This is the worst physician's office from staff to physician. Everything is set up to bring the physician money and more money. I'm in the health field and writing this review. If you need anything or having a medical issue, you will need to wait 3 months or go to the ER. Office staff is very rude. I've referred my friends and patients and sorry that I did. We are all going elsewhere to a compassionate office staff and physician.

Dr. DeMarchi has been my physician for the last five years. In my experience I have found him to listen and be involved in all aspects of my health care.I have gotten my lab work efficiently done at his office. The office staff have always been helpful, and great for getting referrals to other specialists quickly which is important when you're on Medicare. I have recommended this doctor to 3 people who all are returning patients like me. The doctor is down to earth & easy to talk to.

Rude office manager. Long wait time. No call backs.
Boca Raton, FL |
Went into the office for standard checkup (blood) work. 3 weeks later I had not received any contact from the Dr office. Called 7 times and still had no results. I was told the that they could not find my blood results. Then they said they would call the following day, they did not. Finally, spoke to office manager, still no results.

Dr. Demarchi's practice has several nice amenities; however, there are just too many important problems. Some staff members are not courteous or professional. The office manager is just disrespectful & patronizing. The wait time is usually an hour. When calling, the hold time is consistently 20 min or longer. Overall, the atmosphere generates frustration & discomfort. I would not refer him to my family or friends. After only a few months, I am already looking for another primary care physician.

Dr. Demarchi spends time with each patient. He listens carefully and asks appropriate questions. He doesn't spend the entire time staring at a computer or his phone. He actually uses a pen! He was very intuitive to my particular needs and I feel very comfortable with him.

Be prepared for battle with his front office staff. They are, without question, the most unprofessional and miserable staff (and let's face it, that's simply what you are, staff). While the office itself is elaborate and well-maintained, I can only assume (hope) that the staff will necessitate a downsize in facilities.

The quality of care at this office is horrible. I was sent to a specialist and scheduled for surgery. I needed clearance and follow-up from his office. I called for weeks and did not receive any answers regarding lab work. The office staff is rude,they take messages and never call back. Due to their negligence my care is delayed and I had to postpone surgery. He should not be in practice. I feel sorry for all of the patients that suffer in his care.

ILeft 2 msgs for DeMarchi after cancer diagnosis. No call back. Not like I have the sniffles. Office staff is the absolute worst. They leave you on hold for 20-30 minutes, say they'll call you but don't & lied many times abt getting my referral. Filed complaint with insurance on him. This is how they take care of their patience. Patty even said since I'm unhappy about not getting my referral for one of the doctors to treat my cancer I should find another doctor. Heed the warnings.
Staff help is rude and if you get pattie on the phone beware her phone etiquette is not the best. I would choose another doctor because dealing with the staff at the front desk is horrible.

Office personnel are rude, wait time are long. Unnecessary test done to collect from insurance companies
