"Doctors like Dr. Syali are becoming an increasingly rare find. Caring, thorough and most importantly, a very smart, think outside the box doctor. (Great staff too - particularly his PA, Ashley) His specialty is Hematology/oncology but I would consult with him for any health issue someone else might miss. Can not recommend this doctor enough and I have never left a Dr review before. That says a lot!"

"Dr Syali, as well as his entire staff is incredible ! Very, very thorough, pleasant, responsive and helpful in every way. I am a new patient and couldn’t be happier with the care and concern I am receiving. All my appointments for tests and associates has been at Lightning speed, which is not typical, as it should be, in the medical field these days. Very refreshing, especially when not knowing if you have a serious issue weighs on your mind, anywhere knowing as soon as possible is of course paramount.
Keep up the good work !
James J. Nazzaro."
