About this clinic

Dr. Mark Neumann, a functional-medicine practice in Lambertville, specializes in hormone optimization through bioidentical hormone-replacement therapy and testosterone therapy, alongside peptide protocols. Treatment plans are individualized following an initial functional-medicine assessment, and the clinic emphasizes natural hormone restoration rather than synthetic pharmaceutical approaches. Peptide therapy is integrated to support metabolic function, tissue repair, and age-related decline. The practice also offers laser therapy for pain management and weight-loss support as adjuncts to its hormone-centered protocols. Patients receive ongoing monitoring as treatments are adjusted to meet individual health goals.

Dr Neumann has always been very thorough and patient with any issues or questions I’ve had. He is kind, personable and easy to talk to. I feel safe to express any and all concerns as I am heard and not rushed out the door before everything is addressed. I would absolutely recommend him. The whole office staff has been very pleasant and kind helping me along with any information I need assistance with.

Dr Klump has been amazing. I am so blessed to have found her. She takes the time to listen and makes me feel supported and understood. I am a work in progress, still figuring things out and I am thankful to have her by my side for each step. Josh and all of the office staff are 💯 awesome!
