If this is the same Dr. Goldberg that works a few hours a week at Gentle Dental in Cambridge, then I recommend him very highly. I had a terrible experience with the Gentle Dental dentist, but the subsequent work I had there with Dr. Goldberg was fabulous. He was very friendly, easy-going, reassuring, and informed me when he was starting something new. Because I saw him at GD and not his own facility, my rating for the space is low, but he did a great job.
