Our Services



An echocardiogram uses sound waves to produce images of your heart. This commonly used test allows your doctor to see how your heart is beating and pumping blood. Your doctor can use the images from an echocardiogram to identify various abnormalities in the heart muscle and valves. A transthoracic echocardiogram is a standard, noninvasive echocardiogram. A technician (sonographer) spreads gel on your chest and then presses a device known as a transducer firmly against your skin, aiming an ultrasound beam through your chest to your heart. The transducer records the sound wave echoes your heart produces. A computer converts the echoes into moving images on a monitor. If your lungs or ribs block the view, a small amount of intravenous dye may be used to improve the images. A doppler echocardiogram is when sound waves bounce off blood cells moving through your heart and blood vessels, they change pitch. These changes (Doppler signals) can help your doctor measure the speed and direction of the blood flow in your heart. Doppler techniques are used in most transthoracic and transesophageal echocardiograms, and can check blood flow problems and blood pressures in the arteries of your heart that traditional ultrasound might not detect.

Cardiac Stress Testing

A stress test, also called an exercise stress test, is used to gather information about how well your heart works during physical activity. Because exercise makes your heart pump harder and faster than it does during most daily activities, an exercise stress test can reveal problems within your heart that might not be noticeable otherwise. An exercise stress test usually involves walking on a treadmill or riding a stationary bike while your heart rhythm, blood pressure and breathing are monitored. Your doctor may recommend an exercise stress test if he or she suspects you have coronary artery disease or an irregular heart rhythm (arrhythmia). An exercise stress test may also be used to guide your treatment if you've already been diagnosed with a heart condition. Some heart problems, particularly those involving the coronary arteries that supply blood to your heart muscle, occur only during physical activity. For a stress echocardiogram, ultrasound images of your heart are taken before and immediately after walking on a treadmill or riding a stationary bike. If you're unable to exercise, you may get an injection of a medication to make your heart work as hard as if you were exercising.

Carotid Ultrasound

Carotid ultrasound is a safe, painless procedure that uses sound waves to examine the structure and function of the carotid arteries in your neck. Your two carotid arteries are located on each side of your neck. Carotid arteries deliver blood from your heart to your brain. Carotid ultrasound is usually used to test for blocked or narrowed carotid arteries, which can indicate an increased risk of stroke. Results from a carotid ultrasound can help your doctor determine what kind of treatment you may need to lower your risk of stroke.


Skin Biopsies

A skin biopsy removes cells or skin samples from the surface of your body. The sample taken from a skin biopsy is examined to provide information about your medical condition. A doctor uses a skin biopsy to diagnose or rule out certain skin conditions and diseases. Three main types of skin biopsies are: Shave biopsy. A doctor uses a tool similar to a razor to remove a small section of the top layers of skin (epidermis and a portion of the dermis). Punch biopsy. A doctor uses a circular tool to remove a small section of skin including deeper layers (epidermis, dermis and superficial fat). Excisional biopsy. A doctor uses a small knife (scalpel) to remove an entire lump or an area of abnormal skin, including a portion of normal skin down to or through the fatty layer of skin.

We remove a variety of common skin lesions including skin tags, common warts, actinic keratoses, ganglion cysts, among others.


Joint Injections

Cortisone shots are injections that may help relieve pain and inflammation in a specific area of your body. Cortisone shots are most commonly given in joints such as your ankle, elbow, hip, knee, shoulder, spine and wrist. Even the small joints in your hands and feet may benefit from cortisone shots. Cortisone shots usually include a corticosteroid medication and a local anesthetic. In many cases, cortisone shots can be administered in your doctor's office. However, the number of cortisone shots you can receive in one year may be limited because of potential side effects from the medication.
