Meet The Doctors


Approximately 10% of children are born with a significant vascular birthmark that requires the opinion of a specialist. While the severity of each case is different, we pride ourselves in communicating with our patients so that they have as much information as possible.

Our institute has earned a reputation as the go-to clinic for difficult cases, especially those that have been misdiagnosed in the past and patients who have not been able to find an effective treatment for their condition.

We are passionate about helping people and invite anyone who has questions or concerns to reach out to us.

Many infants and children are impacted by various forms of vascular tumors. While many congenital and other vascular tumors are benign, they can cause discomfort and deformity. From the common strawberry mark of an infantile hemangioma, to congenital hemangiomas that can cause bleeding disorders or organ damage, our experts at Vascular Birthmark Institute can offer accurate diagnosis and treatment options at our clinic in New York.

Those born with a congenital birthmark or tumor have options for treatment. Whether you have a very rare form of birthmark such as congenital infiltrating lipomatosis or a more common nevus, you want specialized diagnosis and treatment options. At Vascular Birthmark Institute, we have a team of birthmark and vascular specialists to help treat our patients with congenital birthmarks. Our founders have spent decades researching these diseases and offer innovative treatment options to our patients.

If you are looking for the most advanced and specialized treatment for Hereditary Hemorrhagic Telangiectasia (HHT, Osler-Weber-Rendu Disease), we can help. At the Vascular Birthmark Institute of New York, we extend a wealth of experience and expertise when it comes to all vascular lesions.

We are pleased to offer patients our multidisciplinary team approach to patient care. Our practice includes specialists in otolaryngology, interventional radiology, as well as pediatric and adult hematology-oncology, and pulmonary. Genetic testing is also offered. Dr. O and her team make it a priority to provide world-class care in the diagnosis, treatment, management and research of HHT.

Patient Reviews

A little story about my birthmark is published in different websites like the UK daily mail and foxnews. As I am reading the story and looking back at the photos I cannot do anything, but thinking of how wonderful and amazing you are. Thank you so much for saving my face and life. I greatly appreciate it. There are lots of comments praising the surgeon who did it. Thanks a million.

I had a huge AVM at my upper lip and let me tell you GOD performed a mirracle through Dr. Milton Waner and his team. Not only do they heal you physically but the team mends your soul as well through kindness and empathy. I found the Institute online and I was in touch with the Doctor's PA all the time. The team helped me with the paperwork, suggesting a place to stay, walked me through the procedure, etc. and a few months later I flew in for a surgery. (12000km) The recovery was very fast and the team made sure I was comfortable and well all the time. I've had a lot of experience with surgeries (8) but this one was a smooth one. I highly recommend them!

It has been over two and a half years since you removed my son’s hemangioma and there is rarely a day that goes by that I don’t think about the great care you gave us and how you provided firm answers during a time when we were faced with nothing but questions. After our first visit with you when Evan was three months old, I walked away knowing we were in good hands. Three months later, I held my baby as he received his anesthesia and I clearly remember walking out of the operating room knowing I had found the best team in the world to care for him. I recently visited your Web site and I was once again astounded and grateful for the work that you do. You did such an amazing job removing Evan’s hemangioma and the scar he has is barely visible. You are all such wonderful people and making a difference in the lives of so many people. Thank you for all you are doing. I wanted to share some pictures of Evan with you-please feel free to use them in any way that can help other families or showcase your work. There is a picture of Evan at three months, pre-surgery at six months, immediately post surgery with Dr. Waner, two days post surgery and then today–Evan at three years old.
