What I'm looking for

I’m looking for a role managing accounts receivable operations, improving receivables performance, and supervising a cross-functional billing team to support accurate financial reporting.

At Greenwich House, I led accounts receivable and revenue operations, overseeing a team of A/R specialists and financial activity across multiple payment platforms. I reduced overdue balances by 20% through structured follow-up workflows and helped reduce patient A/R by 30% by strengthening collection policies.

I owned revenue reconciliation and month-end close for $1M–$2M in monthly activity. By aligning ACH posting dates with bank statements and general ledger activity, I reduced discrepancies by 25% and supported accurate financial reporting.

Earlier at Greenwich House, I worked as a Revenue Cycle Analyst, analyzing claims and partnering with clinical staff to reduce coding-related denials by 60%. At Mount Sinai, I worked as a Billing Specialist, resolving patient billing issues and mentoring less experienced billing staff.
