Dr. David Anthony Greuner is the managing director and co-founder of NYC Surgical Associates. He is a double board certified surgeon with over 10 years of experience. His post graduate residency training was performed at University of Arizona and Mount Sinai School of Medicine affiliate hospitals (Morristown Memorial Hospital) where he was named chief resident of the year, and won the Hughes Dougan award for dedication to patient care and excellence in surgical technique his chief year.

Dr. Greuner performed two fellowships after his 5 year residency in General Surgery. A two year fellowship in Cardiovascular and Thoracic Surgery at Albert Einstein School of Medicine in New York City, and a Body Contouring fellowship with Dr. Victor Rosenburg in New York City. Although Dr. Greuner’s surgical training and practice encompasses a broad base of surgical procedures; his area of interest lies specifically 2 main areas, endovascular (no incision) vascular surgery, particularly endovenous procedures, complex body wall reconstruction and hernia surgery, especially redo procedures and procedures after massive weight loss.

Dr. Greuner is a specialist at re-do and failed hernia repairs in the past. He has pioneered techniques such as the Slim-Line Hernia repair, where he performs hernia repair on the abdominal wall through a tummy tuck incision for maximum cosmetic benefit while addressing the medical problem. Hernias are a major cause of inefficient muscular contraction, as well as asymmetry in the abdominal wall. To take his body wall surgery and expertise one step further Dr. Greuner also performed a Body Contouring Fellowship with Dr. Victor Rosenburg, one of the most experienced and reputable Plastic and Reconstructive surgeons in the NYC metro area, to help him achieve ideal symmetry, and physical benefit while also restoring the functional components of the patients plagued with hernias to achieve the most ideal, functional muscular contraction.

He has also developed other novel techniques such as the No Knife EVLT, a procedure that he pioneered and perfected to be able to seal diseased veins with a catheter so small it fits through a needle no larger than that used to draw blood. This technique has been featured in many major publications and national TV broadcasts showcasing its superiority over traditional methods, and NYC Surgical is the only practice in the world using this technique.

Dr. Greuner also pioneered one of the largest lipedema surgical programs in the country and is one of the handful of surgeons in the world trained in lymph sparing liposuction for this disease as well as other soft tissue disorders.

Dr. Greuner is passionate about utilizing the most modern and minimally invasive techniques available to accomplish the surgical problem at hand, and when more than a tiny scar is inevitable, he does his best to place it in the most inconspicuous place, such as below the belt line, or in the armpit to avoid disfiguring his patients. While performing surgical procedures through a non-traditional incision is very challenging, he has become adept at doing just that, and in doing so, protects his patients from unsightly scars.

He trained with pioneers in minimally invasive and robotic (laparoscopic and endovascular) surgery, and has performed thousands of these procedures successfully. His passion in medicine is improving minimally invasive surgical techniques for less downtime and better results.

He was voted a “Top Surgeon” by the Consumers Research Council of America 6 years in a row, 2010-2015.

Dr. Greuner is active in continuing medical education, and lectures on a variety of surgical topics nationwide, including speaking engagements at Harvard University hospitals.

He is a diplomate of the American Board of Surgery, a member of the American Academy of Cosmetic Surgery, a fellow of the International College of Surgeons, and a member of the following societies:

  • American Medical Association
  • New York Medical Association
  • Society of Thoracic Surgeons
  • New York Thoracic Surgical Society
  • Society for Laser Medicine and Surgery
  • International Society for Vascular Surgery
  • Society for Laser Medicine and Surgery
  • American College of Surgeons

He is licensed to practice medicine and surgery in New York, New Jersey, Connecticut, Massachusetts, Florida, California and Arizona.

Dr. Greuner speaks Spanish and English, as well as conversational Portuguese. His interests outside medicine include physical fitness, skiing, snowboarding, travelling, photography, and cycling. He is an avid but amateur athlete regular participating in triathlons and competitive events, mostly for charitable causes.

Due to his acknowledged expertise in minimally invasive and cardiovascular surgery, Dr. Greuner is regularly quoted in articles in major magazines and newspapers, and he has made frequent appearances on national television programs such as CBS’s “The Doctors”, the “Dr. Oz” show, Eyewitness News, and PIX 11.

What can I do about my Varicose Veins?

As the summer approaches and people start to get out their warm weather clothing, many will be surprised and mortified to find varicose veins. These unsightly blue veins can cause a lot of discomfort and embarrassment. It’s hard to enjoy the warm weather if you are either too ashamed to show your legs, or wear long pants in the summer heat to cover up your legs.

There are various causes of varicose veins. These happens due to valvular incompetence of the enlarged veins. Normal veins contain small valves, which are designed to keep blood flowing in one direction. If these valves stop working properly, usually as a result of age related vein enlargement, the result is backed up blood, which enlarges the veins further. Many people think these aren’t serious, but left untreated, they can lead to blood clotting, skin changes, and ulcers.

If you live in the New York or New Jersey metro areas, you are in luck. New York City varicose vein treatment is quick and painless. Our surgeons use cutting edge, incisionless, minimally invasive procedures, which treat the offending vein so your legs will look normal again. There are many self proclaimed “specialists” in the area of vein disease or phlebology, but be wary and find out about your surgeon’s training. NYC Surgical Associates is led by a board certified, fellowship trained Cardiovascular surgeon, and only fully trained surgeons are in our practice.

Those who are interested in NYC spider veins treatment need to look no further than our website, which can be found at http://www.veincenters.net. There you’ll find all the information you need to successfully get rid of your varicose veins, so you can be ready to show your legs in no time at all.

We have two offices, one in New York, on Second Avenue, and one in New Jersey, on Passaic Ave in West Caldwell. If you are interested in getting top notch treatment, then look no further than the aforementioned website. We’ve been helping clients for years, and we can quickly take care of your problems.

Many people are hesitant to seek medical help because they don’t know that varicose vein treatment is covered by insurance. Most patients are unaware that insurance can pay for not only the initial consultation but the treatment as well, if you meet the correct criteria. You’ve truly got nothing to lose.

Using our minimally invasive, scarless, FDA approved outpatient treatment that only takes twenty minutes, we are happy to address your problems. It’s painless, and you’ll be rid of your varicose veins in no time.


David Greuner consulted on Amy Winehouse’s last days

Amy Winehouse spent the last week of her short and troubled life in an alcoholic, drug-fueled fog — which she capped by purchasing a stockpile of powerful narcotics at a London bar just hours before her death, according to British news reports.

Her final days were squandered in such a haze that even those who had watched her tumble from the top of the charts to a 27-year-old train wreck were left stunned.

“She has spent the last seven days on a massive bender, and people were saying she’s going to drink herself to death,” one friend told the Mirror.

The final straw may have been a lethal combination of booze and a “bad” ecstasy pill, according to friends with her just before she was found dead.

That dangerous blend came after she was spotted buying drugs from a well-known dealer, the British tabloid The People reported.

Those drugs included cocaine, ecstasy, heroin and ketamine, an animal tranquilizer that is taken illegally for its psychedelic effects.

And the cause of her most recent drug and alcohol frenzy may have been a broken heart.

The soul singer was reeling from her breakup with Reg Traviss, the film director she had once asked to marry her.

Traviss dumped Winehouse less than a month ago, right before she checked into The Priory, a London hospital that treats addictions.

He broke up with her after deciding she would never clean up her act — leaving her “inconsolable,” according to the Daily Mail.

Authorities have not officially determined the cause of her death. But her mother, Janis, told the Mirror it was “only a matter of time” before her daughter’s addiction took her life.

Winehouse took comfort in the fact that she saw her daughter the day before she died — even though it was clear the drugs had taken their toll.

“She seemed out of it,” said the mom. “But her passing so suddenly still hasn’t hit me.”

Her last words to her mother were “I love you, Mum.”

Her dad, Mitch Winehouse, a singer who was in New York to play a gig at the Blue Note jazz club, said, “I’m devastated. It’s such a shock.”

The vintage-styled singer belted her way to international stardom with the release of her sophomore effort “Back to Black” in 2006.

But just as quickly, her undeniable talent was overshadowed by her serious substance abuse problems.

Fans waited for a comeback, but it never came.

Her longtime bodyguard is believed to have found her body, the Mirror said.

Authorities are expected to perform an autopsy today.

The singer suffered from emphysema, which is rare in young people. But smoking crack can lead to the deadly lung disease developing earlier.

Winehouse was once secretly videotaped smoking crack by the British tabloid The Sun.

If Winehouse did pop a combo of ecstasy and booze, as her friends said, that could have been what ultimately ended her life, said David Greuner, a cardiac surgeon at Beth Israel Hospital in Boston.

“Ecstasy and booze dehydrate you, and both have an effect on your liver and kidneys,” said Greuner, who was not involved in her treatment. “Your heart has to work twice as hard.”

Dr. Ryan Neinstein, MD, FRCSC
Founder, Neinstein Plastic Surgery

dr-ryan-neinstein-mdDr. Ryan Neinstein is the founder of Neinstein Plastic Surgery, a state of the art facility combining the latest advances in minimally invasive liposuction and non-surgical aesthetic medicine. Dr. Neinstein focuses on minimally invasive liposuction. His unique combination of acoustic and laser energy pushes the envelope on body contouring procedures, while at the same time allows for virtually no scarring, no general anesthesia and only 48 hours of downtime. This method was designed for the demands of the busy New York lifestyle.

Dr. Neinstein brings a unique and youthful approach to plastic surgery. He is dedicated to the overall health and wellness of his patients and believes plastic surgery should complement each patient’s lifestyle. He believes meditation before surgery improves concentration and critical thinking. This distinctive method has attracted a high caliber of clientele, which includes the likes of national television hosts and broadcast correspondents, fashion models, actors and even other dermatologists and plastic surgeons.

Dr. Neinstein’s commitment to becoming a surgical master in the art of liposuction can be summed up on his view on mastering a skill. Dr. Neinstein states, “Many surgeons choose to be good at many operations but not a true master in one. Surgical mastery is about familiarity and judgment. You learn the problems that can occur during a particular procedure or with a particular condition, and you learn how to predict and prevent these experiences. This can only occur with experience. Expertise is not a static condition, but one that doctors must build and sustain for themselves.”

Non-surgical face and body services and procedures offered at Neinstein Plastic Surgery include: BOTOX®, Xeomin®, Dysport®, Restylane®, JUVÉDERM®, microneedling, collagen induction therapy and medical-grade skincare products. Neinstein Plastic Surgery also offers patients the ultimate face and bodytightening solution, the Venus Legacy Laser. Combining all of these modalities allows Dr. Neinstein to comprehensively treat each patient’s unique needs.

Dr. Neinstein hails from Canada and received his plastic surgery training at the esteemed University of Toronto Plastic and Reconstructive Surgery Program. After his surgical residency, Dr. Neinstein was selected to become one of only two fellows at the most prestigious aesthetic surgery facility in the world – the Manhattan Eye, Ear and Throat Hospital. There, Dr. Neinstein was trained in the most advanced aesthetic surgical techniques of the face, nose, breast and body – a skill set that he brings to each and every one of his patients.

With a commitment to surgical education and a passion for pushing boundaries, Dr. Neinstein is actively involved in clinical research. He is frequently asked to lecture both nationally and internationally. He has authored two textbook chapters on liposuction, most recently this year, focusing on evolving concepts in techniques and technology for the expert liposuction surgeon.

Dr. Neinstein lives in New York City and enjoys surfing, skiing and meditation.
