i don't know Dr. Kuhl personally, but i know him by reputation on the midwife side of things, three ways. First, i went to Lonestar for the midwives program and i loved them. they, in turn, love Dr. Kuhl. they said if not for him, lonestar midwives would not exist. Dr. Kuhl is pretty famous in the san antonio OB world.
Secondly, i know Dr. Kuhl's son. He's Dr. Eric Kuhl, my dentist! I went in for a checkup and explained that i didn't want xrays b/c of pregnancy, etc. and Dr. Kuhl asked who was caring for my pregnancy. when i told him lonestar midwives, he knew them all and told me that his dad was an OB over there. he didn't mention how well-known his dad is, but he was very happy w/ my choice of lonestar midwives.
Thirdly, one of the kids room staff at my gym has known Dr. Kuhl all her life b/c her mom was a private midwife, and Dr. Kuhl was her attending of choice for many years. She'd use Dr. Kuhl in a heartbeat! she delivered w/a midwife for both her kids, and Dr. Kuhl visited her each time he was on rounds, just so he could check on her, even though she was not his patient.
so, i hope this helps with your second opinion. good luck!
