  • "Dr. Askin is an amazingly professional, knowledgeable, and respectful doctor. As an educator of 32 years, I can always expect Dr. Askin to test me as to the reason for the appointment. He ensures that I am well informed as to what is or is not transpiring in my body. When appropriate, Dr. Askin provides viable options to resolve, treat, or further investigate any issues I may be experiencing. In addition to all of this, he always makes me laugh. Dr. Askin, as always, this is my message to you: “ “Live like you're loved because you are!”"

      from Monica 5.0 Stars - (2024-06-11)
  • "Dr. Askin appears to be a very warm and reassuring hematologist. During my initial appointment, he took the time to ask all the related questions to fully grasp my medical history and current health concerns. This level of thoroughness is rare to find in other doctors, who often rush through consultations without getting in depth into the patient's situation. The only two doctors that I currently appreciate in my life is him and my current gynecologist who seems to have the same approach as him. Thank you!"
