She graduated with highest honor, summa cum laude, from Purdue University with her master’s degree and has dedicated the last 8 years to specializing in aesthetics.

Throughout her journey, she has seen how powerful it is when people take control of their health from the inside out.

She was Inspired to open up a clinic with the mission to help both men and women feel and function at their best—from the inside out. Her approach is rooted in evidence-based medicine, personalization, and genuine connection.

We require a 24-hour notice for cancellations. When you make an appointment that time is reserved only for you. Staff members have been scheduled specifically for you at that time. If at the last moment you don’t show up for your appointment, no other person will be able to fill that spot, yet we have incurred the fees for staffing that appointment. This creates an unfair financial burden as well as being unfair to the patients who would have wanted to be seen at that time. For this reason, cancellations less than 24 hours or no shows are subject to a $50 cancellation fee.
No, we do not work with Insurance companies, however we will give you a superbill if your insurance will reimburse you for the medication. Most weight loss medications and peptides are not covered by insurance.
We are unable to accept Medicare and Medicaid clients, due to current federal billing rules. We refer any inconvenience this causes.
