Endocrinology - Staten Island, NY

Endocrinology Services in Staten Island, NY

Endocrinology and metabolism is a medical subspecialty with a keen focus on the glands and hormones of the body.

Every organ system has hormone receptors and, thus, disorders of the endocrine system can affect the whole body – from head to toe!

Common conditions treated by an endocrinologist include diabetes (both type 1 and type 2), thyroid disorders (both hyper- and hypothyroidism), thyroid nodules, polycystic ovary syndrome, and disorders of the pituitary, parathyroid, adrenal, and reproductive glands.

Under the guidance of Philip Otterbeck, M.D., Division Chief of Endocrinology at Richmond University Medical Center, patient care is reaching new levels of expertise.


One of Dr. Otterbeck and his team’s top priorities is addressing the high levels of diabetes – and obesity – on Staten Island.

Indeed, key to helping patients live longer and healthier is to prevent diabetes in the first place. This means all patients should engage in healthy eating and an exercise program consistent with their other medical problems.

Once diagnosed with diabetes, however, efforts aimed at diet and exercise modification must continue. That’s why at Richmond University Medical Center, we have a team of experts to help you every step of the way, who work alongside your doctor to assist in diabetes management. Patients have access to nurses, nurse practitioners, and certified diabetes educators who lend their specific expertise to and coordinate the care of our patients.


Thyroid disorders are common.

Some data suggest that up to two thirds of patients have nodules of the thyroid gland. Many of these nodules remain undetected.

If you or your doctor notices a mass in the front part of your neck, a thyroid ultrasound might help to evaluate the lesion and determine whether or not there is indeed a nodule on the thyroid gland.

In his office, Dr. Otterbeck has the capacity to evaluate the thyroid sonographically and immediately perform an ultrasound-guided fine needle aspiration with topical anesthesia, if a biopsy of the nodule is indicated. Of course, this eliminates the need to make additional appointments with another practitioner waiting for the procedure to be done. What’s more, there’s no need to fast or be off your blood thinners prior to this non-invasive procedure. There are no restrictions after the biopsy – in fact, you can return to work the same day!

The biopsied material is then transmitted to The Mount Sinai Hospital for processing and analyzed by our expert team of pathologists at Richmond University Medical Center.

Of course, the purpose of a biopsy is to rule out thyroid cancer. Fortunately, most patients with thyroid nodules do NOT have cancer – in fact, thyroid cancer is diagnosed in only about 5% of thyroid nodules.

But, should you be diagnosed with thyroid cancer after a biopsy, Dr. Otterbeck works with a multidisciplinary team to coordinate your cancer care. We have top-notch surgeons and anesthesiologists who will ensure a successful operation and the best chance for surgical cure. We also have our own nuclear medicine department who will provide radioactive iodine ablation treatment if it is clinically indicated.

Our patients’ care is coordinated by our expert, friendly staff and organized by our state-of-art electronic medical record, so that your entire medical record is visible to our clinical staff at the stroke of a key.

 At Richmond University Medical Center, our patients are our highest priority. To that end, the Endocrine Division remains committed to excellence in the medical and surgical management of endocrine disorders.

Pediatric Endocrinology

Diabetes. Growth. Reaching puberty. Sudden weight loss or gain. What do these things have in common? They are all affected by your body’s endocrine system, which is responsible for producing and releasing hormones into your bloodstream. A child whose thyroid gland is affected may, for example, have growth delays. Or pre-teens or teenagers may experience early or late puberty. Diabetes is also hormone-directed, since your body’s ability to process sugar is governed by the hormone insulin, produced by the pancreas.
This is where the pediatric endocrinologists at Richmond University Medical Center excel. They diagnose and treat these conditions, and others affected by hormones produced in the body, such as bone disease, calcium imbalances and adrenal disorders. 
What’s most important is that they do this for children and teenagers, which requires special insights. These kinds of disorders, which often affect a person’s appearance — too short, too tall, under- or overdeveloped for a certain age — as well as performance — energy levels, anxiety, and even heart rate — can be debilitating both physically and emotionally for this age group. The doctors at Richmond University Medical Center treat their patients with sensitivity, awareness, and understanding.
If you feel your child is suffering from one of these conditions, call us. With proper diagnosis, treatment, and management, we’ll get your child or teenager back on the track to good health.
