Had a large laceration required emergency repair at ED. Dr Hazboun was more than amazing. He took his time carefully sutured the laceration together. I could barely see any visible stitches when it was done. Dr Hazboun is friendly, understands fully of patient's needs, and skillful. Just had my post-op checkup, suture removal was almost discomfort-free. Highly recommended if you are looking for a plastic surgeon that takes time understands your needs with excellent hands. The office staff was also great and efficient. Five stars for sure!🌟😃🌟👍🏻🌟🎉🌟🥳🌟

Update: After posting my review, the team reached out to me directly and made sure the situation was fully resolved. I really appreciated their willingness to address my concerns, and follow through to make things right. Initial Review: I recently had an under-eye vein treatment done here, and unfortunately, my experience was very disappointing. After spending $350 on the procedure, I expected to see a noticeable improvement. Instead, the vein under my eye looks essentially the same. When I brought up my concerns, I was told that the area looked “slightly” better, but that felt more like an excuse than an honest assessment. From my perspective, I’m not seeing the level of improvement that would justify the cost of the treatment. I had hoped for transparency and a results-driven approach, but I left feeling let down and dissatisfied with the outcome. Overall, I would not recommend this treatment based on my experience.

I completely trust the kind, personable Dr. Maas and his lovely staff. Peak talent in his field with a professional, well-trained team backing him. Will be his client for as long as he is in the business (which I hope is a long time)!

I cannot say enough good things about my experience with Dr. Corey Maas at the Maas Clinic. My visit was for a consultation regarding a nose injury bump. Dr. Maas is incredibly knowledgeable, professional, and friendly. He listens very well, and, importantly, gave thought to and clear answers about everything I asked, and also other things that he thought I should know, but that I hadn't known to ask, in understandable and patient detail. He gave me a clear plan for going forward, which was important to me. I was very impressed. His assistant, Annie, was also very impressive. His clinic is clean and inviting, his staff professional and friendly. I felt that I was well taken care of as soon as I entered, and all through my visit there. I recommend Dr. Maas very highly.

Maas Clinic is a friendly environment. You feel very comfortable to trust them with your procedures. Dr. Maas is wonderful, he’s friendly and most importantly very skilled. He takes the time to explain and answer all your questions and help with your concerns. You can tell he genuinely cares and wants what’s best for you and understands your situation. Staff are extremely courteous and professional. I love Cassidy, she’s the best! I highly recommend Dr. Maas for all your beauty needs.
