Our Services

Cardiovascular health monitoring

Annual Wellness Checks

An annual wellness exam is a yearly appointment with your primary care doctor focused on preventive care to maintain your health and create a personalized plan for the future. It includes reviewing your health history, medications, and lifestyle, discussing a schedule for screenings and vaccinations, and checking vital signs like blood pressure and weight. Unlike an annual physical, it typically does not involve a hands-on physical examination unless there is a specific issue to address.

Wound care

Advanced Wound Care

Advanced wound care is a specialized, comprehensive, and multidisciplinary approach to managing complex, non-healing wounds that have not responded to conventional treatments. It leverages cutting-edge technologies, advanced dressings, and evidence-based practices to promote faster healing, reduce complications (such as infection or amputation), and improve a patient’s quality of life.

IV Treatments

IV treatments, or intravenous (IV) therapy, involve administering fluids, medications, nutrients, or blood products directly into a patient’s bloodstream via a vein. This method ensures rapid absorption and immediate distribution throughout the body by bypassing the slower digestive system. IV treatments use a small, flexible tube (catheter) inserted into a vein, typically in the arm, connected to an IV bag of sterile fluid. This setup allows substances to enter the circulatory system quickly. 
 
The primary advantage of IV therapy is the speed and efficiency with which substances can reach the body’s tissues.
Geriatric patient

Geriatric Care

  • Comprehensive Geriatric Assessment: A thorough evaluation that covers medical health, mental health, functional ability (daily activities like dressing and eating), social support, and environmental safety.
  • Management of Multiple Chronic Conditions (Multimorbidity): Older adults often have several health issues at once (e.g., diabetes, heart disease, arthritis). Geriatric specialists manage these conditions in a coordinated way to prevent harmful drug interactions and prioritize treatments.
  • Focus on Function and Independence: A core goal is to help patients maintain the highest possible level of independence for as long as possible, often involving physical therapy, occupational therapy, and nutritional counseling.
  • Preventive Care: Emphasis is placed on preventing common issues in older age, such as falls, infections, medication errors, and cognitive decline.
  • Palliative and End-of-Life Care: Geriatric specialists help manage symptoms and provide comfort care for older adults with serious illnesses, ensuring their wishes regarding end-of-life care are respected. 
Geriatric care is essential for several reasons:
  • Unique Health Challenges: Older adults experience health issues differently than younger populations. Diseases may present with subtle or atypical symptoms (e.g., a heart attack might present as confusion or fatigue rather than chest pain), requiring specialized knowledge to diagnose correctly.
  • Complexity of Medication Management (Polypharmacy): Older adults often take multiple medications, increasing the risk of adverse drug reactions and interactions. Geriatric specialists are trained to streamline medication lists and reduce unnecessary prescriptions.
  • Addressing Functional Decline: Geriatric care helps address age-related changes in mobility, balance, strength, and cognitive function, which significantly impact daily life and safety.
  • Improving Quality of Life: By coordinating care and focusing on the patient’s goals and values, geriatric specialists help older adults live more comfortably and meaningfully, rather than just managing diseases in isolation.
  • Support for Caregivers: Geriatric care extends support and education to family members and caregivers, helping them navigate the challenges of caring for an aging loved one and preventing burnout.

Hormone

H.R.T.

Hormone replacement therapy (HRT), specifically testosterone replacement therapy (TRT), offers several benefits for men experiencing symptoms of low testosterone (hypogonadism). The primary advantage is the alleviation of distressing symptoms that can significantly impact well-being, such as chronic fatigue, low energy levels, reduced muscle strength and mass, increased body fat, decreased libido, erectile dysfunction, and brain fog or reduced mental clarity. By restoring testosterone levels to a normal, healthy range, TRT can substantially improve quality of life by enhancing vitality, mood stability, and cognitive function. Furthermore, TRT helps maintain bone density and muscle mass, which reduces the risk of osteoporosis and physical frailty common in older age. Men often report improved sexual health and overall energy, allowing them to lead more active and engaged lives. The decision to begin TRT is a personal one and should be discussed with a healthcare provider to ensure the benefits outweigh potential risks for an individual’s specific health profile.

Cognitive Assessment Therapy

Cognitive assessment is the process of evaluating a person’s mental abilities, including memory, attention, language, reasoning, and problem-solving skills, through standardized tests and procedures. The results help healthcare providers identify cognitive strengths and weaknesses, diagnose conditions like dementia, ADHD, or learning disabilities, and create personalized care plans. While “cognitive assessment therapy” is not a standard term, the assessment results are crucial for informing subsequent interventions, such as cognitive behavioral therapy (CBT), which helps individuals manage thought patterns and behaviors, or cognitive rehabilitation, which provides strategies to maintain independence and manage daily tasks after a brain injury or the onset of conditions like early-stage dementia.

Diabetic Neuropathy Pain Treatment

Treatment for the burning, aching, or electric-shock type pain associated with diabetic neuropathy involves a multidisciplinary approach focused on managing blood sugar and alleviating symptoms, as there is currently no cure for the underlying nerve damage. The most crucial aspect of care is rigorous glycemic control through diet, exercise, and medication, which helps to slow or halt the progression of further nerve damage. For existing pain, physicians typically prescribe specific medications that have proven effective for neuropathic pain, even if not originally intended for it. Common first-line oral options include anticonvulsants such as pregabalin and gabapentin, which work by calming overactive nerve signals, and certain types of antidepressants, specifically serotonin-norepinephrine reuptake inhibitors (SNRIs) like duloxetine and venlafaxine, or older tricyclic antidepressants (TCAs) like amitriptyline. These medications modify pain perception pathways in the brain. For localized relief with fewer systemic side effects, topical treatments like over-the-counter capsaicin cream or prescription-strength lidocaine patches are often recommended. A comprehensive management plan also incorporates non-pharmacological approaches, including physical therapy to improve strength and mobility, transcutaneous electrical nerve stimulation (TENS), acupuncture, and certain dietary supplements. In cases of severe, refractory pain, advanced interventions such as high-frequency spinal cord stimulation may be considered by specialists. Patients often need to try several medications or a combination of therapies to find the most effective pain relief strategy, requiring close collaboration with their healthcare team to manage side effects and optimize outcomes, ultimately improving their quality of life.

Arterial & Venous Vascular Doppler Scans

Arterial and venous vascular Doppler scans are non-invasive diagnostic tests that use high-frequency sound waves (ultrasound) to evaluate blood flow within arteries and veins throughout the body. A handheld transducer is moved over the skin, bouncing sound waves off red blood cells; the resulting echoes are converted into images and graphs on a monitor, allowing healthcare providers to assess circulation.

These scans serve distinct purposes for different parts of the circulatory system:

Arterial Doppler Scans: These tests examine blood flow in the arteries and are primarily used to detect blockages or narrowing caused by plaque buildup (atherosclerosis). They are critical for diagnosing conditions like peripheral artery disease (PAD) in the legs and carotid artery disease in the neck, which are major risk factors for heart attack and stroke, respectively.

Venous Doppler Scans: These scans focus on the veins and are instrumental in detecting blood clots, particularly deep vein thrombosis (DVT), often in the legs. DVT can lead to a potentially life-threatening pulmonary embolism if a clot travels to the lungs. Venous scans also help diagnose chronic venous insufficiency, a condition where damaged valves cause blood to pool in the legs.

EKG

An electrocardiogram (EKG or ECG) is a common, non-invasive diagnostic test that records the electrical signals produced by the heart with each beat
. It is a quick and painless procedure where small electrodes are placed on the chest, arms, and legs to detect and amplify these electrical impulses, which are then represented as waves on a monitor or paper printout. The primary benefit of an EKG is its ability to rapidly assess heart function, helping healthcare providers diagnose a wide range of cardiac conditions. It is an essential tool for detecting irregularities in heart rhythm (arrhythmias), identifying if a patient is currently having or has previously had a heart attack, determining poor blood flow to the heart muscle (ischemia), and evaluating the overall efficiency of the heart’s electrical system. This immediate, comprehensive snapshot of heart activity allows physicians to make timely and accurate medical decisions, often in emergency situations, to prevent further cardiac complications and guide treatment planning.

ABI

An Ankle-Brachial Index (ABI) is a simple, quick, and non-invasive test used to screen for peripheral artery disease (PAD), a condition where narrowed arteries reduce blood flow to the limbs. The procedure involves a healthcare provider using a standard blood pressure cuff and a handheld ultrasound (Doppler) device to measure the systolic blood pressure in both arms and both ankles. The ratio of the ankle pressure to the arm pressure determines the index. A normal ABI score typically ranges from 1.0 to 1.4; a lower number suggests reduced blood flow and potential blockages in the leg arteries, while a higher number may indicate stiff arteries, often due to advanced diabetes. The primary benefit of the ABI test is its ability to provide early detection of PAD, which allows for timely intervention through lifestyle modifications or medication, significantly reducing a patient’s risk for complications like leg pain during walking (claudication), non-healing ulcers, limb loss, heart attack, and stroke.

Echocardiograms

An echocardiogram, often referred to as an “echo,” is a vital, non-invasive diagnostic test that uses sound waves to create moving pictures of the heart. Similar to an ultrasound, a technician applies gel to a transducer which is moved across the chest, sending sound waves that bounce off heart structures to generate detailed images on a monitor. The primary benefit of an echocardiogram is its ability to provide a comprehensive, real-time assessment of the heart’s structure and function. It allows physicians to visualize the size and shape of the heart, evaluate how well the chambers and valves are working, check the force of the heart’s contractions, and look for signs of damage from a prior heart attack or disease. This critical information helps diagnose numerous cardiac conditions, including heart valve problems, heart failure, congenital heart defects, and endocarditis, enabling physicians to accurately determine the best course of treatment.
