See what it's like to be an ARMC ObGyn Resident - Follow us on Instagram!  



The residency program in Obstetrics and Gynecology consists of four years of training in an accredited, post-graduate program.


The focus of our program is the management of acute and chronic problems with special emphasis on healthcare maintenance and disease prevention.  Our graduates are well prepared to provide general obstetric and gynecologic services.  They will possess the clinical knowledge, surgical skills and attitudes required to function as board certified obstetrician-gynecologists to ensure the highest quality of patient care. 


To educate the resident in the discipline of obstetrics and gynecology and to foster a lifelong commitment to the promotion of women’s health care.

The program is accredited by the ACGME, and participates in the National Residency Match Program (NRMP) through ERAS.


For > 5 prior graduating years.



Arrowhead Regional Medical Center: Base institution


ARMC, base institution for the residency occupies a 67 acre campus which includes a 456-bed facility, a 54-bed Diagnostic and Treatment Center, a 3-story Outpatient Clinic, a 90-bed Behavioral Health facility and a 24,700 square foot central plant.  This state of the art tertiary care teaching facility replaced the San Bernardino County Medical Center when it opened in 1998 and is owned and operated by the County of San Bernardino to serve the residents of this large county in Southern California.  It offers the latest in patient care, providing a full range of services including primary and specialty care, trauma and emergency services, ancillary and Home Health services, Behavioral Health, a regional burn center and a comprehensive Women’s Health program.  The hospital has more than 250,000 outpatient visits per year. There are over 2,500 births per year at ARMC, over 10,000 obstetric emergency room visits, and a level 3 NICU. ARMC is able to care for neonates at the limits of viability, and regularly accepts transfers for higher level care from other hospitals in the area.

Acascio Fertility Center

Dr. Acacio has had some of the highest IVF success rates in Southern California. His outstanding academic credentials and extensive clinical experience have been vital in achieving major breakthroughs and successes in many challenging cases that have failed prior treatments. Highly respected by his peers, Dr. Acacio is often consulted by other physicians who come to him for infertility evaluation and treatment.

Obstetric Rotation - ARMC

While the resident is assigned to the obstetric rotation, their primary responsibility will be running the labor and delivery.  This will include assigning patients to junior house staff, antenatal testing and the management of obstetric patients.

The resident will gain proficiency in normal spontaneous vaginal deliveries, operative vaginal deliveries, and cesarean section.  The experience will also include postpartum tubal ligations, dilation and curettage for incomplete miscarriages, cerclage and amniocentesis.  The obstetrical resident works under the supervision of the in-house attending physician. 

Rounds are used as a platform to introduce pertinent issues in basic science, physiology and pathology of various pregnancy conditions. 

Gynecologic Surgery - ARMC

Gynecologic surgery is a continuum of the outpatient gynecologic clinic.  Residents evaluate patients, form differential diagnoses, begin to utilize and formulate appropriate testing and, if indicated, initiate surgical approaches.  These surgical approaches will be discussed with attending staff.  The resident will function as either primary surgeon or assistant, depending upon the case and the resident’s skill level.

This surgical exposure will span all subspecialties of gynecology, including oncology, reproductive endocrinology and uro-gynecology.  It is expected that the resident will be able to precisely summarize the patient’s complaint, present a differential diagnosis, order appropriate testing to confirm the diagnosis and discuss all aspects of surgical treatment with the attending staff. 

As with the obstetric rotation, rounds will be used as a platform to introduce and discuss those principals of basic science, physiology and pathology as applies to those gynecologic conditions.  Also as with the obstetric rotation, residents are encouraged to lead and participate in these discussions.


Maternal-Fetal Medicine - ARMC

Maternal-Fetal Medicine subspecialty exposure is provided on a continual basis throughout the entire program.  Our department generally has three board-certified Maternal-Fetal specialists who directly supervise the obstetric clinics, both routine and high-risk, as well as the labor and delivery suites and antenatal unit. 

We are also proud of out MFM Fellowship Training program!

Reproductive Endocrinology - Acascio Fertility 

The reproductive endocrinologist works with the residents in formulation of differential diagnoses and design of treatment modalities. Residents will also get to participate in surgical cases that are generally managed by this sub-specialty.


Urology/Uro-Gynecology - ARMC

Training is on a continual basis throughout the four-year program, staffed by attendings with experience in the pelvic reconstruction and uro-gynecological diagnosis and treatment.  The resident will learn to formulate differential diagnoses, administer and interpret cystometrograms, and propose and execute various forms of bladder-neck suspension and pelvic reconstruction. 

Ultrasound - ARMC

Obstetric and gynecologic ultrasound is a daily part of residency training. Attendings with experience in advanced ultrasound supervise and guide the hands on experience so that residents are competent and proficient in the provision of basic obstetric and gynecologic ultrasound at the conclusion of their training. The ultrasound practice is accredited by the American Institute of Ultrasound in Medicine (AIUM).



In the equation between education and service, protected educational time will be set aside for all residents. 


Resident Lectures

The core curriculum in obstetrics and gynecology will be presented in the form of a lecture every Friday between 1:30 and 4:30 p.m. 


Didactic conferences, provided by attending faculty as well as guest lecturers, are presented in general obstetrics, maternal-fetal medicine, general gynecology, pathology, gynecologic oncology, endocrinology and multiple primary care topics.  Additional conferences include Perinatal Grand Rounds, core competencies lectures and tumor board conferences.


Residents are excused from routine clinical activities at both hospitals during resident didactics; therefore absences from these conferences will be excused only for illness, vacations, off-service rotations, or at the discretion of faculty to allow for necessary coverage of emergency cases.


Journal Club

Journal club is held at least 4 times/year and is an event in which residents and attending physicians meet to discuss current advances and controversies in ob/gyn literature.  Residents will participate each month by selecting and presenting articles of their choosing in a standardized format.


Textbooks, Journals and Computer Education

There is no required reading or assigned textbooks for the program.  It is expected however, that each resident will have reference books and will supplement this information with reading from ob/gyn articles as well as internet library access to online text, journals, reference sites. An education allowance is also provided annually to each resident.


The program follows a work hour policy consistent with the ACGME guide regarding clinical hours and education hours.
