have outgrown a basic bookkeeping setup but still need a single shop. Construction is named on the practice’s own site as a sector served, and the practice positions general small-business work as the core book of business.
Virtual Bookkeeper Reach
Because Amy Iannone is set up as a virtual bookkeeping, payroll, and tax professional through SheLeads networking groups, the firm pairs its physical Denver office with remote service across the country. Owners who keep books in QuickBooks Online can hand off cleanup, monthly close, and tax filing without needing in-person meetings, while Denver clients can still drop into the Albion Street office for face-to-face work.

Denver West Parkway Office
Golden Bookkeeping Services works from a Suite 100 office at 14143 Denver West Parkway in Golden, the Jefferson County city that sits along the I-70 corridor in the western Denver metro. Denisha Marino is the founder of record per the company’s About page and her LinkedIn profile, and the practice has held its 2005 start date through 21 years of small-business work. The Denver West office park puts the shop in driving range of clients across Lakewood, Wheat Ridge, Arvada, and downtown Denver.
Multi-Track ProAdvisor Status
The firm holds four QuickBooks ProAdvisor certifications stacked together: Online, Desktop, Advanced Desktop, and Enterprise Solutions. That stack matters for clients who run on legacy QuickBooks Desktop or Enterprise files, since many bookkeepers now hold only the Online certification. The practice also lists membership in the National Association of Tax Professionals and the American Institute of Professional Bookkeepers, alongside the Accountex and QBExpress accounting communities.
Bookkeeping with Outsourced Controller Track
Service categories include monthly bookkeeping, QuickBooks consulting and training, payroll, and outsourced CFO and controller work. The controller and CFO line fits small businesses that have outgrown basic bookkeeping but are not yet at the size to bring an in-house controller on payroll. Cleanup work, file conversions, and small-business accounting are also named on the services page.
Cross-Industry Background
Denisha Marino’s published background covers banking, financial services, and the oil and gas sector before she founded the practice. That track record sits behind a current client base that the firm describes as small-business owners across general sectors, rather than a single industry niche. Owners in regulated or technical sectors often pick the company for that earlier experience.
3. Capital Bookkeeping
- Address: 9800 Mount Pyramid Court, Suite 400, Englewood, CO 80112
- Phone: (720) 200-5025
- Founder / Owner: Sheila Kaiser (Owner)
- Operating Since: 2004 (22 years)
- Credentials: Senior QuickBooks ProAdvisor; Inc. registered in Colorado as Capital Bookkeeping, Inc.; second staff QuickBooks ProAdvisor on the team
- Service area: Denver metro market from a south-suburb office in Englewood
- Industries served: Small businesses across general sectors, with named work in technology companies and medical clinics
- Website: capitalbookkeeping.com
Englewood Meridian Office
Capital Bookkeeping runs from a Suite 400 office at 9800 Mount Pyramid Court in Englewood, inside the Meridian Corporate Center 1 building near the I-25 and E-470 interchange in the south Denver metro. Sheila Kaiser is the owner of record per LinkedIn, the RocketReach business profile, and the Datanyze company page, and the shop has held the same Inc. structure since 2004. The Englewood office puts the practice in driving range of Centennial, Greenwood Village, Lone Tree, and Highlands Ranch clients on top of central Denver.
Senior ProAdvisor Pairing
Sheila Kaiser is listed as a Senior QuickBooks ProAdvisor on the firm’s Our Team page, with Lora Jackson listed as a second QuickBooks ProAdvisor on staff. The Senior tier is an Intuit ProAdvisor designation issued for sustained QuickBooks work and active recertification. The two-ProAdvisor setup matters for clients who want bench depth past a single owner shop while still working with a small-firm bookkeeping practice.
Full-Service Bookkeeping Track
Service categories include full-service monthly bookkeeping, QuickBooks setup and implementation, periodic file reviews, project consulting, financial reporting, and tax preparation coordination with outside CPAs. The periodic file review line fits owners who do their own daily bookkeeping in QuickBooks but want a quarterly or annual check on accuracy. Project consulting fits one-off work like file conversions or cleanup of multi-year backlogs.
Pre-Founding Bookkeeping Track
Sheila Kaiser’s published background includes seven years at Qwest in bookkeeping and accounting roles before she took the owner seat at Capital Bookkeeping. That stretch sits behind a current client base that includes named technology companies and medical clinics, and the company positions itself as a general small-business shop without limiting work to a single sector.

- All three firms appear as independent, founder-led, or family-led practices and not as franchised or rolled-up brands such as Bench, Pilot, QuickBooks Live, BELAY, Bookkeeper360, Bookminders, Supporting Strategies, Bookkeeper.com, or 1-800Accountant.
Selection Methodology
This list applies four filters to the Denver market. First, the practice has to be independent, family owned, or founder led rather than part of a national rollup or franchise brand. Second, the firm must show active QuickBooks credentials or a QuickBooks-centered practice, with that focus visible on its own site or on a third-party directory. Third, the company has to have been in business for at least five years, with priority given to firms past the ten-year mark. Fourth, the shop has to position itself as a bookkeeping practice rather than a pure CPA tax-prep shop. Public address and phone data also had to match across at least two independent sources, including the practice’s own site plus a directory record such as LinkedIn, RocketReach, Datanyze, ZoomInfo, LoopNet, SheLeads Group, or Reputable Accountants. National rollup brands such as Bench, Pilot, QuickBooks Live, BELAY, Bookkeeper360, Bookminders, Supporting Strategies, Bookkeeper.com, and 1-800Accountant were excluded by design, since this directory targets locally owned shops in the Denver market.
Frequently Asked Questions
Do these firms serve clients outside Denver proper?
Yes. Professional Bookkeeping & Tax Assistants works from an Albion Street office inside Denver city limits and pairs that location with virtual bookkeeping, payroll, and tax service across the United States. Golden Bookkeeping Services works from a Denver West Parkway office in Golden and serves clients across Lakewood, Wheat Ridge, Arvada, central Denver, and remote clients beyond Colorado. Capital Bookkeeping works from a Mount Pyramid Court office in Englewood inside the Meridian Corporate Center and serves the south Denver metro plus central Denver clients.
Are these firms CPA practices or bookkeeping practices?
All three position themselves as bookkeeping and QuickBooks practices rather than as CPA audit shops. Professional Bookkeeping & Tax Assistants pairs Advanced QuickBooks Online ProAdvisor work with payroll and federal and state tax return preparation under an Annual Filing Season Program credential. Golden Bookkeeping Services holds four QuickBooks ProAdvisor certifications and pairs bookkeeping with outsourced controller and CFO work. Capital Bookkeeping pairs full-service bookkeeping with tax preparation coordination through outside CPAs. Owners who need formal CPA audit or attest work would still need to retain a licensed CPA firm separately.

Yes. Professional Bookkeeping & Tax Assistants is set up as a virtual practice with national reach on top of its Denver office. Golden Bookkeeping Services pairs its Golden office with remote support that extends past Colorado for clients who prefer cloud-based QuickBooks files. Capital Bookkeeping works from an Englewood office and supports both on-site and remote engagements through QuickBooks Online and QuickBooks Desktop with hosted access, which suits owners who run multiple locations or travel often.
How long have these firms been operating?
Golden Bookkeeping Services was founded in 2005 (21 years). Capital Bookkeeping has held the same Inc. structure since 2004 (22 years) under owner Sheila Kaiser. Professional Bookkeeping & Tax Assistants was started in 2017 (9 years) by Amy Iannone. Each firm sits past the five-year minimum tenure threshold this directory applies, and each has stayed independent across its full window.
