Chalgren, Meet Rhythmlink! 

Rhythmlink International, LLC has acquired Chalgren Enterprises, and we look forward to working with each of you to provide the products and materials you need. Rhythmlink plans on maintaining the high quality and availability of Chalgren's products and services that Chalgren has offered to you over the years. Much will stay the same, but as with any acquisition, a few things will change. Beginning March 1, orders will be processed through Rhythmlink.

Emails sent to Chalgren will be forwarded to, and calls will be directed to our sales line at 866.633.3754. We can’t wait to speak with you!

Additionally, orders will begin shipping from our headquarters in Columbia, SC. For some of you, this will mean a shorter transit time, for others longer. Our excellent customer service team will work with you to select the shipping method that best meets your needs.

Finally, the remittance address for your payments will change. Beginning March 1, payments should be sent to Dept#141, P.O. Box 1000, Memphis, TN 38148.

Some of you may have been with Chalgren from the very beginning, and we know you have come to rely on and enjoy working with a small, personable, and family-owned company. We want to assure you that Rhythmlink is respectful of the relationship that you have forged with Chalgren and we look forward to maintaining and building on that trust. 

Though Rhythmlink is a younger company, we still bring almost two decades of experience in the EEG and IONM markets. Our founders and leadership team have experience in your industry as well, many having worked as neurodiagnostic technicians prior to joining Rhythmlink, bringing with them a unique understanding of your day-to-day needs. We are a small company, with real people, but the growth and expertise we have amassed can help you grow your service the same way we have. 

We’re excited to partner with you. Thank you for being here and trusting Rhythmlink to continue to serve you. If you want to learn more about us, please visit our website at or reach out to us at

Sincerely, Your Rhythmlink Team
