Reviews from our happy Patients

Healthy Patients... Healthy Lifestyles!
  • I’m old enough to remember when doctors were not so pressed for time and insurance coverage was not the devil in the closet. This program, and Dr. Seidelman specifically, give me the feeling of security in my health care. I trust her and like her. Knowing you are being listened to is a good thing. What more can be said…

  • I’ve been going to Dr.Tauber for over fifteen years and like his practice very much. His office is as well run as he is, and I’ve told him so many times. He is good and friendly, and runs a complete physical  exam…His asking the questions as part of the comprehensive exam, helps the patient identify the health problem. Never feel rushed, Dr.  Tauber is geniunely interested and takes the time to explore options. Appointments are well run and tight. He does several of the tests there, blood and urine and EKG, so there’s no waiting for the results, they call you the following day. An elderly patient would be treated well here because ANY-aged person is treated well here.  I’ve told Dr. Tauber, that his excellence is made visible in his selection of staff, all ages and colors, a nice group of seasoned technicians. You move along through your appointment, everybody is interested in the patient. Dr. Tauber is a PPO with my medical insurance,  that’s how I was  lucky enough to find him.

  • I have been using Dr. Oser as my internist for almost 20 years and could not be happier. He has always been up to date with the latest research and has always been available to spend whatever time he needs to spend with me when u come in for a visit, be it routine follow up or if I am sick.   On occasion I have had to be seen on days when Dr. Oser was not in the office and I have always been very pleased with his associates. I would not hesitate to recommend Dr. Oser to anyone.

  • Dr. Seidelman is the best doctor I’ve ever had – and I’m 69 years old!

    Sherry C.

  • I am pleased with the current arrangement because the clinicians in the practice provide excellent, timely care, and I have been able to count on them when needed. As a physician myself, I recognize and appreciate a high level of competence and concern in medical practice from the doctors in this group.
