About This Clinician

This clinician is enumerated under Endocrinology, Diabetes & Metabolism. Endocrinologists treat hormonal and metabolic conditions including type 2 diabetes, and frequently prescribe GLP-1 medications such as semaglutide or tirzepatide as part of diabetes or metabolic-syndrome management — though not every endocrinology practice treats obesity as a primary focus, and some see only referred, complex cases.

Locally, this is 1 of 2 Endocrinology, Diabetes & Metabolism practices in Waukesha carrying this exact taxonomy in our directory.

What to expect at an Endocrinology visit

Endocrinology visits focus on hormonal and metabolic conditions. For a GLP-1-related consult, patients commonly encounter:

  • •A review of diabetes, thyroid, or metabolic history and current medications.
  • •Lab work such as A1c and a metabolic panel to guide diagnosis and dosing.
  • •A discussion of whether a GLP-1 medication fits the treatment goal (diabetes control, weight, or both).
  • •Follow-up scheduling to titrate dose and monitor response over time.

This is general guidance for endocrinology practices, not a description of William Crelin's specific protocol, services, or pricing. Confirm what a visit involves directly with the practice — 262-928-9190.
