I graduated in 1986 from the University of Ibadan in Nigeria, at the time considered the preeminent medical school in Africa. After undergoing training in ObGyn and practicing in Nigeria, I moved to London, England in 1992. I retrained in England and practiced there. I was fortunate to train and work under Professor Stuart Campbell, internationally known as the father of obstetrical ultrasound, and a pioneer in the field of fetal medicine. It was working with Professor Campbell that stimulated me to pursue a career in maternal fetal medicine. It was during this period at the world famous St. George's Hospital in London that I became interested in academic medicine and research. In London, I was fortunate to work closely with such international giants as Dr. Yves Ville, Dr. Stuart Stanton, Christoph Lees, Tom Bourne, Abdul Sultan, Austin Ugwumadu, Ranee Thakar and Austin Ugwumadu. In 1999, I moved to Washington DC, where I did my residency at Georgetown University Hospital. Following completion of my residency, I moved to the Robert Wood Johnson Medical School where I did my fellowship under Dr. John Smulian and Anthony Vintzileos, both giants in the field of maternal fetal medicine. Upon completion of my fellowship at the Robert Wood Johnson Medical School, I was asked to join the faculty as an Assistant Professor. A few years later, I was promoted to Associate Professor. From 2010 to 2014, I was at the Jersey Shore University Medical Center, where in 2013, I was appointed Director of Maternal Fetal Medicine. In October 2014, I was recruited to Atlantic Health System at the Morristown Medical Center, where I currently am a perinatologist. I have authored over 100 research papers, abstracts and book chapters. I am a reviewer for over 25 of the leading journals in obstetrics. I am also an award-winning photographer, a musician, and music producer.

Learn about Dr. Oyelese
I believe my work is a calling, rather than a "job". I do my utmost to give every patient the very best care that can be provided. Furthermore, I promise to treat you with compassion, patience, and understanding. I try to treat every single patient the way I would want to be treated. I promise to treat you the same way I would treat my own wife, sister, or mother. In order to provide the very best care, I have undergone a lot of training, more than most physicians in our specialty. Going through a high risk pregnancy can often be an extremely scary time for the patient and for those close to her. However, these pregnancies can have good outcomes if the patient is looked after by a competent, compassionate physician. My philsophy has always been to care for the patient with the patient being an equal partner in decision making. In helping you make the best decisions, I will provide you with honest, medically sound information. It is a privilege to care for you!

Why It Matters: Dr. Oyelese's Board Certifications
Board certification should be one of your top considerations when choosing a doctor. Board certification is an official recognition given to doctors who have met specific requirements set by national medical specialty boards in the United States.
Board certification indicates that a doctor is highly qualified in the medical field in which he or she practices. A board-certified doctor is more likely than a non-board-certified doctor to have the most current skills and knowledge about how to treat your medical condition.

What is medical malpractice?
Medical malpractice is issued when negligence by a doctor causes injury to a patient. For example, a doctor may improperly diagnose, treat or medicate outside the standard of medical care. The three types of malpractice are: a settlement, an arbitration award, or a judgment.
If my doctor has malpractice history, does that mean he or she is a poor-quality doctor?
If your doctor has a malpractice claim, evaluate the information and determine if the action could potentially impact the quality of care you receive. Claim settlements and arbitration awards may occur for a variety of reasons, which should not necessarily reflect negatively on the doctor's professional competence or conduct. You may want to use this information to start a discussion with the doctor about his or her history and specific ability to provide healthcare for you.
How far back does Healthgrades malpractice history go?
Healthgrades reports details of a doctor’s malpractice history when the doctor has at least one closed medical malpractice claim within the last five years, even if he or she no longer practices in that state.
For which states does Healthgrades collect malpractice history?
Healthgrades collects malpractice information from California, Colorado, Connecticut, Florida, Georgia, Illinois, Massachusetts, Nevada, New Jersey, New York, North Carolina, Oregon, Tennessee, Texas, Vermont, Virginia, and West Virginia. If your doctor has a malpractice claim, evaluate the information and determine if the action could potentially impact your quality of care. Sometimes multiple states report the same claim. If a provider practices in a state where data is unavailable, please reach out to your local state legislature to help make this data publicly available.
No sanctions history found for the years that Healthgrades collects data.
What is a sanction or disciplinary action?
A sanction, also known as a disciplinary action, is an action taken to punish or restrict a doctor who has demonstrated professional misconduct. Sanctions may be imposed by a state medical board, professional medical licensing organization, or the U.S. Department of Health and Human Services.
If my doctor has sanction history, does that mean he or she is a poor-quality doctor?
If a doctor has a sanction, it does not necessarily mean that he or she is a poor-quality doctor. Some sanctions are not related to medical care, and involve a doctor’s finances or administrative activities. Before you make any choices about changing your doctor, we recommend that you evaluate the doctor’s sanction information and determine how severe or relevant you think the sanction cause and action were.
How far back does Healthgrades sanction history go?
Healthgrades reports state and federal sanctions from the previous five years, except when a doctor's license has been revoked or surrendered. Healthgrades displays all actions for doctors whose licenses have been revoked or surrendered.
For which states does Healthgrades collect sanction history?
Healthgrades collects sanction history from all 50 U.S. states. Physicians with a disciplinary action in one state may move to another state where they have a clean record. Since Healthgrades painstakingly compiles disciplinary action information from all 50 states, Healthgrades website will show if a physician has a disciplinary action in more than one state.
0 Board Actions
No board actions found for the years that Healthgrades collects data.
What are board actions?
Board actions are non-disciplinary actions imposed upon a doctor based on a complaint investigation. A patient or medical colleague may file a complaint with that state medical board or professional licensing organization, which then investigates the complaint. Board actions are intended to ensure that a doctor is able to perform safe medical and health care tasks.
Types of non-disciplinary actions include an advisory letter, a corrective action agreement, a limitation or restriction on the medical or healthcare tasks a doctor can perform, or a voluntary agreement by the doctor not to practice. A board action can also include a termination of a corrective action agreement or voluntary agreement, which allows the doctor to return to full practice.
If my doctor has a board action, does that mean he or she is a poor-quality doctor?
If a doctor has a board action, it means he or she has had a non-disciplinary action imposed upon him or her. It does not necessarily mean that he or she is a poor quality doctor. Before you make any choices about changing your doctor, evaluate the doctor's board action information and determine how severe or relevant you think the cause and action were.
How far back does Healthgrades non-disciplinary board action history go?
Healthgrades reports non-disciplinary board action history from for the previous five years, except when a doctor's license has been revoked or surrendered. Healthgrades displays all actions for doctors whose licenses have been revoked or surrendered.
For which states does Healthgrades collect non-disciplinary board actions?
Healthgrades collects non-disciplinary board actions from all 50 U.S. states.
