Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

New Patient: First Appointment
I needed a new cardiologist after mine of 20 years left his practice. Upon contact, Starling called back promptly to set up an appointment. Through interconnected patient portals they already reviewed medical records and told me I didn't need to bring any records with me. Dr. Merkatz was personable. He listened and was informative. I believe he took appropriate action to assess my condition as a new patient. The tests he ordered were consistent with current symptoms I reported and time since previous similar tests. I felt at comfortable that I had made the right choice in a new cardiologist. The Enfield, Ct office personnel all made me feel this was a well run practice that treated patients with a welcoming smile.
