I have an infected cyst and the derm said they couldn't do anything for it so they referred me to a surgical derm which could only take it out a month later I can't wait that long with an infected cyst. So I went online and I found this dermatologist location and I'm so glad I did. I had dr, Cerveny and he took out the infection, put me on antibiotics and will remove the root next week when the infection subsides. He and everyone that worked here was so professional, respectful and helpful! Glad I found this helpful new dermatologist!

The office does get busy, even with early appointments so do prepare to wait a bit before going in. The parking situation may be an inconvenience for some as it's super tight and small, but they provide valet service if you feel it'll be a hassle getting in and out which is nice. I had no complaints. The front desk staff were awesome and super friendly. My first impressions of this office was great!

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.

We have been patients of Dr. Glaser for many years and have brought him a variety of problems…read more I remember first visiting Dr. Glaser with fungus on my toe nails. While I was on the medication, he monitored me with blood tests. When an unusual blood platelet reading showed up, he immediately tried to determine if it was caused by the medication. My problem was not listed on the medicine's data sheet as a side effect. But because it could become a serious medical issue, Dr. Glaser called the manufacturer directly. They acknowledged that it was an uncommon and therefore unlisted side effect. He immediately terminated that treatment. Thanks to his insight and his conscientious nature, I was saved from future medical dangers. For years he has been treating sun damage spots on my head; biopsying them, freezing them, removing them, etc. When I needed specialized surgery or plastic surgery because of the nature or extent of cancer cells on my head, he has always sent me to excellent surgeons. He always followed up to make sure I was healing well. Two weeks ago a cluster of painful pimples appeared on my wife's back. The secretary fit us in for a same-day emergency visit. Dr. Glaser knew at a glance that it was a shingles outbreak. A prescription went right to our pharmacy and we left with complete instructions for its care. We have already had two follow-up contacts from Dr. Glaser. It's not just the big stuff he follows up on. I have dry skin on my legs because of bad circulation, so I get reminders to use a lotion on my legs. Anything that is of concern to us, is important to him. Something is always popping up. We are quite comfortable in calling for an emergency appointment. His office staff is very accommodating. We have an ongoing need for a great dermatologist and that is Dr. Glaser.
