Rocky Mountain Perinatal Associates is primarily a consultative practice, meaning that we work with your obstetrical caregiver to develop a pregnancy management plan for your high risk pregnancy. This enables you to remain, in most cases, under the care of your primary caregiver. Sometimes, if your obstetrical caregiver feels that your pregnancy is at enough risk, he/she may transfer you to Rocky Mountain Perinatal Associates for your entire OB care, including delivery. Generally, your obstetrical caregiver will determine, in discussions with you during your prenatal care, whether you should be referred to Rocky Mountain Perinatal Associates for a consultation.
What is a Perinatologist (Maternal Fetal Medicine Specialist)?: A perinatologist is a physician who has completed two to three years of special training in treating complicated or high risk pregnancies. During this specialized training, there is intensive education and practical experience in treating pregnancy complications; performing procedures such as amniocentesis and chorionic villous sampling; and doing research in the field of high risk pregnancies.
Following the speciality training (the “fellowship”), and after practicing in the specialty for a year, the perinatologist is given an exam by a panel of experts from the field and, upon passing the exam, is “Board Certified in Perinatology.”
