I've been a loyal patient of Schweiger Dermatology in Smithtown for years and have always had…read morepositive experiences, which is why I felt comfortable booking a same-day appointment at the Deer Park location since it's closer to home. Unfortunately, this visit left me feeling uncomfortable, dismissed, and taken advantage of. I struggle with significant anxiety around doctors, especially in clinical settings, and instead of feeling supported, I felt judged and spoken down to. The provider I met with had very poor bedside manner and made assumptions about me and my body within minutes of meeting me. At one point, she even commented that I was "getting bright red" while questioning me, which only heightened my anxiety. I was too nervous to speak up in the moment. What stood out the most was being told multiple times that I "never have to come back" and could just return to the Smithtown location. That felt unprofessional and dismissive--especially given that I had just paid a significant amount out of pocket for the visit. To make matters worse, I was informed that treatment would require a follow-up appointment, leaving me feeling stuck after spending money on a visit that ultimately didn't help me. I deeply regret not staying with my original location. I've referred many friends and family members to Schweiger Dermatology over the years and truly value the practice as a whole, which is why this experience was so disappointing. I sincerely wish my visit to the Deer Park office had reflected the level of care and compassion I've consistently received elsewhere.

I'm extremely disappointed with this office's billing practices. I was sent to collections over a…read more$40 bill despite never receiving a single phone call, email, or piece of mail about any outstanding balance. Had I been notified even once, I would have paid it immediately. I found out only when the collection agency contacted me.

Absolutely THE WORST front desk experience! Abrasive, dismissive, rude and too busy "doing 3 things…read moreat once" to do any one of them correctly. Horrific front desk staff.

My son and I went in October to see Dr. Dispaltro. He saw both of us in 10 minutes. I told him my…read moreDad has a history of skin cancer and he didn't check us out. He basically dismissed my concerns. my son who is 22 has acne on his chest, back, and arms. He prescribed body wash and gel cream. Said it would probably take 12 weeks to show a difference, but then said to follow up in a month. Why? So he can see him for 5 minutes and charge us? Then when I got bills for our co-pays, I paid them only to get a new bill for both a month later. Both payments cleared my account before the new bill was issued. Now I've been trying to call the billing service for 3 days and it's always busy. I've called over 20 times and I can't get through. I hate this office!!! total incompetence!!!!!!
