Chang Jack C MD 706 Rogers Street, Lowell, MA 01852

"This guy clearly gets kickbacks for his referrals. He refuses to write letters of referrals to anyone outside his referral network. He's a crock. If you care about your loved ones stay away. Will be happily reporting him for his Stark law violations."

"I don't know how Dr Chang gets the bad review. Both my in-laws go there ,the staffs there are so friendly, provide service very quickly. Dr Chang is very knowledgeable, very easy communicate too.... so much more."

"The worst doctor ever! Lack of Medical Knowledge ( especially medications, knows nothing about how to use them not to mention the side effects.) If a doctor doesn’t know how to prescribe medications then he is not qualified. He always tries to fool the patients. Seems like all he knows is from an out of date oooooold version dictionary. Unprofessional, money-driven, self-righteous, doesn’t care about the patients at all. Doesn’t show any respect to the patient. Always accepting new patients, always losing patients."

"This doctor uses his experience, his knowledge and his intelligence to diag and treat patients, not totally relying on equipment and lab report. He is sharp and humorous. He controlled my blood pressure and cholesterol level well. Recommend!"

"As an active pt for over 5 years, I lost my job in the beginning of the pandemic which ultimately cost me my health insurance. I had an outstanding bill for only 6 months that went straight to collectionsand right on my credit report!!!! I have many more examples of how this office is MONEY driven only. Feel free to contact me through email for any questions."
