clients have to say...

I would never let anyone else touch my lips! Marissa is the best at what she does and such kind, beautiful soul. Worth every penny!

Stacy Santola

Marissa is the only injector I trust! I’m one of her patients from Florida, and I literally just booked a flight to receive a treatment from her. Provides such thorough education, is honest but not critical, and is not pushy at all. Super natural botox technique that provides a beautiful lift. I’ve lost my sparkle without her and can’t wait to get a refresher when I’m in NY!!

Marissa is the only person that’s ever done work on my face and she’s now the only person I trust. She’s so genuine and knowledgeable, and because of her, I am obsessed with my lips. Highly recommend if you’re looking for undetectable work. 10/10 experience always!!!!!!!!

Marissa is quite literally my favorite person ever!! I used to see her all the time when she lived in South Florida, and now I will fly out to NYC just to see her because absolutely no one else is allowed to touch my face (especially my lips)! She truly is so knowledgeable and a master of her craft. She gave me so much confidence in myself, and I will be forever grateful! Also, she’s just very nice and kind and I just cannot say enough great things about her!

Oh and btw one of my favorite things about her is that she truly has your best interest at heart. She has told me no more than once because she didn’t believe it would suit me/I needed it, and I appreciate that so much! She is the best and very missed here in FL but thankfully just a short flight away

Barbara Martinez

Not only is this location absolutely incredible, Marissa was absolutely incredible!! She is so kind, and so knowledgeable about her work. What she does is truly art!! Love an injector who says “no you don’t need that yet” and allows for the art to speak for itself. Truly the best in the city - run do not walk!!!!!

I had a wonderful experience at Velour Medical with Marissa. She was incredibly professional, gentle, and attentive throughout the entire process. She took the time to understand exactly what I was looking for and made me feel completely at ease. The results are subtle, natural, and exactly what I had hoped for. I’m very happy with the entire experience and will definitely be returning!

Ozge Ozkaya

Marissa is hands down the best there is. I wouldn’t let anyone else touch my lips, she’s truly an artist! I use to see her back in South Florida and will continue to happily take trips to New York just for her. Not only is she so talented she’s also so kind and makes you feel so comfortable. The office itself is also clean and beautiful and the rest of the staff was so nice and welcoming. Would recommend Marissa if you’re looking for that perfect pout that will leave people shocked to find out you’ve gotten filler. If you want flawless lips then you MUST visit Marissa! Looking forward to booking my next appointment this year with her!

Grace Balcazar

SO happy with my experience. Marissa made me feel so comfortable providing me with options, talking through what will be done and what results I can expect. Highly recommend!

Ali Duvaras

Marissa is elite. I went to her at Velour Med Spa about a month ago for DAO & Nefertiti Botox and I’m obsessed with the results — my face looks slimmer, more defined, and still completely natural.

I came in with ideas and she helped me refine everything in a really thoughtful way. She listens, explains, and has an amazing eye for subtle balance. No overdoing it, just clean, elevated work.

She’s officially my go-to nyc pa and the only person I trust with my face. Already planning to come back in the spring for Skinvive. If you want that “you look really good but I can’t tell why” look — book her.

Also… she’s just cool. Love her!!!

Alexa Guerriero

When it comes to my face, I only trust Marissa. She truly listens to what bothers you and knows exactly how to make subtle enhancements that take you from an average 7 to a solid 10 almost instantly. I always feel so comfortable in her hands, and the results are consistently amazing. She basically gave me an upper bleph with just Botox — and I’m obsessed. She’s the best of the best!

Kori Powell

Marissa helped me achieve exactly what I was looking for with my lips! The results have that subtlety I was looking for, while balancing out my face so well. This will make me feel SO confident for my upcoming wedding!

Lauren Pavlat

I got chin filler with Marissa a week ago & just WOW. I had been dying to get an appointment with her. & it was so worth the wait. Her work is like no other. So natural and beautiful. I’m in love with my chin. The biggest confidence boost. I love Marissa she is amazing. Her work is perfection & she is so sweet, kind & honest about what you do and don’t need.

Gianna Munguia

Marissa is a master of her craft! Her attention to detail and expertise is well worth traveling from FL to NY. Every experience I’ve had with her has been nothing short of perfect and I fully encourage EVERYONE to go see her!!

Amy James

The best! See Marissa!

Julia

I had a wonderful experience at Velour Medical! The office space is stunning and everyone was very welcoming. This was my first time receiving services and Marissa really took the time to explain everything and made me feel so comfortable with the whole process. I have the highest praise for Marissa and her work - I could not recommend her and the Velour team enough!

Molly Mahony

Marissa is absolutely amazing! I booked with Marissa for lip filler & I am beyond happy with my result! This is my 2nd time getting lip filler (1st time was not through Velour or with Marissa) & I can truly see such a difference in the quality of Marissa's work. She takes her time explaining what to expect during and after the procedure & ensures your comfort throughout! Marissa is the best & I will continue to book with her and recommend her to absolutely everyone!

Andrea Flores

Marissa is the queen of lip filler. She has magical injecting hands and the quality of her work is unmatched! No one makes me feel more beautiful.

Miriam Rosen

I am SO happy I got to see Marissa at Velour! She is so amazing at what she does and she is the kindest person! I’m really happy I chose to go with her and I will fly out from California to see her! She’s that good!! Also the office is really beautiful!

I truly cannot speak more highly of Marissa and her team!

After recently relocating from DC, I struggled to find an injector in the NJ/NY area whose work I genuinely loved. I had been loyal to the same injector for years, so the transition was tough. I tried two other providers (one in NJ and one in NY) but was completely unhappy with the results.

Then a friend recommended Marissa and TG they did! She is absolutely heaven-sent and clearly an expert in her craft. Marissa is incredibly patient, takes the time to ask thoughtful questions, and is honest about procedures, expected results, and what is realistic. From start to finish, she made me feel comfortable and informed.

I had Botox done on the classic facial areas and I could not be happier with the outcome. Her technique created natural symmetry and subtly lifted and opened my face without it looking overdone. I genuinely loved (and still love!) my results. I can confidently say I have found my forever injector.

Also, the office itself is absolutely gorgeous! Spotless, calming, and beautifully designed. And Bailey, the experience coordinator, is just as lovely, super responsive, kind, and welcoming.

So grateful to have found this team!

Marissa is the sweetest ever. I asked her for an “upper bleph” brow lift using botox and she DELIVERED. I now look so much more awake and happy. I can’t wait to go back and see her again:)

Lindsey Gordon

Marissa is my favorite injector I’ve ever been to, will not let anyone else touch my face ever again! Not only is she incredibly talented at what she does, but she also is insanely kind and will never pressure you to do anything extra or go overboard with filler. She genuinely wants to see her clients happy and that is rare to find these days. Love love love - would 10/10 recommend!!

Jen

I visited Velour to see Marissa last week, she was truly an angel. It was my first time receiving services and she made me feel completely seen, safe and comfortable. Her warmth and sincerity made the entire experience so special. She gave me the most perfect lips and made me feel genuinely confident. I’d trust her with anything, her results speak volumes as does her character and care.

Dagny Horton

When I come to see Marissa, I never feel like I got work done I feel like I just look better!!!! She is amazing!!!!!

Melanie Rista

Marissa is the absolute best injector I have ever encountered, the only person that touches my lips and that I would travel Miami - NYC for. Her skills and attention to detail are immaculate, and above her professionalism is her incredible energy and kindness. She genuinely is gifted at what she does

Marian Karam

I traveled from Florida to see Marissa and she was fantastic! I appreciated how she was honest about what she recommended vs what I didn’t really need, despite my long list of treatments I was prepared to do. We spent plenty of time consulting prior to treatments which made me feel very confident in our treatment plan. Can’t wait to see her again!
