  • 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 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.
