*908D. The ALJ’s Findings
The ALJ made the following findings:
1. [Plaintiff] meets the insured status requirements of the Social Security Act through September 30, 2014.
2. [Plaintiff] has not engaged in substantial gainful activity since October 1, 2009, the alleged onset date (20 C.F.R. ■404.1571 et seq.)
3. [Plaintiff] has the following severe impairments: depression, obesity and degenerative disc diséase (“DDD”) (20 C.F.R. 404.1520(c)).
4. [Plaintiff] does not have an impairment or combination of impairments that meets or medically equals the severity of one the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1 (20 C.F.R. 404.152(d), 404.1525 and 404.1526)..
,5. After careful consideration of the entire record, the undersigned finds that [plaintiff] has the RFC to perform medium work as defined in 20 C.F.R. 404.1567(c) except; she can only perform simple unskilled work that does not involve production pace work and only occasional changes in the work-setting. [Plaintiff] must be essentially isolated with having only occasional contact with the public, co-workers and supervisors.
6. [Plaintiff] is unable to'perform any past relevant work (20 C.F.R. 404.1565).
7. [Plaintiff] was born on February 14; 1964 and was 45 years old, which is defined as a younger individual age 18-49, on the alleged disability onset date (20 C.F.R. 404.1563).
8. [Plaintiff] has at least a high school education and is able to communicate in English (20 C.F.R. 404.1564).
9. Transferability of job skill's is not material to the determination of disability because using the Medical-Vocational Rules as a framework supports a finding that the claimant is “not disabled,” whether or not [plaintiff] has transferable job skills (See SSR 82-41 and 20 C.F.R. Part 404, Subpart P, Appendix 2).
10. Considering [plaintiffs] age, education, work experience, áhd residual functional capacity, there' are jobs that exist in significant numbers in the national economy that [plaintiff] can perform (20 C.F.R. 404.1569' and 404.1569(a)).
11. [Plaintiff] has not been under a disability, as defined in the Social Security Act, from October 1, 2009, through the date of this decision (20 C.F.R. 404.1520(g)).
(D.I. 9-2 at 25-31)
III.STANDARD OF REVIEW
Findings of fact made by the ALJ, as adopted by the Appeals Council, are conclusive if they are supported by substantial evidence. Accordingly, judicial review of the ALJ’s decision is limited to determining whether “substantial evidence” supports the decision. See Monsour Med. Ctr. v. Heckler, 806 F.2d 1185, 1190 (3d Cir.1986). In making this determination, a reviewing court may not undertake a de novo review of the ALJ’s decision and may not re-weigh the evidence of record. See id. In other words, even if the' reviewing court would have decided the case differently, the ALJ’s decision must be affirmed if it is supported by substantial evidence. See id. at 1190— 91.
The term “substantial evidence” is defined as less than a preponderance of the evidence, but more than a mere scintilla of evidence. As the United States Supreme Court has noted, -substantial evidence “does not mean a large or significant amount of evidence, but rather such relevant evidence as a reasonable mind might accept as. adequate1 to support a conclusion.” Pierce v. Underwood, 487 U.S. 552, *909565, 108 S.Ct. 2541, 101 L.Ed.2d 490 (1988). The Supreme Court also has embraced this standard as the appropriate standard for determining the availability of summary judgment pursuant to Federal Rule of Civil Procedure 56, The inquiry performed is the threshold inquiry of determining whether there is the need for a trial — whether, in other words, there are any genuine factual issues that properly can be resolved only by a .finder of fact because they may reasonably be resolved in favor of either party.
This standard mirrors the standard for a directed verdict under Federal Rule of Civil Procedure 50(a), “which is that the trial judge must direct a verdict if, under the governing law, there can be but one reasonable conclusion as to the verdict. If reasonable minds could differ as to the import of the evidence, however, a verdict should not be directed.” See Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250-51, 106 S.Ct. 2505, 91 L.Ed.2d 202, (1986) (internal citations omitted). Thus, in the context of judicial review under § 405(g), “[a] single piece of evidence will not satisfy the substantiality test if [the ALJ] ignores, or fails to resolve, a conflict created by countervailing evidence. Nor is evidence substantial if it is overwhelmed by other evidence — particularly certain types of evidence (e.g., that offered by treating physicians) — or if it really constitutes not evidence but mere conclusion.” See Brewster v. Heckler, 786 F.2d 581, 584 (3d Cir.1986) (quoting Kent v. Schweiker, 710 F.2d 110, 114 (3d Cir.1983)). Where, for example, the countervailing evidence consists primarily of the plaintiffs subjective complaints of disabling pain, the ALJ “must consider the subjective pain and specify his reasons for rejecting these claims and support his conclusion with medical evidence in the record.” Matullo v. Bowen, 926 F.2d 240, 245 (3d Cir.1990).
“Despite the deference due to administrative decisions in disability benefit cases, ‘appellate courts retain a responsibility to scrutinize the entire record and to reverse or remand if the [Commissioner’s] decision is not supported by substantial evidence.’” Morales v. Apfel, 225 F.3d 310, 317 (3d Cir.2000) (quoting Smith v. Califano, 637 F.2d 968, 970 (3d Cir.1981)). “A district court, after reviewing the decision of- the [Commissioner] may, under 42 U.S.C. § 405(g) affirm, modify, or reverse the [Commissioner’s] decision with or without a remand to the [Commissioner] for rehearing.” Podedwomy v. Hams, 745 F.2d 210, 221 (3d Cir.1984).
IV. DISCUSSION
A. Regulatory Framework
' Social Security Administration regulations incorporate a sequential evaluation process for determining whether a claimant is under a disability. 20 C.F.R. § 404.1520. The ALJ first considers whether the claimant is currently, engaged in substantial gainful activity. If he is not, then the ALJ considers in the second step whether the claimant has a “severe impairment” that significantly limits his physical or mental ability to perform basic work activities. If the claimant suffers a severe impairment, the third inquiry is whether, based on the medical evidence, the impairment meets the criteria of an impairment listed in the “listing of impairments,” 20 C.F.R, pt. 404, subpt. P, app. 1 (1999), which result in a presumption of disability, or whether the claimant retains the capacity to work. If the impairment does not meet the criteria for a listed impairment, then the ALJ assesses in the fourth step whether, despite the severe impairment, the claimant has the residual functional capacity to perform his or her past work. If the claimant cannot perform his or her past work, then step five is to determine *910whether there is other work in the national economy that the claimant can perform. Sykes v. Apfel, 228 F.3d 259, 262-63 (3d Cir.2000) (citing 20 C.F.R. § 404.1520). If the ALJ finds that a claimant is disabled or not disabled at any point in the sequence, review does ' not proceed to the next step. 20.C.F.R. § 404.1520(a). It is within the ALJ’s sole discretion to determine whether an individual is disabled or “unable to work” under the statutory definition. 20 C.F.R. § 404.1527(e)(1). ■
The ALJ is required to evaluate all of the medical findings and other evidence that supports a physician’s statement that an individual is disabled. The opinion of a treating or primary physician is generally given controlling weight when evaluating the nature and severity of an individual’s impairments. However, no special significance is given to the source of an opinion on other issues which are reserved to the ALJ, such as the ultimate determination of disablement, 20 C.F.R. §§ 404.1527(e)(2) & 404.1527(e)(3). The ALJ has the discretion to weigh any conflicting evidence in the case record and make a determination. 20 C.F.R. §§ 404.1527(c)(2).
B. Arguments on Appeal
On appeal, plaintiff contends that the ALJ failed to: (1) properly weigh medical evidence of treating physicians; and (2) properly evaluate plaintiffs credibility. (D.I.12) Defendant counters that.the ALJ’s RFC assessment included all of plaintiffs functional limitations that were supported by the record. (D.I.14) Further, the ALJ reasonably concluded that plaintiffs subjective complaints of disabling mental and physical limitations were only partially credible considering plaintiffs daily activities, the medical evidence, treatment course and effectiveness.
1. Weight of medical evidence
Plaintiff contends the ALJ improperly disregarded the opinions of her treating psychiatrist (Dr. Desai) and physician (Dr. Tucker). Generally, the weight afforded to any medical opinion is dependent on a variety of factors, including the degree to which the opinion is supported by relevant evidence and consistent with the record as a whole. 20 C.F.R. § 404.1527(c)(3)-(4). -To that end,' the more consistent an opinion is with the record as a whole, the more weight is given to that opinion. 20 C.F.R. § 404.1527(c)(4).
A treating physician’s opinion does not warrant controlling weight under the regulations unless it is well supported by clinical and laboratory diagnostic findings and consistent with other substantial evidence. Fargnoli v. Massanari, 247 F.3d. 34, 42 (3d Cir.2001); 20 C.F.R. § 404.1527(c)(2). The more a treating source presents medical signs and laboratory findings to support his/her medical opinion, the more weight it is given. Id. Likewise, the more consistent a treating physician’s opinion is with the record as a whole, the more weight it should be afforded. Id. An ALJ may only outrightly reject a treating physician’s assessment based on contradictory medical evidence or a lack of clinical data supporting it, not due to his or her own credibility judgments, speculation or lay opinion. Morales v. Apfel, 225. F.3d at 318; Lyons-Timmons v. Barnhart, 147 Fed.Appx. 313, 316 (3d Cir.2Q05).
Even when the treating source opinion is .not afforded controlling weight, it does not follow that it deserves zero weight. Instead, the ALJ must apply sew eral factors in determining how much weight to assign it. Gonzalez v. Astrue, 537 F.Supp.2d 644, 662 (D.Del.2008). These factors include the nature and extent of the treatment relationship, the *911length of the treatment relationship, the frequency of examination, supportability of the opinion afforded by the medical evidence, consistency of the opinion with the record as a whole, , and the specialization of the treating source. Id, If an ALJ does not conduct this analysis, a reviewing court cannot determine whether the ALJ actually considered all the relevant evidence, and the ALJ’s decision cannot stand. Id.
Considering this authority against the instant record, the court finds that the ALJ did not err in considering the opinions from Dr. Desai or Dr. Tucker. The record demonstrates that once plaintiff became compliant with treatment and medication, her symptoms improved significantly. The ALJ correctly found that neither Dr. Desai nor Dr. Tucker’s opinions were consistent with plaintiff’s level of functioning after she became compliant. The ALJ reasonably afforded little weight to Dr. Desai’s opinions in light of his own findings 'that plaintiffs mood improved once medication was adjusted. Further, the ALJ considered Dr. Desai’s opinion and added within the RFC that plaintiff could only perform simple unskilled work. Similarly, the ALJ reasonably concluded that Dr. Tucker’s opinion that plaintiffs bipolar disorder precluded her ability to perform any work was. not supported by the record evidence.
To the extent that plaintiff asserts that the ALJ did not consider all relevant evidence, the Third Circuit has stated that there is no requirement for the ALJ to discuss or refer to every piece of evidence of the record, as long as the reviewing court can discern the basis of the decision. Fargnoli v. Massanari, 247 F.3d at 42. The ALJ at bar stated that she considered all the evidence of record. See Black v. Apfel, 143 F.3d 383, 386 (8th Cir.1998) (the mere failure to cite to specific evidence does not establish that the ALJ failed to consider it); Carlson v. Shalala, 999 F.2d 180, 181 (7th Cir.1993) (the ALJ need not evaluate in writing every piece of evidence submitted). Having considered the ALJ’s decision, it is evident that she considered all the record evidence and provided sufficient reasons for the court to discern her decision.
2. Plaintiffs credibility
When making determinations as to a claimant’s credibility, an ALJ must “determine the extent to which a claimant is accurately stating the degree of pain or the extent to which he or she is disabled by it.” Hartranft v. Apfel, 181 F.3d 358, 362 (3d Cir.1999). In assessing plaintiffs credibility, the ALJ found that her allegations that she is completely unable to perform any work activities is not supported by the medical evidence of record. Specifically, plaintiff decided independently to stop working after receiving a diagnosis of bipolar disorder, not because any physician told her to do so. Plaintiffs hospitalizations occurred when she was not compliant with ' medication and therapy. Plaintiff testified that the medications have somewhat stabilized her mood. She also acknowledged being able to get along with family members, driving, cooking and caring for her two young grandchildren. Significantly, during appointments with Horizon and Dr. Lifrak, plaintiff reported feeling well, with no manic episodes and acknowledged significant improvement in her mental health. The ALJ’s reasons are supported by the reeprd evidence and the court finds no reason to disturb the findings. See Metz v. Federal Mine Safety and Health Review Com’n, 532 Fed.Appx. 309, 312 (3d Cir.2013), (“Overturning an ALJ’s credibility determination is an ‘extraordinary step,’ as credibility determinations ,are entitled to a great deal of deference.”).
