"Had an amazing experience at Dr. Heiss’ office! This started from before even stepping foot in the office, with the patient coordinator Tammy whom kindly reached out to me a few days before my appointment to confirm my information & insurance. Tammy took the extra step to assure me that Dr. Heiss was in-network and that I should have zero extra charges. The dental assistance Stephanie was super nice and welcoming, made me feel comfortable from the moment I walked into the exam room. Dr Heiss has amazing bed-side manners, and was sure to explain everything that was being done. I am happy to say I had an amazing first experience, and will be recommending Dr. Heiss and his staff to my friends and family!! 10/10 experience."

He is an incredibly knowledgeable and professional dentist who takes the time to walk you through the process so you know exactly what to expect. His friendly staff made me feel comfortable from start to finish - from the warm welcome at the front desk to the calm, reassuring care of the dental hygienist. Everyone was a pleasure to work with. Thank you, Dr. Heiss, for making my smile pearly white just in time for my big day!"

"Dr. Heiss was absolutely amazing! Since my dentist retired, I have been bouncing around from dentist to dentist. I don’t need to do that anymore! I found the one and only! I take pride in my teeth and smile. Dr. Heiss thoroughly explained everything about each tooth through his examination! The cleaning was one of the best I ever had! I already booked my six-month checkup and look forward to him being my forever dentist! Run to his office. He won’t disappoint!"
- Lisa S.
"I was greeted warmly by the entire staff, including Dr. Michael Heiss, Marie, and Tammy. Tammy took a comprehensive set of X-rays with ease. Dr. Heiss examined the x-rays and my teeth and fully and confidently explained what needed further treatment and the plan of action to get there. His calm and thorough manner put me at ease during an in-depth cleaning. Finally, home care instructions were given to prevent future dental issues. I fully recommend Long Island Dental Excellence as a place to receive a highly professional and caring dental experience."

"My former dentist retired and I found out about Dentist Michael Heiss from my daughter’s dentist staff. I had my first appointment with him this week. The staff are very friendly and helpful. I do feel anxious when I go to the dentist and from the moment he came in the exam room Michael Heiss put me at ease. He explained everything he was doing and what to expect. I had a very positive experience and would recommend this practice to others!"
