My OBGYN was very helpful and went above and beyond when i came in for heart rate check because i was feeling anxious. She even pulled in the ultra sound machine which i wasnt expecting but gave me so much more ease. I am looking forward to appointments in the future with this provider

Dr.Koehm made it easy to discuss my concerns. She listens and cares and is open to what i say. She had reviewed by blood test before my appointmnt which is nice. She is very knowledgeable, approchable and easy to talk to. Im very glad she is my primary.

Dr Koehm and her nurse [redacted] Were great! I did not feel rushed, i was listened to and explained everything thoroughly before the procedure started and during. Dr. Koehm even took a look at my labs and further explained some things even though they were not explicitly connected to the procedure.

Dr. Koehm always gives us a lot of her time and makes us feel like we're listened to and like our concerns are validated and she's just a good listener and spends a lot of time. Sometimes we do have to wait to see her, but I get it. They're just busy. But once we do get to see her, she spends a lot of time and gives us great care for our whole family, all three of our boys. So we're very grateful to her. We just had a recent hospitalization for the little one and she came down and visited us as well. So she genuinely cares and we feel that. Thank you.
