Meet Mutahir Farhan

MD, AAHIVS

Patients served: Adults (18+)

I aim to create a warm, safe, and non-judgmental space where you feel genuinely seen, heard, and understood. My clinical approach is rooted in empathy, evidence-based care, and whole-person understanding. Whether we’re navigating ADHD, anxiety, depression, or substance use concerns, I believe healing begins with trust and collaboration. I take the time to listen to your story—not just your symptoms—and work with you to build a plan that fits your life, not the other way around. I value honesty, curiosity, and cultural humility in every patient relationship. My goal is to empower you with the tools, insights, and support you need to take ownership of your mental health journey. I also bring a trauma-informed lens to my practice. Many people I work with have gone through years of feeling dismissed or misdiagnosed. I strive to change that experience and help you find clarity, relief, and long-term strategies that work. Whether through behavioral tools, medication, lifestyle changes, or all of the above, we move at your pace—together.

Clinical Expertise

“I’m a board-certified physician in HIV Medicine and board-eligible in Addiction Medicine, with a strong foundation in primary care, mental health, and telehealth-based models of care. I completed my residency in family medicine and went on to pursue an Addiction Medicine fellowship at the University of California, Irvine, through the HRSA-funded TNT-PC TEAM program, where I focused on integrated care for individuals with substance use disorders and co-occurring medical and psychiatric conditions.

In addition to my current clinical work, I’m furthering my specialization in adolescent addiction through advanced training at Harvard Medical School. My goal is to better serve youth and transitional-age populations facing rising rates of substance use, mental health challenges, and limited access to developmentally appropriate care.

Clinically, I’ve worked across a range of settings—from academic hospitals and community clinics to national telemedicine platforms. I currently provide care through ADHD Online and in telehealth-based obesity medicine and primary care. My patient population spans all ages, but I focus especially on adults and adolescents navigating ADHD, anxiety, depression, substance use disorders, and HIV.

Beyond clinical care, I’ve led public health education efforts reaching over 1.3 million people through social media, collaborated with the World Health Organization on digital health campaigns, and remain deeply committed to closing gaps in access through innovative, patient-centered care delivery.”

Education & Degrees

UC Riverside – Medical Doctorate (M.D.)

What made you want to join the ADHD Online team?

“I work with ADHD Online because it aligns perfectly with my mission: to increase access to high-quality, evidence-based mental health care—especially for individuals who’ve historically been underserved or overlooked. With my background in addiction medicine and primary care, I’ve seen firsthand how often conditions like ADHD are underdiagnosed or mismanaged, particularly in adults. Many of my patients who struggled with addiction also had untreated ADHD, anxiety, or other comorbid mental health issues that went unrecognized for years. Early and accurate diagnosis can change lives.

I specialize in treating ADHD, anxiety, depression, and substance use disorders because they frequently overlap, and managing them holistically is essential for long-term outcomes. My work with the World Health Organization, experience in medical education, and passion for using technology to close care gaps all guide this approach.

Telehealth is a natural extension of that philosophy. It removes barriers—like geography, stigma, and wait times—that often keep people from getting help. For many patients, especially those balancing demanding schedules, caregiving roles, or social anxiety, telehealth makes consistent mental health care not only possible, but sustainable. It’s a scalable solution to a national need—and one I’m proud to be advancing through platforms like ADHD Online.”

Curious about stimulant or non-stimulant approaches?

These terms refer to certain approaches to treat diagnosed ADHD. Mentavi Health / ADHD Online may provide stimulant approaches (certain medications under medical treatment that are generally considered Class II controlled substances) or non-stimulant approaches (medications generally not considered Class II, and/or therapy and coaching not related to medication).

A diagnosis and initial conversation with our treatment clinicians is key to the best path for you. The diagnosis is a key first step to determine if you have ADHD or other related conditions. Approximately 60% of patients with ADHD have co-occurring conditions such as anxiety or depression, for example. At the same time, patients who believe they have ADHD may not even have it. For those who do, there can be a variety of considerations into what kind of treatment works best to meet the patient where they’re at.

If you are not feeling right, your journey starts with the first step of diagnostic evaluation.

There may be a brief delay in service today between 12:30 PM and 1:30 PM ET. Thank you for your patience — we look forward to assisting you shortly.
