What is Charles River Medical Associates?
Charles River Medical Associates is a physician-led practice at 162 Main St, Northborough, MA 01532. Its main work is adult primary care, and it runs a medical weight management program called EverWell Weight Management alongside it. Gunardi Irawan, DABOM, MD leads the practice and is board-certified in internal medicine and obesity medicine. Courtney Laperriere, PA-C and Diana Kisel, FNP-C work on the same team.
Primary care covers annual physicals, chronic conditions such as blood pressure, diabetes, cholesterol and thyroid, same-day sick visits, and on-site labs and EKG. Follow-ups, refills and non-urgent concerns can also be handled by video for patients anywhere in Massachusetts. Office hours are Monday to Friday, 8:00 AM to 4:30 PM, and the office is closed on weekends. In its own words, the weight program is "A physician-led program, not a diet: body-composition analysis, labs, nutrition and exercise plans built around you, and medication when it helps." The medications it names are phentermine, Qsymia, Contrave, Saxenda, Wegovy and Zepbound.
What does it cost?
It does not publish prices, a consultation fee, or what weight loss medication costs. Most visits are covered by insurance, though the FAQ notes that co-pays and deductibles usually apply. The practice lists these plans: Blue Cross Blue Shield, Harvard Pilgrim, Tufts Health Plan, Mass General Brigham Health Plan, Tufts Medicare Preferred HMO (Medicare Advantage), Aetna, Cigna, UnitedHealthcare and Wellpoint. Plans change, so it asks patients to call (508) 770-6701 to confirm theirs.
What should you ask before you book?
Ask who writes the prescription for each medication, since three clinicians are on the team. Ask whether any monthly fee includes the medication, and whether each drug is the brand-name product or a compounded version. Ask what follow-up visits and lab work cost, since follow-ups are typically scheduled monthly and labs are done on site. Ask whether your plan needs a referral from a primary care provider, and whether the office can help with it if so. Ask how to stop or pause the program, because it does not describe cancellation terms. It lists a second number, (508) 393-1307, for questions, alongside (508) 770-6701.
Who is it a good fit for?
This is a good fit if you want primary care and medical weight management from one team, either in person in Northborough or by video in Massachusetts, and you are comfortable asking about medication costs before you commit. It is worth calling first if you need a price in writing before you book.
