Excellent office!!

Dr Guennette and all staff at the Hartford Health Mystic location are great! The endless telemarketing calls from Hartford Health to schedule home visits, new services etc are annoying, unsuccessful, and costly. The call says it's from Hartford Health so we answer thinking call is actually upcoming from HH but it isn't. The callers are often unable to find open dates for appointments or services offered, frustrating them and us. This increases premium, co-pay and drug costs to age 65+ patients, who often have limited income despite still working to pay for health insurance premiums, services, and high housing costs.
