“Dr. Chi was amazing- she coached me through the labor. A true professional with the experience every new mommy needs. I will continue to see her for my future appointments.”

“Everyone is so nice at the practise. I have been going there for approximately 10 years now and even though I live a good 45 minutes away, I wouldn’t change doctors. Dr. Chi is amazing! She delivered both my sons and I had a great experience with her as well as with the other doctors at the practise.”

“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.”
