 Dr. Horst delivered my two sons via C-section and is also my GYN. He is not only an amazing Doctor but such a friendly and loving human being. I love Doctor Horst and highly recommend him to everyone. The office staff is also very friendly and efficient.

Dr. Horst took the time to personalize the visit by inquiring about my children and wishing them a happy birthday…which is coming up. He delivered my first son 15 years ago so the small gesture helped to calm me during a difficult visit. He is very thorough and made sure I understood next steps and possible outcomes. He has been consistent in this way 15 years ago, and still now.

 Dr. Horst is INCREDIBLE! His attention to detail, bedside manner and amazing memory are just a few of his top qualities. I can’t properly express my absolute gratitude to have him as my Dr.
