Google reviewers rate the firm 4.8 out of 5 stars based on 76 reviews, frequently citing efficiency, thorough tax preparation, and reasonable pricing for services like S-Corp filings and payroll. Clients often note that the accountant provides clear advice and handles complex situations with patience, though the owner replied to only 4% of feedback. A recurring criticism in low-star reviews involves poor communication and missed deadlines, with one client alleging an unsubmitted return caused significant penalties and another claiming a missing document triggered an audit without adequate follow-up.
