  • "My name is Bruce Greenfield. I am a patient of Dr. Novaselec. Dr. Novaselec is a member of New York Cancer and Blood Specialists. I was recommended to Dr. Novaselec by my former pulmonologist. I am grateful for the recommendation. Dr. Novaselec and his staff are efficient and courteous. Most importantly, they listened to what I the patient had to say. In the old parlance, they have a good bedside manner. The office staff was also courteous and efficient. Although I am being examined in a contemporary medical setting, there is an old world ethereal charm about the setting. At no time did I feel like I was on a conveyor belt. To date, I am the recipient of good news concerning the state of my cancer. Dr. Jennifer Betourney, the radiological oncologist, achieved her goal. I was referred to Dr. Betourney by Dr. Novaselec. They worked as a team. I would also like to give the PA I was assigned a special shout out. Elizabeth called me the day after my blood work was done to give me an overview of the results. Her doing so, illustrates the non-conveyor belt approach to the practice of medicine. Bruce Greenfield New York City August 20, 2025"
