I've been going to Nicole Murnin for my Botox and lip filler, and I honestly couldn't be happier. She has such an incredible eye for detail and always knows exactly how to enhance my features while keeping everything looking natural, and never frozen or overfilled. If you're looking for someone you can completely trust with your face, Nicole is the one.

Form and Function is truly the most amazing medical spa I have ever been to! They have addressed so many of my concerns, from my skin and weight to my stress levels and hormones. Every visit feels personalized, and they genuinely care about helping you look and feel your best.

★★★★★
I've been having some of the best experiences at Form and Function Aesthetics and Wellness. I have a long history of low back pain from ultra running, tactical rucking, ultra running, and competition jiujitsu. I did some research in the Emsculpt NEO, found that the service was provided at Form and Function, and decided to try it out. The pain in my lumbar region has reduced drastically! Thus, I'm super happy.
