Westside Billing LLC

Mental health practitioners in Massachusetts spend too much time fighting with insurance companies and not enough time with their clients. Westside Billing LLC is a full-service medical billing company based in Holden, MA, built specifically to take that burden off independent providers and group practices. By outsourcing their billing to a dedicated specialist, practitioners can stop chasing claims and focus on patient care. The core Premium Service Plan covers electronic claim submission, tracking, EOB review and confirmation, payment recording, provider alerts for unpaid claims, and verification of benefits for new patients. The team handles reauthorization alerts and manages claim corrections, retractions, and appeals. A second-tier plan adds full back-office bookkeeping: patient payment tracking, co-pay and deductible management, tax reporting, and monthly account statements. Administrative services, including credentialing assistance, invoicing, and practice form generation, are available as well. The company works exclusively with licensed mental health professionals: psychologists, psychotherapists, Licensed Independent Clinical Social Workers (LICSW), Licensed Marriage and Family Therapists (LMFT), Licensed Mental Health Counselors (LMHC), and Licensed Alcohol and Drug Counselors (LADC). Solo practitioners and multi-provider groups are both supported, with service volume adapted to fit the size of each practice. The Westside Billing team carries a combined 70 years of experience across billing, finance, insurance, and credentialing. Owner Jennifer Gilchrist has 32 years in finance and 15 years specifically in the mental health industry. Benefits Specialist Kendra Bolivar brings 13 years of insurance and claim resolution experience, while Christine Huard contributes over 45 years in contracting and credentialing, with established carrier contacts to move provider applications through quickly. That depth of knowledge, concentrated in a family-owned operation, sets Westside apart from larger, generic medical billing services. Jennifer also serves as the direct customer support contact, keeping communication with providers personal and consistent. For practices looking to outsource billing and cut administrative overhead, Westside Billing offers clear service plan options.
