I was super nervous to get my Kybella treatments but she took her time to explain, go over any questions or concerns that I had. Her and her staff were amazing!! My procedure was fast and painless. She is very experienced in her work, I've even referred a few of my family to her! I will be going back for future touch ups!

I've been seeing Dr. Zaleski for a while for my acne and would recommend her to anyone I know. She is always attentive, polite, and professional. She takes the time to listen to what you have to say and answer all your questions. I recently got some botox done to help with the wrinkles around my eyes and on my forehead. Dr. Zaleski did the injections and the results were fantastic. There was absolutely no bruising and within 5 minutes of getting it done, the swelling was gone. It looks great!

Dr. Zaleski is one of the most kind and caring doctors I have ever met. I'm 47 and have never had a doctor talk to me on the phone when I had questions and explain what's going on with my condition like she has. Most doctors come in to see you and run out as fast as they can to get to the next patient. I just can't say enough nice things about her she's not only a great Dermatologist she's a very kind and caring woman. And her staff is great too they are courteous and organized.
