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.

I was referred to Dr. Koster by my OBGYN having no prior information about her as a doctor. The few visits we'd had were pleasant, she was very kind and knowledgeable. The reason for the low rating is because of Dr. Koster's response to my crisis situation. I was admitted to L&D at 22 weeks (2 weeks ahead of viability) with cervical incompetence and bulging membranes. My OB was out of town and Dr. Koster was consulted by the OB on duty. I was advised that Dr. Koster was coming an hour after I was admitted, then updated that she was coming a few hours later, then advised that she'd come in the morning. I'd been in a critical state for 6hrs before my bag ruptured and Dr. Koster never showed up. She later advised that there was nothing she could do, but how can you know if you never show or examine me? She never called to checked on me and subsequently my babies died. She never sent another doctor to do an emergency cerclage or anything! Her lack of care is a disappointment.

-Dr. Koster is knowledgeable, understanding, kind and very relatable. -Small, friendly office environment. -Super, super short wait times. -Very quick turnaround on communication of test results,etc. -Very much a small-town doctor's office feel, but with the knowledge, technology and convenience of a metropolitan office.
