Dr. Giselle Mosnaim is not only an outstanding doctor, but a truly caring person. She is a rare gem! She has been pivotal in my allergy and asthma journey, and I cannot begin to sing her praises enough. Along with her upstanding professionalism and ethics - her bedside manner, compassion and empathy are unmatched - a rarity in today's health system and the medical field. She is extremely knowledgable, detail-oriented, thorough and has a deep understanding of medicine and stays updated on the latest advancements. Throughout the 3 years I have worked with her, she has demonstrated time and time again her unwavering dedication and commitment to her patients, and her willingness to go the extra mile. I enjoy a higher quality of life on a daily basis than I thought possible because of the treatment and care I received as a patient of hers. Dr. Mosnaim has made a lasting positive impact in my life, and the healthcare system as a whole!
