“I wanted to be a doctor so I could help people feel better. I wanted to be a plastic surgeon so I could repair people’s bodies, in ways big and small, not just to improve their looks, but to help them align their physical appearance with their internal perception of themselves. I consider it an honor and a privilege to serve my patients, and I never take for granted the ability to change people’s lives for the better.”

What our patients say about us

I can't express how much I love this practice! I have seen their Physician Assistant Stephanie and she is the BEST! My lips were always an insecurity of mine and Stephanie made them look beautiful by using Juvederm. She knew exactly what product to use, and how much product to use to make them look perfect. She informed me before hand on what to expect and made me totally prepared before the procedure. I felt comfortable and in great hands with Stephanie. I will recommend all of my friends to come to this office! They are so professional from the moment you make the appointment on the phone, to the time you walk out the door. Overall a VERY happy patient!

After needing a double mastectomy due to breast cancer, Dr. Rosen helped me navigate through everything that came next. He was patient, caring, compassionate and professional. His staff were all amazing! Every single person I had contact with in that office was absolutely incredible. I recommend him to everyone I know!

After wanting to get lip injections for over 2 years, I finally decided to give it a try. I am so incredibly happy that I chose The Plastic Surgery Group for this experience. Stephanie made me feel 100% comfortable from the moment I met with her. She answered ever question I had and made sure that I understood the complete procedure from start to finish. To my surprise there was barely any pain. She took her time and made sure to achieve the exact look that I wanted. She also texted me the day after to see how everything was going and if I was happy with the results. I absolutely love my lips now and couldn't be happier with my whole experience. I will be going back to her for any and all injectables in the future. Thank you again!! ?

I am so happy that I have found the Plastic Surgery Group. I have never had any surgical or non-surgical procedures done before but have always been self-conscious about my stomach. I knew that I did not need liposuction, like a lot of previous doctors had suggested (probably to get more money out of me), but I knew that I would ideally like it to be more toned. Picking the right plastic surgeon for me was extremely important and I thought it was going to take a lot of time, but after my first consultation with Dr. Rosen and his team, I knew that I had found the right place. As soon as I walked into their office in Montclair, I was waiting for my appointment for less than 5 minutes and the doctors were already ready to see me! I sat with Dr. Rosen in his office to casually discuss what I was looking to get. I did not feel rushed at all and did not feel as though he was attempting to upsell me in any way, which made me feel extremely comfortable and made me immediately trust and believe everything he was saying! I told him that I was interested in this new non-invasive fat-freezing procedure called Coolsculpting. He thoroughly explained how the whole process would work and then had me checked out by his daughter, Steph, who was extremely professional and a sweetheart to work with! She also called in their aesthetician, Jessica, and they both examined my stomach to make sure that Coolsculpting was the right procedure for my body, and it was! I am extremely excited to go for my appointment. I highly recommend the Plastic Surgery Group for anyway looking for an upscale plastic surgery practice, with many non-surgical options. They are an example of what consultations should always be like! Thank you Dr. Rosen, Steph, Jess & the rest of the PSG team! Stay tuned for my review of the results!!! 🙂 Oh! and if you have some time on your hands while you're there, ask about their Medi-Spa and 3-minute Skin Type Solutions test, you won't regret it!

From the moment you enter the office at the plastic surgery group you feel at ease and warmly welcomed. The office is beautifully appointed with good current magazines. The staff is warm and personable. They really work as a team and that is reflected in their contentment and commitment to their jobs. They are true professionals that deeply care about their clients.

Physician Assistant, Stephanie Rosen is an absolute delight to work with! To say I was little nervous to start 'preventative work' is an understatement. Stephanie quickly settled any nerves by answering all questions professionally and thoroughly. I've followed Stephanie over the past 2 years from her prior employer in Manhattan to The Plastic Surgery Group in Montclair. Words can't describe how much I TRUST Stephanie and her team... they're simply the BEST!

Complications from breast augmentation surgery are rare, but we do see them at the Plastic Surgery Group of New Jersey. The overwhelming majority of our breast augmentation patients enjoy their implants for many years, but occasionally we see patients from other practices that have developed a complication and require additional or revision surgery to fix [...]
