Sarcastic. Unwilling to step outside of his specialty for just a small question. Unfriendly. Makes us wait 5 days for his report on me which was "not in his specialty" nor did he treat me . 5 DAYS!!

We liked Dr. Sender a lot. He is a no-nonsense clinician who knows his mission and does it well.

Genuine care for sure! Always looking for your best interest and I never feel rushed. Dr. Sender sits with me and converses with me and we also discuss my concerns.

Dr. Sender paid close attention to my case history. He asked relevant questions. An office ultrasound turned up an anomalous item that he noticed immediately and recommended a relatively new, successful treatment.
