Not only is Jerry knowledgeable and passionate about what he does, he possesses a plethora of knowledge in pharmaceuticals, skincare, health, etc. He has been a pleasure to work for and has become more of an asset to myself from the knowledge he has provided me with. Highly recommend him for custom skincare products (he made me a glycolic avid treatment that is 35% - unavailable anywhere else, that has done wonders on my skin) as well as any medical needs you have. Even if you just have a question he will be happy to answer it.
