We (my husband and I) were sent to Erin to take a second look at two brain cysts. Within one week of being found by my original OBGYN, Erin found that one cyst had resolved itself and the other had shrunk and was almost gone..... After telling us not to worry about the cysts, she takes a measurement of the femur bone and tells us our baby might have Down's syndrome and we need a $2000 blood test to find out for sure. When going over our options, she also mentioned ending the pregnancy if the blood test is positive, and that she could find us a doctor to give a 25week abortion! This is all during our first visit! She didn't get to know us at all, she was very cookie-cutter and quick! Consulting with my OBGYN after seeing Erin, he assured us that we had nothing to be worried about and told us Erin should not have conducted our appointment like she did! We will not be returning, and will find a different doctor should we have a need in the future!

Can't say enough good things about Dr. Koster. The personal attention and small office made us feel like she was focused 100% on us and not part of an assembly line like so many other Doctor's offices.

This doctor is AWESOME and I almost want to have another baby just so that I can have an excuse to see her again! She's lovely, detail oriented, very professional yet personable! She answered my questions after hours on her personal time and didn't even bill me for the phone conversation! She is wonderful!

First, Dr. Koster is the most approachable doctor I have ever encountered. She was informative, friendly and really made me feel at ease. I am an older mother and was very nervous about the possiblity of my baby having problems. She was very empathetic and knowledgeable! I would highly recommend Dr. Koster to any mother!!

I love Dr. Koster, I especially appreciated the short wait time, 10 min seems unreal to wait in a Drs. office. She was very kind, caring and concerned for my health and the health of my baby. Her medical expertise helped ease my mind about worrying about my baby. I would hightly recommend her.

Dr. Koster takes amazing care of all of my low and high risk OB patients as needed. Everyone of my patients comes back raving about their visit with Dr. Koster and how much they liked their experience with her and her staff. They feel well informed and reassured about their pregnancies.

Dr. Koster is without a doubt one of the best experts in her field. She is so kind and compassionate and very thorough in her exams. I couldn't have asked for a better experience with her.
