Usanovic alleged that EXP directed its agents to place unsolicited calls to consumers’ telephone numbers who are registered on the National Do Not Call Registry (“NDNCR”), “including those consumers who requested for the calls to stop.” Usanovic also submitted the expert report of [Anya Verkhovskaya](https://expertwitnessprofiler.com/expert-witness/Anya-Verkhovskaya/1522893), who contended that there is a reliable method to identify residential telephone numbers that were on the NDNCR for 32 or more days and received two or more connected calls from or on behalf of an EXP agent within a 12-month period between May 10, 2019, through the class certification period. However, EXP filed a motion to exclude Verkhovskaya’s expert testimony on the bases that her proposed methodology did not reliably identify (1) residential numbers on the NDNCR and (2) calls that violate the TCPA. ## **Class Action Expert Witness** [Anya Verkhovskaya](https://expertwitnessprofiler.com/expert-witness/Anya-Verkhovskaya/1522893) has more than two decades of experience serving as an expert witness or court-approved administrator in various class action matters, including hundreds of TCPA cases and consumer protection, employment, antitrust, securities fraud, ERISA, human and civil rights, and other class action claims.

Moreover, courts across the country have concluded that Verkhovskaya’s methodology is reliable and sufficiently capable of identifying putative class members. It is widely used in TCPA class actions, including in multiple cases against real estate brokerages arising from calls by their affiliated agents. Finally, that Verkhovskaya’s methodology potentially resulted in errors in the proposed class list, such that some of the members of the proposed class list did not meet the class definition or are associated with the incorrect phone number, did not warrant exclusion of her testimony. Thus, in keeping with sister courts across dozens of districts, the Court declined to exclude Verkhovskaya’s opinions on the grounds that her methodology is unreliable. ## **Held** The Court denied the motion to exclude the opinions of expert witness Anya Verkhovskaya. ## **Key Takeaway** The focus in a _[Daubert](https://www.law.cornell.edu/wex/daubert_standard)_ challenge is not primarily concerned with a proposed expert’s conclusions but with making a preliminary assessment of whether the methodology underlying the testimony is scientifically valid and of whether that methodology properly can be applied to the facts in issue. ## **Case Details:** --- ## **You Might Also Like** ![Chemical Engineering Expert's Testimony on Catalyst Damage Excluded](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-10T190614.043.jpg) [**Chemical Engineering Expert’s Testimony on Catalyst Damage Excluded**](https://expertwitnessprofiler.com/class-action-experts-testimony-on-residential-telephone-numbers-admitted/chemical-engineering-experts-testimony-on-catalyst-damage-excluded)![Plant Pathology Expert Allowed to Opine on HLVd Infection](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-10T122000.228.jpg) [**Plant Pathology Expert Allowed to Opine on HLVd Infection**](https://expertwitnessprofiler.com/class-action-experts-testimony-on-residential-telephone-numbers-admitted/plant-pathology-expert-allowed-to-opine-on-hlvd-infection)![Chemical Engineering Expert Allowed to Opine on Railcar Switching](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-08T195023.873.jpg) [**Chemical Engineering Expert Allowed to Opine on Railcar Switching**](https://expertwitnessprofiler.com/class-action-experts-testimony-on-residential-telephone-numbers-admitted/chemical-engineering-expert-allowed-to-opine-on-railcar-switching)![Industrial Hygiene Expert Not Allowed to Opine on Falling Debris](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-08T175126.051.jpg) [**Industrial Hygiene Expert Not Allowed to Opine on Falling Debris**](https://expertwitnessprofiler.com/class-action-experts-testimony-on-residential-telephone-numbers-admitted/industrial-hygiene-expert-not-allowed-to-opine-on-falling-debris)![Architecture Expert Not Allowed to Opine on the Safety of Retail Escalators](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-08T143944.585-1.jpg) [**Architecture Expert Not Allowed to Opine on the Safety of Retail Escalators**](https://expertwitnessprofiler.com/class-action-experts-testimony-on-residential-telephone-numbers-admitted/architecture-expert-not-allowed-to-opine-on-the-safety-of-retail-escalators)
