I had my Endolift treatment with Dr Hass and couldn’t be happier with my experience. From the initial consultation through to the treatment itself, I felt reassured and well looked after. Dr Hass was professional, knowledgeable and took the time to explain everything clearly, which made me feel at ease throughout. I wanted a subtle, natural-looking result rather than anything drastic, and I felt confident that Dr Hass understood exactly what I was hoping to achieve. The whole experience was positive, and I’m really pleased with the care and attention I received. I would highly recommend Dr Hass to anyone considering Endolift and looking for a professional, reassuring experience.

I recently went to Dr. Hass at Dr. Hass Clinic for an Endolift treatment, and I honestly couldn't be happier with the results! I had quite a bit of sagging skin, especially around my neck and lower face. The moment the procedure was done, I could immediately feel the tightening effect. The results were amazing right away the sagging on my neck completely disappeared, and my facial contours were lifted instantly. Dr. Hass is wonderful, so kind, and extremely professional. He explained everything in detail and took his time to focus precisely on the sagging areas where I needed it the most. I am so satisfied with my experience, I will definitely come back in the future, and I highly recommend him to anyone struggling with similar issues. He is truly one of the best, and I am so glad I found him and chose him!

I had my nose filler done by Dr. Hass, and I couldn’t be happier with the results! His knowledge, expertise and attention to detail were evident straight after the treatment. He understood exactly what I wanted to achieve and delivered the results I was hoping for. He also took the time to guide me through the process and advise me on the best approach to suit my nose and desired outcome. I’m extremely happy and satisfied with my results and would highly recommend Dr. Hass to anyone considering aesthetic treatments.

A very good experience. Dr Hass was professional, thorough and took the time to assess my face properly. The face mapping was very detailed, everything was explained clearly, and the recommendations felt considered rather than rushed. I felt very comfortable throughout.

I am a lady in my early 50s I was very confused to choose a clinic that can remove my double chin which was really annoying me and making me lose my confidence. I finally found Dr. Hass clinic. I am a person who doesn’t like surgeries or injections.. I was very worried but Dr Hass was a very experienced professional doctor who made me feel comfortable and relaxed. I personally didn’t feel any pain and when I saw the result I was amazed with the beautiful change … No more double chin 🥹🥹 It’s very important for all women to invest in their health and beauty.. I strongly recommend Dr Hass clinic and I would love to make another visit for different treatments 😊 Dr Hass you really changed my life by increasing my self confidence thank you so so much for everything 🥹🙏🏼🌹

I’ve been coming to Dr Hass for a long time now and I honestly wouldn’t trust anyone else with my filler. He always makes me feel completely at ease and really takes the time to listen to what I want, while also giving genuinely helpful and honest advice. He’s brilliant at what he does, couldn’t recommend him enough!

I visited Dr Hass for dermal fillers and it was my best experience to date. Dr Hass took time during the consultation to really ask questions to understand my needs and make the best recommendations for me to achieve my desired results. He was honest and personable and even advised me against treatments I thought I needed due to seeing others have these procedures online. He really cared about my results and being satisfied over anything else. I was nervous but he put me at ease and the results are amazing. Cannot recommend the clinic enough and I will be back!

Endolift A huge thank you to Dr. Haas! I had a big issue with sagging skin, especially on my neck, so I decided to get an Endolift for my face with an extended neck treatment. I saw the results immediately after the procedure—my skin was tightened, my facial contours were much more defined, and everything looked so beautiful and natural. I am extremely satisfied, the clinic is clean and gorgeous, and everyone there is so kind. Dr. Haas is truly one of the best doctors, and I highly recommend him to everyone!

Lips I would thoroughly recommend Dr Hass and his clinic. He is incredibly thorough, professional and, most importantly, honest in his approach. Having visited a number of different clinics over the years, what really sets Dr Hass apart is his focus on achieving a softer, fresher and more natural look rather than making you look “done”. He has completely transformed years of previous lip filler for me, and my lips already look amazing — beautifully natural and so much better balanced. I’ve had so many people notice the difference and comment on how good they look. I couldn’t be happier with the results and wouldn’t hesitate to recommend him.

I spent years looking for an effective treatment for my jawline and came across Dr Hass's clinic on instagram. I am extremely happy with the results of endolift and a mini liposuction. The service was exceptional from beginning to the after care. Dr Hass always responds to queries and gives appropriate advice. I would highly recommend his services.
